Study Notes

Force Components

The horizontal component of a force along the x-axis is represented by the formula Fx.

Concurrent Force Systems

In a concurrent force system, the lines of action of all forces meet at a single point.

Resultant Force

The formula $R = \sqrt{\sum F_x^2 + \sum F_y^2}$ represents the magnitude of the resultant force.

Resultant in Non-Concurrent Force System

The formula for the resultant of a non-concurrent force system in the y-direction is Fy.

Resultant Quadrant

If the sum of forces in the x-direction is positive (∑Fx = +) and the sum of forces in the y-direction is negative (∑Fy = -), the resultant force lies in the 4th quadrant.
