# Question

In Exercise 10, due to limited work space, you must crawl under the car. The force thus cannot be applied perpendicularly to the length of the wrench. If the applied force makes a 30o angle with the length of the wrench, what is the force required to loosen the drain plug?

In Exercise The drain plug on a car’s engine has been tightened to a torque of 25 m ∙ N. If a 0.15-m-long wrench is used to change the oil.
