Two solid spheres of radius 3 in., weighing 2 lb each, are mounted at a and b on the horizontal rod a’b’, which rotates freely about the vertical with a counterclockwise angular velocity of 6 rad/s.

the spheres are held in position by a cord which is suddenly cut. knowing that the centroidal moment of inertia of the rod and pivot is iy = 0.25 lb-ft-s2, determine (a) the velocity of the spheres after they have moved to positions a’ and b’, (b) the energy lost due to the plastic impact of the spheres and the stops at a’ and b’.

calculate (a) by treating the spheres as points with the same mass while neglecting the mass of the rod and pivot.

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
