Ball a is thrown straight up with an initial speed v0 and reaches a maximum elevation h before falling back down. when a reaches its maximum elevation, a second ball is thrown straight upward with the same initial speed v0. at what height, y, will the balls cross paths? a. y = hb. y > h/2c. y = h/2d. y < h/2e. y =0

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

What is creep? what is stress relaxation?

Aseries piping system conveys methyl alcohol. the system consists of 70 m of 1- nominal pipe follow by 50 m of 2-nominal pipe, both schedule 40 commercial steel. the 1-nominal pipe contains 3 90° elbows (regular) anda fully open gate valve, all threaded. the pressure drop through the system is 150 kpa. determine the volume flow rate through the system that is horizontally laid.
