Consider a single crystal of silver oriented such that a tensile stress is applied along a [001] direction. if slip occurs on a (111) plane and in a [ ¯ 1 01 ] [1¯01] direction, and is initiated at an applied tensile stress of 1.1 mpa (160 psi), compute the critical resolved shear stress.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
