Demonstrates the mechanical advantage of different combinations of pulleys and a simple wheel and axle.

Demonstrates the advantages and disadvantages of three popular drive systems: belt, chain and a universal coupling, using a manually rotated frame with a low friction cantilever linkage, adjustable masses and a spring to apply force.

Demonstrates the characteristics of a spur gear, bevel gear and a worm drive.

Demonstrates the relationship between centrifugal force, radius and velocity of rotating masses.
