## Problem 346 | Equilibrium of Non-Concurrent Force System

**Problem 346**

A boom AB is supported in a horizontal position by a hinge A and a cable which runs from C over a small pulley at D as shown in Fig. P-346. Compute the tension T in the cable and the horizontal and vertical components of the reaction at A. Neglect the size of the pulley at D.

## Problem 338 | Equilibrium of Parallel Force System

**Problem 338**

The two 12-ft beams shown in Fig. 3-16 are to be moved horizontally with respect to each other and load P shifted to a new position on CD so that all three reactions are equal. How far apart will R_{2} and R_{3} then be? How far will P be from D?

## Problem 337 | Equilibrium of Parallel Force System

**Problem 337**

The upper beam in Fig. P-337 is supported at D and a roller at C which separates the upper and lower beams. Determine the values of the reactions at A, B, C, and D. Neglect the weight of the beams.
