Locate the centroid y¯ of the cross-sectional area of the beam constructed from a channel and a plate. assume all corners are square and neglect the size of the weld at a. take a = 345 mm , b = 370 mm

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

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.

The proportional limit is always greater than the yield strength for a material. a)-trune b)- false
