I have a cane with non-uniform density and I'm trying to find its moment of inertia. There is no equation for its mass/density vs. length. If you need to picture it, it's a folding White Cane used by the blind. https://www.amazon.com/Blind-Cane-disigned-visually-convenience/dp/B000VB0CG0 I found the center of mass in a crude way by just trying to balance it. The axis of rotation should be about 12 cm down from the handle, or 126.5 cm from the bottom, since this is where it is often held. I was wondering if anyone could help me find its moment of inertia at this axis. Cane Length: 138.5 cm Center of Mass: 63.5 cm from the handle, 75 cm from the bottom Cane Weight: 255.15 grams I am also trying to find the moment of inertia when a device weighing 230 grams is attached 30 cm from the top of the cane. The center of mass of the entire apparatus when the device is added is 50 cm from the handle of the cane and 88.5 from the bottom.
