If the coefficient of static friction at B is ? s = 0.3, determine the largest angle
Question:
If the coefficient of static friction at B is ?s = 0.3, determine the largest angle and the minimum coefficient of static friction at A so that the roller remains self-locking, regardless of the magnitude of force P applied to the belt. Neglect the weight of the roller and neglect friction between the belt and the vertical surface.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
