# What is the resultant of a pair of 1-pound forces at right angles to each other?

## Question:

What is the resultant of a pair of {eq}1- {/eq}pound forces at right angles to each other?

## Resultant Force:

Resultant force is the combination of all the forces acting upon an object. Commonly, the resultant force is computed by using the equation below:

{eq}R = \sqrt{(\Sigma f_x)^2+(\Sigma f_y)^2} {/eq}

Where:

• {eq}R {/eq} is the resultant force
• {eq}\Sigma f_x {/eq} is the summation of the forces in the x-axis
• {eq}\Sigma f_y {/eq} is the summation of the forces in the y-axis

Let:

• the first force be {eq}f_1 = 1\angle{0^{\circ}} {/eq}
• the first force be {eq}f_2 = 1\angle{90^{\circ}} {/eq}
• the resultant force be...
