The true strain rate is given as ϒ, and conventional strain rate is given as ε. The engineering strain is equal to e. The relationship between conventional strain rate and true strain rate is _______

The true strain rate is given as ϒ, and conventional strain rate is given as ε. The engineering strain is equal to e. The relationship between conventional strain rate and true strain rate is _______ Correct Answer ϒ = ε/(1+e)

The conventional strain rate is defined by taking the initial length of specimen whereas the true strain rate takes instantaneous length into the calculation. So the relationship between them is: True strain rate = Conventional strain rate / (1+Engineering strain).

From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements:
P. The engineering stress-strain curves in tension and compression are identical.
Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect.
R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve.

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.
What is the relationship between engineering stress and true stress? Given that; s = engineering stress, σ = true stress, e = engineering strain, ε = true strain. d) σ = se+1
How is permaculture farming different from conventional chemical farming? 1. Permaculture farming discourages monocultural practices but in conventional chemical farming, monoculture practices are predominant. 2. Conventional chemical farming can cause an increase in soil salinity but the occurrence of such phenomenon is not observed in permaculture farming. 3. Conventional chemical farming is easily possible in semi-arid regions but permaculture farming is not so easily possible in such regions. 4. Practice of mulching is very important in permaculture farming but not necessarily so conventional chemical farming Select the correct answer using the code given below.

Given below are two statements: Statement I: IITs are different from other normal engineering colleges in our country. Statement II: In IITs science of engineering is taught whereas in normal engineering colleges mostly the technical aspect of engineering is taught. In the light of the above statements, choose the most appropriate answer from the options given below:
Assertion (A): When there is an evidence of a linear relationship between two variables, it may not always mean an independent-dependent relationship between the two variables.
Reason (R): The casual relationship between the two variables may not imply a reasonable theoretical relationship between the two.
