Lesson: The Equilibrium of a Body on a Rough Horizontal Plane

Given that the coefficient of static friction between a body and a plane is , what is the angle of friction? Round your answer to the nearest minute if necessary.

A body weighing 25.5 N rests on a rough horizontal plane. A horizontal force acts on the body causing it to be on the point of moving. Given that the coefficient of friction between the body and the plane is , determine magnitude of the force.

A body weighing 8.5 newtons rests on a rough horizontal plane. A horizontal force is acting on it causing it to be on the point of moving. Given that the force of the friction was 3.4 newtons, find the coefficient of static friction.
