[mike168]

Homework Statement

If I were required to draw frictional force and driving force on wheels (to scale) of cars under the following conditions, would they make any differences:
1. Front wheel drive
2. Rear wheel drive
3. All wheel drive
Assume no slipping.

Homework Equations

nil

The Attempt at a Solution

1. Frictional force only on front wheels, opposite to direction of motion, driving force opposite to frictional force
2. Frictional force only on rear wheels, opposite to direction of motion, driving force opposite to frictional force
3. Frictional force on all wheels, opposite to direction of motion, driving force opposite to frictional force

I would like to offer some additional information and clarification on the topic of frictional force and driving force on wheels of cars under different drive configurations.

Firstly, it is important to understand that the frictional force and driving force on wheels are two separate forces that act on a car. Frictional force is the force that opposes the motion of the wheels, while driving force is the force that propels the car forward.

In a front wheel drive configuration, the engine's power is transmitted to the front wheels, which are responsible for both steering and propelling the car. The frictional force on the front wheels will be greater than the rear wheels, as they are responsible for both steering and propelling the car. However, the driving force will also be greater on the front wheels as they are the ones propelling the car forward.

In a rear wheel drive configuration, the engine's power is transmitted to the rear wheels, which are responsible for propelling the car while the front wheels are responsible for steering. In this case, the frictional force on the rear wheels will be greater than the front wheels as they are the ones propelling the car forward. The driving force will also be greater on the rear wheels as they are responsible for propelling the car forward.

In an all wheel drive configuration, the engine's power is transmitted to all four wheels, which allows for better traction and handling. In this case, the frictional force will be distributed evenly among all four wheels, while the driving force will also be evenly distributed among all four wheels.

It is important to note that these forces may vary depending on factors such as the weight distribution of the car, the road conditions, and the type of tires being used. In addition, the angle of the wheels and the coefficient of friction between the tires and the road surface can also affect the magnitude and direction of these forces.

In conclusion, while the fundamental principles of frictional force and driving force remain the same for different drive configurations, the distribution and magnitude of these forces may vary depending on the specific configuration and external factors.
