Abstract:

An inclined plane with a block resting on top is raised until the block begins to slide.

Important Setup Notes:

Setup and Procedure:

Basically set out an inclined plane with this block or any other block.
Use a jack stand if desired or just slowly lift the inclined plane to allow the block to begin to slide down.
One can use a protractor to measure the Angle of Repose, if desired.

Cautions, Warnings, or Safety Concerns:

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).
