## Problem 260 - 261 | Resultant of Non-Concurrent Force System

**Problem 260**

The effect of a certain non-concurrent force system is defined by the following data: ΣF_{x} = +90 kN, ΣF_{y} = -60 kN, and ΣM_{O} = 360 kN·m counterclockwise. Determine the point at which the resultant intersects the x-axis.

## 251 Two forces producing a couple and a force

**Problem 251**

A vertical force P at A and another vertical force F at B in Fig. P-251 produce a resultant of 100 lb down at D and a counterclockwise couple C of 200 lb·ft. Find the magnitude and direction of forces P and F.

## 233 A force creating counterclockwise and clockwise moments

**Problem 233**

In Fig. P-231, a force P intersects the X axis at 4 ft to the right of O. If its moment about A is 170 ft·lb counterclockwise and its moment about B is 40 ft·lb clockwise, determine its y intercept.

## 232 Moment of a force about points O and B

**Problem 232**

In Fig. P-231, the moment of a certain force F is 180 ft·lb clockwise about O and 90 ft·lb counterclockwise about B. If its moment about A is zero, determine the force.
