1000 lb trunch the black resting on the incline plan has a mass of 60g. determine maximum and minimum value of P for which the block is in equilibrium. (fs = 0.35)

Figure 1 shows a system of two blocks A weighs 1800 N and B weighs 2200 N, are lying on inclined planes. The two blocks are connected by a uniform horizontal rod of weight 800 N. Determine (a) the reaction of each block on the plane surfaces (b) the compression force of the rod on blocks A and B (c) the value of force P to impend the block A upward. Take the coefficient of friction for all the surfaces as 0.3

A uniform rod is rotating on a horizontal plane about a vertical axis through one end with a constant angular velocity ω0. Due to internal shear forces, the rod breaks at the mid-point of its length, and the part with the fixed axis has an angular velocity 1.5ω0 in the same sense. Determine the angular velocity of the other half.
