There are three metals given below. Metal A – Very few numbers of the slip systems Metal B – High critical resolved shear stress Metal C – High number of the slip system Which of the following is more susceptible for twining? Correct Answer Metal A and Metal B

Twinning is not a dominant deformation mechanism in metals which possess many possible slip systems. Twinning generally occurs when the slip systems are restricted or when something increases the critical resolved shear stress so that the twinning stress is lower than the stress for the slip.

Which of the following factors are affecting critical shear stresses? 1. Purity of metals reduces the critical shear stress 2. Surface films greatly enhance the critical shear stress 3.

Tresca or maximum-shear stress criteria assumes that yielding occurs when the maximum shear stress reaches a value of the shear stress in the uniaxial tension test. Assume the principal stress being σ1, σ2, σ3 where σ1 is largest, and σ3 is the smallest principal stresses. Find the value of minimum shear stress to cause yielding, given that yield stress in tension is equal to σo?
Slip begins when the shearing stress on the slip plane in the slip direction reaches a threshold value called the critical resolved shear stress.

Given below are three quantities named A, B and C. Based on the given information, determine the relation among the three quantities. Total number of pupils in three classes of a school is 1288. The ratio of children in three classes X, Y, Z is 39 : 64 : 58. In class X number of boys are 26 less than number of girls. Number of boys in class Y is 67.83% more than the number of boys in class X. And, girls in class Z are 25.36% less than the number of girls in class Y. (In calculating number of boys and girls, the decimal value must be rounded off to nearest whole number). Quantity A: Number of boys in class Z. Quantity B: Number of girls in class X. Quantity C: Number of girls in class Y.
