Important Setup Notes:
- N/A
Setup and Procedure:
- Basically set out the incline plan with this block or any other block.
- Use a jack stand if desired or just slowly lift the incline plan to allow the block to slide.
- One can use a protractor to measure the angle of Repose, if desired.

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. The block will 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 being used and the differences between the two surfaces.
