Question:
The crate has a mass M and is subjected to a towing force P acting at an angle θ1 with the horizontal. If the coefficient of static friction is μs, determine the magnitude of P to just start the crate moving down the plane.
Given:
M = 350 kg
θ1 = 20 deg
θ2 = 10 deg
μs = 0.5
g = 9.81m/s2

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.
