# Y-Intercept of a Force

## 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.

## Resultant of Non-Concurrent Force System

The resultant of non-concurrent force system is defined according to magnitude, inclination, and position.

The magnitude of the resultant can be found as follows

$R_x = \Sigma F_x$

$R_y = \Sigma F_y$

$R = \sqrt{{R_x}^2 + {R_y}^2}$

## 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.
