In the figure, the bar AB weighs 150 N/m and is supported by a cable AC and a pin at B. Determine the reactions at B and the tension in the cable.

Find the magnitude of the pin reaction at B caused by the weight W=80lb. Neglect the weights of the members.

Two concrete blocks weighing 320 lb each form part of the retaining wall of a swimming pool. Will the blocks be in equilibrium when the pool is filled and the water exerts the line loading shown?

The 350-lb homogeneous plate has the shape of an isosceles triangle. The plate is supported by a thrust hinge at A, a slider hinge at B, and the cable CD. Find the force in the cable and the magnitudes of the hinge reactions.

The uniform, 20-kg bar is placed between two vertical surfaces. Assuming sufficient friction at A to support the bar, find the magnitudes of the reactions at A and B.
