The engine of an automobile generates a force that causes the wheels to turn. As the wheels turn, they exert a force on the road. More specifically, the wheels push back on the road. The road pushes forward on the wheels. This forward force is the force of static friction, and is responsible for pushing the automobile forward. Using the same logic, explain how a propeller-driven airplane moves forward.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

The engine of an automobile generates a force that causes the wheels to turn. As the
wheels turn, they exert a force on the road. More specifically, the wheels push back on
the road. The road pushes forward on the wheels. This forward force is the force of static
friction, and is responsible for pushing the automobile forward. Using the same logic,
explain how a propeller-driven airplane moves forward.

Q3. Audi’s design of their R8 model is designed in order to have the engine in the rear of the car with the following schematic of their mechanical power transmission. The engine is connected to the gearbox, where gear change occurs and then a driveshaft is used to transfer an equal ratio of power balancing the rear and front wheel power output thus referring to it as an all-wheel drive. The vehicle has been modified by a customer thus resulted to no power transfer to the front wheels although the rear wheels still have the same power output. Using your knowledge, DEFINE and JUSTIFY the possible reasons of why the front drive isn’t functioning. What are the solutions to this fault?
