Lesson: The Equilibrium of a Body on a Rough Inclined Plane Mathematics
In this lesson, we will learn how to solve problems on the equilibrium of a body on a rough inclined plane.
A body weighing 195 N is on a rough plane that is inclined at an angle of to the horizontal. If the coefficient of friction between the body and the plane is , which of the following is true about the body?
The figure shows a body of weight 46 N resting on a rough inclined plane. Given that the body is on the point of sliding down the plane and that the coefficient of static friction is , find the magnitude of the limiting friction.
A body weighing 60 N rests on a rough plane inclined to the horizontal at an angle whose sine is . The body is pulled upward by a force of 63 N acting parallel to the line of the greatest slope. Given that the body is on the point of moving up the plane, find the coefficient of friction between the body and the plane.
