Problem 7.05. A typical internal combustion engine vehicle can provide roughly 170. ft- lbs of torque (often less, depends on gearing and engine revs) while a typical electric car can provide 300. ft-lbs of torque (instantaneously). If both cars have tires which are 60.0 inches in diameter total, how much force (in Newtons) does each car apply to the road?
