Elastic failure of a material occurs, when the tensile stress equals yield strength, yield point or the elastic limit. Also, the elastic failure occurs according to maximum strain theory, when the maximum tensile strain equals (where, σ = yield strength and E = modulus of elasticity)

If the specimen is deformed plastically beyond the yield stress in one direction, e.g., tension and then after unloading it is loaded in the opposite direction, e.g., compression, it is found that the yield stress is less than the original yield stress. This dependence of yield stress on direction loading is called ____________
The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly S1: Union finance ministry announced a series of concessions to trade and industry last month. S6: Manufacturers "feel that prices of certain components may not be brought down because of the imposition of a 30 per cent duty where there was none earlier. P: Together, these will result in a loss of revenue of Rs. 100 crore to the exchequer. Q: Earlier, these were attracting customs duty varying from zero to 100 per cent.
