The two blocks under the double wedge are brought together using a left and right square-threaded screw. if the mean diameter is 20 mm, the lead is 5 mm, and the screw coefficient of static friction, mu s, is 0.4, determine the torque needed to draw the blocks together. the coefficient of static friction between each block and its surfaces of contact is mu s 0.4 also. assume the blocks are of negligible weight.

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
