Typically, the center of mass of a solid block is in the middle of the block. Placed on an inclined plane a block tips over when its COM is no longer over its base.
Take a block that is resting on a plane. The block is 2.24 cm wide in x, 1.55 cm wide in y, and 5.09 cm tall. If we tilt it along the x-axis, at what angle does the block fall over?
