Question

A 100 cm meter rule is pivoted at its middle point. If weight of 2 N is hanged from the 20 cm point, Calculate the
amount of weight required to be applied at the 80 cm mark to keep it in a balanced position.

Answer 1

Answer:

Momentum

Moment refers to a very short period of time. If you consider a see-saw, putting weights on both sides makes it to be in a balanced moment. If you put extra weight or less weight, on one hand, the see-saw is no more balanced, and this is known as the unbalanced moment.

The measure of turning effect is known as torque. The force which acts on the body of the torque is known as moment of force.

The moment formula is given by

Moment of force = F x d

Where,

F is the force applied,

d is the distance from the fixed axis,

Moment of force is expressed in newton meter (Nm).

Moment of force formula can be applied to calculate the moment of force for balanced as well as unbalanced forces.
