## Simple Torque on Rigid Object

1. You are installing a new spark plug in your car, and the manual specifies that it be tightened to a torque that has a magnitude of 26 N·m. Using the data in the drawing, determine the magnitude F of the force that you must exert on the wrench.

2. Torque= Force * Lever arm length

3. The force is said to be 26 N*m, and the lever arm length is shown to be 0.28 cm in the picture.

26 N*m = F * 0.28 m
F= 26 N*m/0.28m
F= 92.86 N

## Simple Torque on Rigid Object

 Quote by IAmSparticus Is it 16.165 cm (.16165 m)?
How did you get that?

The wrench forms a right angled triangle with hypotenuse 0.28 which makes an angle of 50 with the horizontal.
