Question:
Block C has a mass mc and is confined between two walls by smooth rollers. If the block rests on top of the spool of mass ms, determine the minimum cable force P needed to move the spool. The cable is wrapped around the spool's inner core the coefficients of static friction at μA and μB.
Given:
g = 9.81m/s2
mc = 50 kg
ms = 40 kg
μ A = 0.3
μ B = 0.6 r1 = 0.2 m r2 = 0.4 m

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.
