Question

The 30-150 lb torque wrench is required to be stored at 30 lbs or less to prevent prolonged torque on the internal spring mechanism which could result in invalid torque measurements during operation.

• True
• False

Answer 1

It is true that storing a torque wrench at its lowest setting is necessary to avoid invalid torque measurements during operation.

Step-by-step explanation:

The statement that a 30-150 lb torque wrench is required to be stored at 30 lbs or less is true. This is because prolonging torque on the internal spring mechanism can lead to invalid torque measurements during operation. Proper storage at the lowest setting helps maintain the calibration of the torque wrench. Additionally, the mechanical advantage provided by a wrench depends on the magnitude of the applied force, its direction with respect to the wrench handle, and the distance from the nut or bolt. Torque, which is the rotational force exerted, is maximized when the force applied is perpendicular to the wrench, at which point the sin of the angle between the force and wrench is equal to one (at a 90-degree angle).
