The Gearbox Apparatus ProDynami - 1362 uses an 'H' style gear change mechanism mounted on a sturdy wall mounted frame. This Gearbox Apparatus features three forward gears and one reverse, with gears of 20, 26, 52, and 39 teeth at module 1. It includes reversible input and output shafts, protractors for angular measurement, and transparent safety guards. Load-bearing pulleys and a full weight set support hands-on velocity and torque ratio experiments.

Construction and Design
The Gearbox Apparatus ProDynami - 1362 is built on a sturdy wall mounted frame housing all gears, shafts, bearings, and levers. An 'H' style change mechanism, with gear change lever and knob, selects between gears finished to industry standard and meshing in different ratios: 20 tooth, 26 tooth, 52 tooth, and 39 tooth, at module 1, giving three forward gears and one reverse. All gears run on shafts fitted into bearings, with the changing mechanism ensuring smooth transition. Gears can be slid across each other using a lever with ball knob, and the whole gearbox can be rotated via a rotating handle attached to the side of the input pulley, which has a diameter of 脴87.5mm. Protractors are fitted on the input and output shaft pulleys, both of which can be reversed. Clear transparent guards maintain safety and visibility. Two hangers of 100g each, along with a set of slotted weights, drive the shafts via the input and output pulleys for lifting and lowering loads.
