Engineering lesson 11: The six simple machines · Set 172 · 40 questions

Engineer's tip (Spot the six): Lever: bar on a pivot · pulley: rope over a wheel · wheel and axle: big wheel on a rod. Inclined plane: a slope · wedge: two slopes back to back · screw: a slope wrapped round a rod. Look at how it works, not what it is called.
