A uniform cylinder of length L is compressed to half of its original length. Calculate true strain and engineering strain for the cylinder.

A uniform cylinder of length L is compressed to half of its original length. Calculate true strain and engineering strain for the cylinder. Correct Answer Engineering strain = -0.5, True strain = -0.69

Initial length = L Final length = L/2 Engineering strain = /L = -1/2 = -0.5 True Strain = ln = ln(1/2)=-0.693.

In the question below, are given a passage followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Passage: Many Engineering graduates in India ends up doing anything but Engineering jobs. Some switch to entirely unrelated fields of work like Finance or Arts but most of them are unemployed. A recent survey has highlighted that among the unemployed graduates, 66% are Engineers while only 10% of the Engineering graduates do Engineering jobs. Courses of action:  I. A law must be passed banning Engineering graduates from taking up other professions. II. The Government must appoint a committee to find out the reasons for these findings. III. A law must be passed to close all Engineering Colleges with less than 5% core job placement rate.
