A non-uniform bar rests across two supports that are 20 ft apart. When loads of 200 lb, 4 ft from end A and 150 lb, 6 ft from end B, are on the bar, end A supports 233 lb and end B supports 197 lb. Find the weight of the bar and the position of the center of gravity.

Draw the FBDs for the following system with its distributed loads simplified to their equivalentloads. Draw the FBD where the system is the bar.  You can find the system in the image provided below.

The handle of a small hand pump is 850mm long. The fulcrum is attached at one end and the load plunger is located 50 mm from the fulcrum. An effort of 600N is applied downward at the opposite end from the fulcrum. Find the force exerted by the load plunger and the mechanical advantage of the lever.
