Car Flywheel Force

In summary, the size of the flywheel does not directly affect the force acting on it, but a larger flywheel may require more force to accelerate or decelerate. The force acting on the flywheel is impacted by factors such as mass, rotational speed, and external forces. It can be calculated using the formula F = ma, accounting for the flywheel's rotational speed and inertia. The shape of the flywheel does not directly impact the force, but can affect its rotational inertia. To measure the force in a car, a dynamometer can be used to measure torque and rotational speed, which can then be used to calculate the force using the aforementioned formula.

Crash? Just the force from the deceleration not actually being crushed. Thanks

You need to be more specific about the situation you are considering.
The force will be dependent on the flywheel mass, moment of inertia and the time it takes to stop.

1. How does the size of the flywheel affect the force acting on it?

The size of the flywheel does not directly affect the force acting on it. However, a larger flywheel may require more force to accelerate or decelerate due to its greater rotational inertia.

2. What factors impact the force acting on the flywheel?

The force acting on the flywheel is impacted by several factors, including the mass of the flywheel, the speed at which it is rotating, and any external forces acting on it, such as friction or air resistance.

3. How can I calculate the force acting on the flywheel?

The force acting on the flywheel can be calculated using the formula F = ma, where F is the force, m is the mass of the flywheel, and a is the acceleration. This formula can be modified to take into account the rotational speed and inertia of the flywheel.

4. Does the shape of the flywheel affect the force acting on it?

The shape of the flywheel does not directly impact the force acting on it. However, the distribution of mass within the flywheel can affect its rotational inertia, which in turn can impact the force required to accelerate or decelerate it.

5. How can I measure the force acting on the flywheel in a car?

The force acting on the flywheel in a car can be measured using a dynamometer, which is a device that measures torque and rotational speed. This data can then be used to calculate the force acting on the flywheel using the aforementioned formula.
