The uniform rod having a weight W and length / is supported at its ends A and B by two identical supports as shown in Figure below. As the end B is lifted it is observed that the rod is on the verge of slipping when e = 30°. Determine the coefficient of static friction Hs at A and B. Neglect the thickness of the rod for the calculation. B e =30°
