Rotational motion of a cylinder

In summary, the conversation discussed the concept of precession, which is a force that causes a cylinder or object to stand up and spin on one of its ends when a torque is applied. This motion is similar to spinning a coin on a table and can also be seen when riding a bicycle. Precession is also the main principle in a gyroscope. The person in the conversation was looking for more information on this type of motion.

ok I am not sure what this kind of motion is called but it is caused when a cylinder, a AA battery let's say, is liying on a flat smooth surface and a torque is applied to one end which causes the battery to stand up and spin on one of its ends. I've been looking for a name or a few details about this motion, i want to do a little research.

thanks in advance. - Tyson

im fairly certain its the same motion as when you spin a coin on a table.

Hi there!
The force that govern what you are saying is called precession. Precession can be seen when you ride a bicycle. It is this precession force that keeps you standing on 2 wheels. I don't know much about the principle of precession. But precession is the main character in a gyroscope.
Thanks
 

FAQ: Rotational motion of a cylinder

1. What is rotational motion of a cylinder?

Rotational motion of a cylinder refers to the circular movement of a cylinder around its axis. It can occur when a force is applied to the cylinder, causing it to rotate.

2. What factors affect the rotational motion of a cylinder?

The factors that affect rotational motion of a cylinder include the mass and shape of the cylinder, the force applied to it, and the surface it is rolling on.

3. How is rotational motion of a cylinder different from translational motion?

Rotational motion involves circular movement around an axis, while translational motion involves movement in a straight line. In rotational motion, all points on the cylinder move at the same angular velocity, while in translational motion, all points move at the same linear velocity.

4. What is the moment of inertia in rotational motion of a cylinder?

The moment of inertia in rotational motion of a cylinder is a measure of how difficult it is to change the rotational motion of the cylinder. It depends on the mass and distribution of mass of the cylinder. A cylinder with more mass concentrated towards its edges will have a higher moment of inertia.

5. How is rotational motion of a cylinder used in real life?

Rotational motion of a cylinder is used in various real-life applications, such as in engines, turbines, and wheels. It is also used in sports equipment like baseball bats and roller skates. Understanding the principles of rotational motion is essential in designing and improving these types of objects.
