Assignment:
1. What pull p on the rope must the man exert in order to suspend the 500-lb crate in the deflected position shown?
2. For system of forces below determine the magnitude of force which barely prevent block W1 from sliding.
3. Compute minimum force F which barely prevent block A from sliding. Block B is connected to a rigid point by a cable.
4. If the system of forces shown are in equilibrium, Find W1.
5. Block A,B and C have weight of 50N, 25N, and 15N respectively. Determine the smallest horizontal force P that will cause impending motion. The coefficient of friction between A and B is 0.3, between B and C is 0.4 and between C and ground is 0.35.
