Discussion:
When the angle of the ramp becomes steep enough to overcome the frictional force between the bock and the plank due to the normal force of the block. Note: A free body diagram would be a good tool to describe the forces acting on the block before and after the block starts to slide. The block will then begin to slide down the ramp. When this occurs, the angle the ramp makes with the table is know as the Angle of Repose. This angle will differ depending on the normal force of the block(ie. it's mass) being used and the differences between the two surfaces (ie. it's coefficient of static friction).
