# Unknown Two Forces

## Problem 271 | Resultant of Non-Concurrent Force System

**Problem 271**

The three forces in Fig. P-270 create a vertical resultant acting through point A. If T is known to be 361 lb, compute the values of F and P.

## Problem 270 | Resultant of Non-Concurrent Force System

**Problem 270**

The three forces shown in Fig. P-270 are required to cause a horizontal resultant acting through point A. If F = 316 lb, determine the values of P and T. Hint: Apply M_{R} = ΣM_{B} to determine R, then M_{R} = ΣM_{C} to find P, and finally M_{R} = ΣM_{D} or R_{y} = ΣY to compute T.

## 242 Finding the unknown two forces with given resultant

**Problem 242**

Find the value of P and F so that the four forces shown in Fig. P-242 produce an upward resultant of 300 lb acting at 4 ft from the left end of the bar.
