what is a newton meter? a. the unit of measure on a standard torque wrench b. the force of 1 newton times the distance of 1 meter c. the number of meters that can be traversed with 1 newton d. the traditional english unit of measure for mechanical work
Answer
Brief Explanations:
- Option A: A torque wrench measures torque, and the unit of torque is the newton - meter (since torque ( \tau = r\times F ), with units of meter - newton or newton - meter). This is correct.
- Option B: The force of 1 newton times the distance of 1 meter is the definition of a joule (the unit of work/energy), not a description of what a newton - meter is in the context of a torque wrench.
- Option C: The number of meters traversed with 1 newton is not related to the definition of a newton - meter.
- Option D: The traditional English unit of mechanical work is the foot - pound, not the newton - meter.
Answer:
A. The unit of measure on a standard torque wrench
