⚙️ Flat Belt Drive: Capstan Law, Wrap Angle, Slip and Power Limit (2D)

Side view of a leather belt that carries power from a driver pulley on a mill line shaft to a driven pulley. Change the pulley sizes, the shaft speed, the centre distance, the friction and the belt tension and watch the tight and slack sides, the slip and the power the belt can carry before it slides. The capstan law, the belt geometry, the best belt speed and the slip equilibrium are checked numerically, with four in-page numerical checks.
