# resultant of parallel forces

## 243 Finding the magnitude and position of the missing force

**Problem 243**

The resultant of three parallel loads (one is missing in Fig. P-243) is 13.6 kg acting up at 3 m to the right of A. Compute the magnitude and position of the missing load.

## 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.

## 241 Finding the resultant of vertical forces acting on the Fink truss

**Problem 241**

Locate the amount and position of the resultant of the loads acting on the Fink truss in Fig. P-241.

## 237 Finding the resultant of parallel forces acting on both sides of the rocker arm

**Problem 237**

Determine the resultant of the four parallel forces acting on the rocker arm of Fig. P-237.

## 236 Computation of the resultant of parallel forces acting on the lever

**Problem 236**

A parallel force system acts on the lever shown in Fig. P-236. Determine the magnitude and position of the resultant.
