Two rods of zinc (c/a - 1.856) were loaded in tension to the point where plastic deformation occurred at the same critical stress level. Yielding was found to occur at different load levels, however. Examination of the 1.25-cm rods revealed them to have been oriented differently with respect to the direction of loading as noted in the following table:Rod A phi angle: 83.5, lamda angle: 18Rod B phi angle: 13, lamda angle: 78Where phi = angle between loading axis and normal to the slip planelamda = angle between loading axis and slip directiona) What is the most probable slip system for this material?b) If Rod A yielded with a load of 203 N, what would have been the load at yield for Rod B?Please post a step-by-step solution with an explanation for any assumptions and what each step signifies. Thanks!
