# How to Calculate Torque and Equilibrium of a Lug Wrench?

As described in the given data, a lug wrench weighing 14 N is 1.0 m long from the center of the lug nut to the end of its handle. The center of gravity of the lug wrench is positioned halfway between the nut and the end of the handle. There are three forces acting on the wrench: F1, F2, and the force of gravity (not shown).

F1 = 22N and acts at a distance r1 = 0.75m from the center of the nut. F2 = 11 N and acts at the right end of the wrench. The directions of these forces are provided in the data.

The forces F1 and F2, along with the weight of the lug wrench, generate torques on the wrench. To maintain equilibrium, the sum of clockwise torques must be equal to the sum of counter-clockwise torques. This balance is crucial for ensuring stability and proper functioning of the wrench.

## Torque Calculation and Equilibrium Analysis

The torque equation, Torque = Force x Distance, is fundamental in determining the torques produced by forces on an object like a lug wrench. In this scenario, we analyze the torques created by F1, F2, and the weight of the wrench to establish equilibrium.

The lug wrench's weight of 14 N acts at the center of mass, which is positioned at the midpoint of the wrench. As the center of gravity is halfway from either side, i.e., 0.5 m, the torque due to the weight can be calculated accordingly.

For equilibrium, it is essential to balance the torques around a chosen point, such as the center of the nut. This entails ensuring that the sum of clockwise torques (generated by F1 and the weight) equals the sum of counter-clockwise torques (produced by F2).

By diligently calculating and equating these torques, we can gain a comprehensive understanding of the equilibrium condition of the lug wrench. This analysis provides insights into the intricate interplay of forces and torques that maintain stability and functionality in mechanical systems.
