I'm sorry for not being clear enough: The way I though of increasing the moment of inertia wasn't by keeping the radius constant and increasing the mass, but change the mass distribution so that the mass is concentrated away from the center of rotation.

Hi, I'm trying to find out what effect an increase in moment of inertia of a cylinder would have on slipping when the cylinder rolls down an incline. Starting with: ma=mgsin(theta)-f, where f is the friction force, which is less than or equal to µmgcos(theta), normal force times µ. We already...

No, there's just air inside, so the mass of the cavity can be neglected.

Hi, sorry for the ambiguous description, the cylinders are glued together like in your b.) illustration, in other words the flat sides are glued together. The three cylinders are actually just pipes short pipes about 20 and 8 cm in diameter and 2 mm thick, so the density of each cylinder is not...

I didn't quite understand that, sorry. I thought the parallel axis theorem only was for changing the axis of objects? All my three objects are attached at the same axis, so I didn't quite get how I use the theorem. Also, the link you sent didn't contain anything about combined objects? Thanks...

Hi, I've attached a word document with my problem since I've used the Mathtype program (sorry, I didn't quite know how to use the tools on this forum), hope you don't mind :)
