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
the position of the 4 kg collar C on the smooth rod AB is held at r=0.72 m and L=0.3 m , determine the constant angular velocity (Theta) at which the mechanism is rotating about the vertical axis. The spring with k= 219 N/m has an unstretched length of 0.4 m. Neglect the mass of the rod and the size of the collar.
Angular Velocity (Theta) (in rad/s)
Answer
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)
