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 45 N·m. Using the data in the drawing, determine the magnitude F of the force that you must exert on the wrench.
Lenght of the wrench is .28 m and the angle is 50 Degrees... I get 250 for the Force but it is not right...
