A slender rodAB, of weightW, is attached to blocksAandB, which move freely in the guidesshown. The blocks are connected by an elastic cord that passes over a pulley atC. (a) Expressthe tension in the cord in terms ofWand. (b) Determine the value offor which the tension inthe cord is equal to3W.

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

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
