URGENT Collar A slides over the smooth vertical bar shown in the figure. The masses Wa = 10lbs and WB = 5lbs. When h = 0.12192m, the spring is unextended. When the system is in equilibrium, h = 0m. Determine the constant k of the spring. Note: The normal of the collar is 100 times its mass (that of the collar), remember that g = 32.16 ft/s2.
The 54-lb block rests on the rough surface for which the coefficient of kinetic friction is μk = 0.2. A force F=(40+s2)lb, where s is in ft, acts on the block in the direction shown. The spring is originally unstretched (s= 0) and the block is at rest. (Figure 1) Figure 1 of 1A picture shows a block laying on a horizontal surface with a spring of stiffness k equal to 20 pounds per foot attached to its right side. The other end of the spring is pressed against the wall. Force F is pushing the block to the right and downwards, at an angle of 30 degrees below the horizontal. Determine the power developed by the force the instant the block has moved s = 1.5 ft.
*8–60. Each block has a weight of 400 lb. Determine how far the force P can compress the spring until block B slips on block A. What is P for this to occur?
The 20-kg block A rests on the 2-kg pan B. Both are supported by a spring having a stiffness k of 3 N/m that is attached to the bottom of the pan and to the ground. Determine the distance d the pan should be pushed down from the equilibrium position and then released from rest so that separation of the block will take place from the surface of the pan at the instant the spring becomes unstretched. Please show complete solution with FBD.
