Question: The tune-up specifications of a car call for the spark plugs to be tightened to a torque of 38Nm. You plan to tighten the plugs by pulling on the end of a 20-cm-long wrench. Because of the cramped space under the hood, you'll need to pull at an angle of 130o with respect to the wrench shaft.

Question 1: With what force must you pull?

Please show all work to determine with what force must you pull and express your answer using two significant figures.
