Question

A door opening around a fixed hinge is an example of _________ (moment / pressure ).

Answer 1

1. A force may cause an object to turn about a pivot. This turning effect of a force is called the moment of the force.
2. The moment of the force is called torque.
3. When we open or close a door by pushing or pulling, it turns the door about its hinge or axis of rotation.
4. Therefore, the door is opened or closed due to the turning effect of force acting on it.
5. There are two types of the moment of force with respect to the direction of rotation it causes that is clockwise moment and anticlockwise moment.

Hence, A door opening around a fixed hinge is an example of a moment.
