Question

Give an example of an appliance that works on the principle of moment.

Answer 1

Example of the principle of the moment:

1. According to the principle of the moment, if the body is balanced, the total clockwise moment about a point is equal to the total anticlockwise moment about the same point.
2. If $F$ is the product of force and $r$ is the perpendicular distance from a given pivot, then the moment of force is given as,

Moment $=F\times r$

3. An appliance that works on the principle of the moment is beam balance to measure the weight of an object by comparing it to the standard weighing scales.

Hence, an example of an appliance that works on the principle of the moment is a beam balance.
