Thought Experiment: USA NUKED JAPAN

2012-10-20T20:46:00.000-07:00

It is soo hard for our ignorant fellows to comprehend.

[Side note on ignorance: ignorance is lack of knowledge or not knowing. knowledge is opinion that which is your own or that with which you concur. that which cannot be opinion cannot be knowledge. Information i.e. USA nuked Japan in 1945 can be opinion but requires telling, so it can be information, something of which some can be informed of] taken from Marc Rose.

So i am making this post, so that it will help them dudes understand, and help make their point clearer to explain how am i lying. It is awkward singing into a debating group where tons of fellows accuse you of telling lies and suck at explaining their case. i am making this post out of my time, so not spamming, copy pasting stuff and trolling is appreciated. Just as a reminder, a few folks may find the topic of this post "THOUGHT EXPERIMENT: USA NUKED JAPAN" misleading, however it goes beyond as you will notice later and i have left the conclusion for the debating folks.

I have tried to assess the USA act of deciding to "nuke Japan to save its own population" over a thought experiment.

Case:

Trolley coming with high speed

Consider you are working in a mine and there is a trolley coming from track A, there are 10 workers working on track A further on.

You are standing on the platform, where there is a control box. If you pull the lever the train will divert to track B. between the 10 workers and the train, at the movement there is a junction from which stems the track B, where 5 peoples are working.

The control box is within your reach, so you can make a decision. what would that be?

Following are different configuration of the events that can happen due to the decision made.

i) do nothing: 10 people will die.

ii) pull the lever: 5 people will die.

For i) people can argue that "no doing" is not an action, so cannot be held responsible for it. As no action has been done. While one can also say that the importance is to the decision. The decision i.e. letting a difference of 5 people die.

For ii) people can argue that by pulling the lever they have saved 5 lives, which otherwise be destroyed.

The argument in ii) give rise to the philosophy of “consequential moral principle” which dictates that the nature of action is defined by the consequence of the action i.e. if the consequence is good; the action is moral or good. If the consequence is bad; the action is bad or immoral.

Which further give rise to the knowledge of consequence being good or bad? For example in the given case

for i) what if those 10 people who get killed because no action has been done were a great invertors, remarkable scientist or honest statesmen ?
for ii) what if those 10 people who are saved were serial killer, drug trafficker or terrorists?

Conclusion:

I am leaving the conclusion bit for the fellow readers as I promised earlier. The decision is yours, what was the right thing for Americans to do on 6^th and 9^th August 1945?

Was the decision to nuke Japan so that America becomes a threat and destruction of many sovereign nations moral/right?

Would the decision to let Japan destroy America be a moral/right decision?

DT_Tensiometer Test

2012-04-25T17:41:00.000-07:00

Introduction

Tensiometer test is categorized in the Destructive testing, in industry it is used to estimate changes in the different properties of material before it breaks for quality purpose which is achieved by applying stress on specimen with the help of tensiomenter.

Objective

Using the tensiomenter estimate the following properties of the given material on graph:

Elasticity
Plasticity
yield stress
fracture point

Apparatus

Tensiometer
Table
Graph paper
Test materials (i.e. Brass and Carbon steel).

Safety Procedures

Tensiometer is an isolated instrument so we do not have to take much safety precautions however using gloves and eye protection may be essential as the material that we may use drop some particle around. Further the specimen will fly off when it breaks, so the people around must be paying attention.

Test Procedure

Setup the tensiomenter on the table; place a graph paper at the drum of the tensiometer, before fastening the specimen in position we need to reset the gauge to zero (this will be on no load condition), after placing the specimen in position as we put the material in stress condition by turning the cam, as the more stress is applied it began to elongate gradually and finally fails.

While the tensile force is applied we keep marking the reference points which will help determining us the different properties of the material on graph.

Before the material reaches its fracture point and fails it goes through two stages

i) Elastic range

ii) Plastic range

Elastic range is the position wherein the material may show some abnormal behaviour but it can retrieve to its original stage.

Plastic range is the position in which material show the abnormal behaviour but its too late for it to be able to retrieve to its original position.

We repeated the same procedure for two different specimen materials, i,e, brass and carbon steel.

Observation

As the material is elongated (due to the stress applied) the area is reduced. The reduction in area leads the material to its breakdown, apart from few of material was worn down and could be seen under the tensiomenter.

The elongation and reduction in area is noted in both the material. These properties are due to the yield stress that any material has. Brass having lower yield stress breaks with lower stress applied but have more elongation elastic or plastic range (material tend to be less stiff). Carbon steel having higher yield stress has less elongation (both elastic and plastic) but breaks with higher stress applied (material tend to be more stiff).

Result

Brass showed more elongation and Carbon steel showed lesser elongation before it broke. The following schematics are obtained from the graph:

Brass has longer elastic and plastic ranges and lower yield stress and ultimate tensile strength comparable to the carbon steel i.e. carbon steel has short elongation ranges and higher yield stress and ultimate tensile strength.

Conclusion

The higher the yield stress of material, the lesser will be area reduction and hence more force required to deform the material before it reaches its fracture point.

PSSR (Personal Safety & Social Responsibility) for online group (ivsk2.0 closed group)

2012-04-25T11:51:00.001-07:00

1.0 Abstract

There are different criteria for being emotionally compromised for a non religious and a religious. Religious tend to get emotionally compromised by attack on his religion/beliefs/faith and non religious tend to get emotionally compromised by personal attacks.

2.0 Introduction

PSSR for ivsk2.0 is a set of instruction which may help members avoid get into trouble while debate/discussion as it is supposed to be an educational/academic group where members are free to discuss debate and present their view on different topics, matters and aspect of life (majorly those which are mentioned in the group agenda 1.0). All members are required to undertake PSSR for healthy and knowledgeable debate/discussion/sharing views etc. and UNCIVILIZED members are not welcomed. The Codes of Practice (see section 3.0) are the collective work by Asad Ali and Sheba Tillman, however these are also influenced by the group members, Marc Rose, Bill Allen, Bruce Clark and Andy White.

[however these are not reviewed for mistakes and errors, any mistakes, error, flaws found is welcomed to be mentioned and will be updated]

2.1 Significance

There are several members who may not be liked by the existing or new members and were responsible for disrupting communication, insulting, spamming or e-identity fraud (OR internet identity fraud) to achieve personal gain or causing damage to others. However if they are willing to comply with PSSR for ivsk2.0 they well be allowed to enter the group for debate/discussion/sharing views purpose and if found not complying or breaching any of the group regulation or practicing the prior stated things (including disrupting communications) they will be removed. PSSR for ivsk2.0 also requires the existing members to be ethical with the new member irrelevant of their behavior OUTSIDE of the group.

3.0 Codes of practice

Debate or discussion or sharing point of view (opinion) on different matter/topic are to be done with proper reference if not supposed to be or presented as a hypothetical.
Intelligent free speech can/should be practiced (borrowed from Marc Rose).
Personal attacks or ad hominem (not insult) only allowed for “pointing out the mistake of the author of the OP or a post” purpose only, similarly ad hominem on religion (not insulating religion) is also allowed for “pointing out mistake of the author of the OP or a post” purpose only. Any unauthorized (which is not allowed by PSSR) use of ad-hominem or any kind of insult will be deleted and the poster being warned.
Ivsk2.0 is a closed group, and all its contents are the collective property of the members as a group. All members are required to not to take any OP or the comments out of the group without the authorization of the owner of the OP or the comment and may be removed for such offense under Creative Commons Attribution-NonCommercial-NoDerivs 3.0 Unported License. In case a member is removed from the group they will be given a copy of all their OPs and comments on demand in all circumstances possible. To ensure this the members are required not to block any of the admin, however for personal reason any member can block other member, but if any blocked member wanted to debate (only) the blocker member, the blocker member will be asked only to unblock the blocked one and debate, however it is the choice of the blocker to whether or not unblock.
Any member inactive or non contributing members who were found being non contributing or inactive for more that 15 days may be removed for being inactive or non contributing the group 48 hours after being informed, these members will be requested to rejoin when they think they would/could become active or contribute.
A report is filed and published on the group wall by any admin when a member is removed. The report may contain all possible aspect of their behavior, conduct and response to different condition/circumstances while they were partaking in discussion, debate or sharing their views. If the member was inactive the report will say “inactive status”. The reports which are filed will decide whether or not the member is welcomed after they are removed i.e.
- if a member has blocked admin, they will not be allowed back unless they unblock the admin.
- if a member has taken the group content (which is the property of the group members), they will not be allowed back unless the contents are taken down or removed or granted permission by the authors/posters.
Admins of the group (their names appear on Creative Common License Page) reserves the right to change or alter the “Codes of Practice” whether on public demand or by considering evolution of the group.
A link of the PSSR (Personal Safety & Social Responsibility) for online group (ivsk2.0 closed group) will be shared with any new requests received and on their acknowledgement (see section 4.0) they will be allowed access to the group contents.
Any behavior leading to the adverse effect due to the highly observable phenomenon mentioned (see abstract) might require the person responsible to apologize and the post where it occurred would be deleted after a copy of the post to be deleted will be emailed to the author/poster for their personal use.
Disciplinary procedures (under develop) will decide how the members founds not complying with the pssr will be treated or fixed.

4.0 Acknowledgement

As an author/poster/member/admin on the facebook group ivsk2.0 you mean no harm by any standard to other members, you are entitled to practice freely any of your rights without breaching any Codes of practice (see section 3.0) and you authorize admins to discipline you anytime when proved guilty of breaching the codes and not complying the responsibilities, unless not apologizes (as mentioned in section IX of 3.0 i.e. if applicable you have to apologies).

4.1 Procedure (for admins)

Any member found not not complying as acknowledged in the 'section 4.0' of the pssr may be disciplined, which possibly leading to the removal from the group.

NDT_ Dye Panetrant Testing

2012-04-20T17:25:00.000-07:00

Introduction

This blog demonstrate us the Non Destructive testing which is done in many industries where the test piece is costly or cannot be afforded to be thrown away. NDT test involves use of a dye penetrate over a test material, which by the explained procedure exposes the surface cracks.

Objective

To test the specimen for any surface cracks from a production line using dye penetrate Non Destructive test.

Apparatus

· Cleaning solvent
· Dye penetrant
· Developer
· Material= mild steel

Safety Procedure

· We have to make sure the ventilation is sufficient, as we are dealing with toxic chemical, ideally we have to wear safety masks but the chemical used in workshop were no damaging so while performing the experiment in workshop we can only consider the ventilation.

· The chemicals are reactive; they can also react with the skin and damage it, so we have to wear gloves so that our skin is protected.

· While mishandling there is a reasonable chance that we can drop or spill some amount of the chemical and they can easily penetrate our normal clothing , so ideally one must be wearing boiler suit in order to avoid the risk, but in the workshop we have very less toxic chemicals so it we were not exposed to the risk and so we neglected it.

Procedure

Clean the specimen; make sure it is nice and clean. Heat the material so that it will expand and prevail the faults and apply the dye penetrant, allow it to soak in to the cracks or faults, allow it suitable time to cool. As soon as the suitable time is elapsed, clean the material using the cleaning solvent, apply it on top of the specimen, the applied dye will make a solution with it, clean it using a rag and make sure there is no contamination left on the surface [make sure that the dye penetrant which is seeped into the cracks are not removed]. Then we apply the developer, and wait to cool down, which will allow the material to contract, and the time for developer to react with the dye. After the suitable time is elapsed the cracks will become visible.

Result

As the suitable time is elapsed for the material to contract and the developer to react the cracks or fault on the surface of the material is visible. We know the exact location of the cracks/faults on our work piece, which were 3 circles.

Conclusion

Dye Pernetrant NDT is a cost effective test, which is used by small industry for quality purposes, this allows us to demonstrate the non visible faults on the surface of material which may result in drop of efficiency in the finished product, so either the specimen is resent to the production line, if it is fix able, or scraped, if not fixable.
