Final answer:
When using a torque wrench, you should place one hand on the handle of the wrench to apply force and create torque. The torque exerted can be calculated by multiplying the force by the distance from the center of the bolt. In this case, the torque exerted is 23.1 Nm.
Step-by-step explanation:
When using a torque wrench to tighten a bolt, you should place one hand on the handle of the wrench to apply the necessary force. The torque wrench is designed to measure and apply torque, which is a measure of rotational force.
By applying force to the handle of the wrench, you create a torque around the bolt, causing it to tighten. The length of the wrench handle and the force applied perpendicular to it determine the amount of torque exerted.
For example, if you exert a force of 165 N at a distance of 0.140 m from the center of the bolt, the torque exerted can be calculated by multiplying the force by the distance:
Torque = Force x Distance = 165 N x 0.140 m = 23.1 Nm
