Question

what are some reasons that mechanical torque wrenches should be set to their lowest value when stored? select all that apply. it prevents pre - mature wear on the spring mechanism inside. it will break the spring after not being used. it will drain the battery. it avoids spring pre - load; maintaining the calibration of the torque wrench while stored.

Explanation:

Mechanical torque wrenches have spring - based mechanisms. Setting them to the lowest value when stored prevents pre - mature wear on the spring mechanism as it avoids unnecessary stress. It also avoids spring pre - load which helps in maintaining the calibration of the torque wrench. Mechanical torque wrenches do not have batteries and setting them to the lowest value does not break the spring after non - use.

Answer:

It prevents pre - mature wear on the spring mechanism inside., It avoids spring pre - load; maintaining the calibration of the torque wrench while stored.
