Final answer:
Isometric Peak Torque is measured by multiplying the force applied perpendicularly to the lever arm by the length of the lever arm and the sine of the angle between them, measured in newton-meters (N·m).
Step-by-step explanation:
To measure Isometric Peak Torque, you follow a series of steps to determine the amount of torque a force generates around a pivot point. The SI unit for torque is expressed in newton-meters (N·m).
First, choose a pivot point, which will be the axis of rotation and the origin of your coordinate system. Next, measure the distance from the pivot to the point where the force is applied, known as the lever arm. You also need to determine the angle between the lever arm and the direction of the force being applied. The torque is calculated by multiplying the force applied perpendicularly to the lever arm by the length of the lever arm and the sine of the angle between them. This calculation gives you the torque relative to the pivot point.
For example, if you apply a force perpendicularly on a wrench with a force of 165 N at a distance of 0.140 m from the center of the bolt, the torque exerted is 165 N x 0.140 m x sin 90°, which equals 23.1 N·m. It is important to note that the torque is at its maximum when the force is applied at a 90-degree angle to the lever arm.
