the force (in pound) you must exert on a wrench handle to loosen a bolt on a bike varies inversely as the length L (in inches) of the handle. A force of 30 pounds is needed when the handle is 8 inches long. a. find an equaion that describe the relation between handles lenght and force.  b. if you use a 5 inch long wrench to loosen the bolt, how much force do you need to apply to the handle?
