1J11.15 Tipping Block On Incline

A block is placed on an incline and the incline is raised until the block tips.

A pair of long, narrow boards are hinged together at one end. The bottom board supports an arching piece of metal that rises along the end opposite the hinge, arching gently toward the center of the boards. The upper board has a clamp that allows it to slide up and down this arc and will fix it in place at a desired angle. A protractor is fixed at the bottom of the top board. A small plumb bob on a bright yellow string fixed to the protractor allows the demonstrator to read the angle of inclination of the top board. A small wooden block sits upright on the top board. One imagines that if the angle were sharp enough, the block would tip.
