A torque wrench measures the rotational force required to tighten a threaded fastener. Torque settings are often given in ft-lbs or in Nm. What parameters are involved in measuring torque?
- A Vacuum and current
- B Length and force
- C Pressure and voltage
- D Luminance and pH
That's Correct!
It's Wrong!
To measure torque, two parameters are involved: length and force. Length refers to the distance from the axis of rotation to the point where the force is applied, while force represents the amount of rotational force being applied to the fastener. By multiplying these two parameters, torque can be calculated. Vacuum and current, pressure and voltage, and luminance and pH are not relevant parameters for measuring torque.
