Two identical specimens are strained simultaneously in the elastic region. Sample-1 was loaded slowly and allowed to achieve thermal equilibrium, while sample-2 was loaded rapidly and heat transfer was not allowed. The stress-strain curve for these for sample 2 will be represented by the curve __________

Two identical specimens are strained simultaneously in the elastic region. Sample-1 was loaded slowly and allowed to achieve thermal equilibrium, while sample-2 was loaded rapidly and heat transfer was not allowed. The stress-strain curve for these for sample 2 will be represented by the curve __________ Correct Answer A

The sample is loaded in the elastic region so that the curve will be linear, hence curve C and D not possible. Now when sample loaded is without thermal equilibrium, there will be a temperature drop in the sample so the strength and modulus of the material will increase. Hence the curve A will represent the correct curve.

A word is represented by only set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are number alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example ‘K’ can be represented by 43, 89 etc and ‘F’ can be represented by 14, 78 etc. Similarly, you have to identify the set for the word ‘SAMPLE’.  Matrix I    Matrix II   0 1 2 3 4   5 6 7 8 9 0 D L H O A 5 E P V J C 1 E B R L F 6 M T W R S 2 V Q W S J 7 A H O F R 3 G A P D M 8 Q R L A K 4 S N I K C 9 G B I N D
