Chapter 5, Problem 52P

Find the internal force system acting on section 3 for the pin-connected frame.

The cable supports three 400-lb loads as shown. If the maximum allowable tension in the cable is 900 lb, find the smallest possible sag hC at C.

The uniform bar of weight W is held in equilibrium by the couple C0. Find C0 in terms of W, L, and .

The woman is trying to move the crate of weight W by pulling on the rope at the angle to the horizontal. Find the smallest possible tension that would cause the crate to slide and the corresponding angle .

Find the forces in members CD, DH, and HI.

The homogeneous bar AB weighs 25 lb. Determine the magnitudes of the forces acting on the bar at A and B. Neglect friction.

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.

Compute the magnitudes of the reactions at pin A and the roller at D. Neglect the weight of the body.
