Physics
Mechanisms: Geneva, cam, ratchet
Five ideal mechanisms turn rotation into indexing, lift, reciprocation or offset-shaft transmission. Inspect the computed displacement and speed.

Select a mechanism. Compare the output and its derivative: continuous input can create dwell or reciprocation. Ideal rigid kinematics.
Equations used in the module
Equations Geneva: β = atan2(r sin φ, 1 − r cos φ), r = sin(π/N) Cam rise: s(u) = u − sin(2πu)/(2π) Scotch yoke: x = R cos φ; Oldham: ωout = ωin
