A steel bicycle wheel (without the rubber tire) is rotating freely with an angular speed of 18.00
Question:
A steel bicycle wheel (without the rubber tire) is rotating freely with an angular speed of 18.00 rad/s. The temperature of the wheel changes from -100.0 to +300.0 oC. No net external torque acts on the wheel, and the mass of the spokes is negligible.
(a) Does the angular speed increase or decrease as the wheel heats up? Why?
(b) What is the angular speed at the higher temperature?
Step by Step Answer:
a As the wheel heats up it will expand Its radius and therefore its moment of inertia will increase ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
