Question

Give one example of a machine for the use of changing the point of application of force.

Answer 1

A machine can change the point of application of force:

1. A machine can change the point of application of effort to a convenient point for ease of doing work.
2. The point at which input energy is applied is called the effort point.
3. The point at which output energy is obtained for overcoming the load is called the load point.

Example of a machine changing the point of application of force:

1. The bicycle is used for changing the point of application of force.
2. The rear wheel is connected to the pedals with the help of a chain.
3. Thus, the effort is applied on the pedals and not directly on the rear wheels to rotate it.

Hence, the bicycle is an example of a machine, used of changing the point of application of force.
