Question:
A crate of mass 80 kg is held in the position shown. Determine
(a) The moment produced by the weight W of the crate about E,
(b) The smallest force applied at A which creates a moment of equal magnitude and opposite sense about E,
(c) The magnitude, sense, and point of application on the bottom of the crate of the smallest vertical force which creates a moment of equal magnitude and opposite sense about E.
0.6 m--- 8.6 m- 0.5 m 0.55 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.
