To tighten a bolt, you push with a force of 72 N at the end of a wrench handle that is 0.26 m from the axis of the bolt.What torque are you exerting?
Multipy those two numbers for the totque, in newton-meters (N*m).
If you move your hand inward to be only 0.10 m from the bolt, find the force that you should exert to achieve the same torque.
0.10 x F = 72 x 0.26
Solve for the force, F
F = 187.2 N
To calculate the torque exerted on a bolt, you need to multiply the force applied to the bolt by the distance between the point of application of the force and the axis of rotation. In this case, the force applied to the bolt is 72 N, and the distance from the axis of the bolt to the point at which the force is applied is 0.26 m.
To calculate the torque, use the formula:
Torque = Force x Distance
Substituting the given values into the formula:
Torque = 72 N x 0.26 m
Calculating this:
Torque = 18.72 N·m
Therefore, you are exerting a torque of 18.72 N·m on the bolt.
