Question

state one wayto reduce the moment of a given force about a given axis of rotation

Answer 1

Hey !
Here is your answer !!

_________________


➡Moment of a force (or torque) depends on two factor :

The magnitude of the force applied and the perpendicular distance of the line of action of force from the axis of rotation.
Answer ------->
Hence by reducing the force applied or decrease the perpendicular distance of the line of action of force from the axis of rotation !

Answer 2

MOMENT OF FORCE THAT IS TORQUE IS THE TURNING EFFECT PRODUCED BY A PIVOTED BODY WHEN FORCE IS APPLIED ON IT AT A CONVENIENT POINT

SO WE SEE THE TORQUE OR MOMENT OF FORCE DEPENDS ON TWO FACTORS-

1. MAGNITUDE OF FORCE

2. PERPENDICULAR DISTANCE BETWEEN THE FORCE AND CENTRE OR PIVOTED POINT.

THEREFORE TO REDUCE THE TURNING EFFECT

WE NEED TO REDUCE THE FORCE OR THE PERPENDICULAR DISTANCE

AS TORQUE IS DIRECTLY PROPORTIONAL TO BOTH

TORQUE = F × D...

hope it helps
