How do I calculate the second moment of a solid cylinder?
Click For Summary
SUMMARY
The second moment of a solid cylinder can be calculated using integral calculus, specifically by setting up the integral in polar coordinates. The differential area element, dA, is expressed as r dr dθ, where r is the radius and θ is the angle. The limits of integration depend on the dimensions of the cylinder, particularly when considering cases where the thickness t is much smaller than the radius R or vice versa.
