i have to make a compound machine out of all six simple machines...can anyone help???

Question

physics...plz plz plz help

Answer 1

Simple machines are
1. Lever
2. Wheel and axle
3. Pulley
4. Wedge
5. Screw
6. Inclined Plane

A crazy machine

A block on wheels of mass m is placed on the inclined plane. A rope is attached to the block at the end which faces the inclined plane and thrown over a pulley. The other end of the rope is connected to a longer arm of the lever. A wedge is driven between the shorter arm of the lever and some rigid support. The lever is driven by a screw.

This contraption used all 6 simple machines and will allow a block to be precisely positioned on the inclined plane. A bit crazy but it is a solution.
