How to Measure Torque Using a Pipe Wrench

Torque is the force exerted on an object that causes he object to turn or twist. It becomes very important in industrial applications to measure this force as a means of evaluating the maximum tolerances of various components such as drive shafts and wheel lug nuts. One simple way of measuring torque involves a pipe wrench fastened to a shaft in conjunction with a spring scale.

Instructions

1

Tighten the jaws of a 12-inch pipe wrench around the shaft or pipe on which you wish to measure torque.

2

Attach the weight-end hook of a spring scale to the hole in the end of the pipe wrench.

3

Pull on the other end of the scale at a right angle to the wrench and the shaft.

4

Note the reading on the scale in pounds.

5

Multiply this weight value by the length of the wrench (one foot, or 12 inches).

6

Express your answer in foot-pounds. If the scale reads 50 pounds, multiply 50 pounds by one foot. Your torque is 50 foot-pounds.

7

Express your answer in inch-pounds. If the scale reads 50 pounds, multiply 50 pounds by 12 inches. Your torque is 600 inch-pounds.
