Conveyor belt
Two drums 3 m apart joined by a belt, the left one driven by a motor at 2 rad/s (0.4 m/s at the belt). Boxes put on top are carried along.
Ferris Wheel
A motor turns a wheel; eight gondolas on free pins swing like pendulums and stay close to upright all the way round.
Walking Machine
Six legs of Jansen's type, with lengths designed for this studio, on one crank: each foot runs along a straight 0.49 m stride for almost half a turn, so the machine walks about a metre per crank turn without bobbing.
V-Twin Engine
Two pistons 90° apart on one crank pin: each stroke follows s = r cos δ + √(l² − r² sin² δ), and the momentum of the moving parts turns in a nearly steady circle.
Winch: Work and Power
A motor winds a rope onto a drum: the load rises at ωR, P = F v = mg·ωR, and the potential energy gained is the work done.
Four-Bar Linkage
A crank-rocker: the crank turns round, the rocker swings to and fro through a fixed arc.
Slider-Crank
A motor turns a crank; a connecting rod drives a piston along its cylinder: x = r cos φ + √(l² − r² sin² φ).
Gear Train with an Idler
16 → 24 → 32 teeth: the idler reverses the direction and drops out of the ratio, ω_C = ω_A·Z_A/Z_C = ω_A / 2.
