1. The 700-N force is applied to the 100-kg block, which is stationary before the force is applied. Determine the magnitude and direction of the friction force F exerted by the horizontal surface on the block.
P = 700 N
2. The magnitude of force P is slowly increased. Does the homogeneous box of mass m slip or tip first? State the value of P which would cause each occur- rence. Neglect any effect of the size of the small feet.
A closed, frictionless, piston-cylinder assembly contains 4 lbm of H20. Beginning with an initial volume of 10 ft^3, the H2O is compressed slowly until the volume has been reduced to 10 percent of the initial volume. During the process, heat transfer..
