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?
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
Given that:
The torque from the combustion engine is .
The torque from the electrical car engine is
The diameter of both tires is .
It is required to determine the force applied on the road by the car.
