## Problem 353 | Equilibrium of Non-Concurrent Force System

**Problem 353**

The forces acting on a 1-m length of a dam are shown in Fig. P-353. The upward ground reaction varies uniformly from an intensity of p_{1} kN/m to p_{2} kN/m at B. Determine p1 and p2 and also the horizontal resistance to sliding.

## Problem 266 | Resultant of Non-Concurrent Force System

**Problem 266**

Determine the resultant of the three forces acting on the dam shown in Fig. P-266 and locate its intersection with the base AB. For good design, this intersection should occur within the middle third of the base. Does it?
