HOPE THIS HELPS!!!
PLEASE MARK MY ANSWER AS BRAINLIEST!!!

Answer 2

A torque is required to move the machines. The torque is equal to the multiplication of applied force and its perpendicular direction from the axis of rotation. Clearly more the distance more torque can be applied by the same force as T = r x F  On account of this the handle is put near to the circumference of stone.
