Question:
Derive the following formulas relating the load W and the force P exerted on the handle of the jack discussed in Section 8.6.
(a) P = (Wr/a) tan (θ + φ s), to raise the load;
(b) P = (Wr/a) tan (φs − θ), to lower the load if the screw is self-locking;
(c) P = (Wr/a) tan (θ − φs), to hold the load if the screw is not self-locking.

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.
