A prismatic bar with a length L = 1 m and cross-sectional area A = 1200 mm2 is supported at the ends. The bar is then subjected to a temperature increase of ?T = 25?C. Calculate the complete state of stress acting on an inclined section rs that is cut through the bar at an angle \theta = 45?. Use E = 200 GPa and the coefficient of thermal expansion \alpha = 12 x 10-6 / ?C.

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
