A force of 166.7 Newton must be applied at the long end of this crow bar in order to lift a 500 lb object at the short end.
Given the following data:
Moment of force can be defined as a measure of the amount of force which causes a physical object to rotate about an axis. This ultimately implies that, moment of force is a force which tends to cause the rotation of a physical object about an axis.
In Mechanics, moment of force is also referred to as a twisting force, torque, moment or rotational force. Also, it is generally considered as the rotational equivalent of a linear force.
In order to determine the amount of force that must be applied at the long end, we would use an expression for the moment about the pivot as follows:
W × b = F(a - b)
500 × 6 = F(24 - 6)
3000 = 18F
F = 3000/18
Force, F = 166.7 Newton.
