A cubical block of side L rests on a fixed cylindrical drum of radius R. Find the largest value of L for which the block is stable.
The Attempt at a Solution
There is only one contact point between the cube and cylinder. There are three forces acting on the cube. The normal reaction from the cylinder, the friction and weight. The normal reaction and the friction pass through the contact point. Now how do I form the equations here?
Any help is appreciated. Thanks!
