For some metal alloys, a true stress of 345 mpa produces a plastic true strain of 0.02. how much will this alloy elongate when a true tress of 415 mpa is applied if the original length is 500 mm? the value of strain-hardening exponent, n = 0.22.

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.
