The 50-kg homogeneous smooth sphere rests on the 30° incline A and bears against the smooth vertical wall B. Calculate the contact forces at A and B. B 30° | A

Find the force acting in each of the members of the truss shown below. Remember to specify if each member is in tension or compression. 6 ft - 6 ft 6 ft 500 lbs 6 ft

The 60 kg two-wheeled cart is described in the figure and parameter table below, with G indicating the location of the center of gravity. It is to be pulled so that it goes up the small step. Find the normal force on each wheel, and the magnitude and direction of the force applied at handle.

3/5 Three cables are joined at the junction ring C. De- termine the tensions in cables AC and BC caused by the weight of the 30-kg cylinder. 3/6 A block placed under the head of the claw hammer as shown greatly facilitates the extraction of the nail. If a 50-lb pull on the handle is required to pull the nail, calculate the tension T in the nail and the mag- nitude A of the force exerted by the hammer head on the block. The contacting surfaces at A are suffi- ciently rough to prevent slipping. 45 15 50 Ib 30 kg 30 |20 B Problem 3/5 Problem 3/6
