Q
Q: If a solid cylinder is rotated about its diameter, what is its moment of inertia?
Solution:
The moment of inertia of a solid cylinder about its diameter is I = 1/4 MR^2.
Steps: 6
Show Steps
Step 1: Understand what moment of inertia means. It is a measure of how difficult it is to change the rotation of an object.
Step 2: Identify the shape of the object. In this case, we have a solid cylinder.
Step 3: Recognize that we are rotating the cylinder about its diameter.
Step 4: Recall the formula for the moment of inertia of a solid cylinder about its diameter, which is I = 1/4 MR^2.
Step 5: In the formula, 'M' represents the mass of the cylinder and 'R' represents the radius of the cylinder.
Step 6: Substitute the values of mass and radius into the formula if needed, but the general formula is I = 1/4 MR^2.
