Question

To obtain a given moment of force for a
turning body, the force needed can be
decreased by:
Applying the force at the pivoted point
Applying the force very close to the
pivoted point
Applying the force farthest from the
pivoted point
None of the above​

Answer 1

Answer:

the moment of force is called torque.

in order to decrease the force Needed to obtain a given amount of torque,

we need to apply the force farthest from the pivot point.

This is because T=f*r

to keep T constant and f to a minimum,

r has to be large enough.

Answer 2

applying the force farthest from the pivoted point because farther from the axis lesser the force need to be applied
