How to calculate the force of friction on an incline plane?

Description

A detailed tutorial on the solving for Friction on an Incline Plane. Step by step tutorial including several examples of how to solve for Friction on an Incline Plane for reference.

Overview

The force of friction, , can be defined as multiplied by the normal force, .

is equal to the opposing force perpindicular to the surface.  In the case of an inclined plane, the opposing force to the surface would be the perpindicular component of gravity acting on the object.  To get this component, you must complete the triangle and solve for the normal force.  Once you have the normal force you can multiply by the coefficient of friction to get the force of friction.
