AI-ORGANISED INDEX
workshop · ratio
Whether you are rebuilding a gearbox, a mixer or a seedling thinner. Work it out on paper before you order the gears.
AI-ORGANISED INDEX
physics · dimensionless
For a gearbox, a quad final drive, a mower gearbox or a winch. A 3:1 reduction triples the torque and drops the speed to a third. The power stays the same, less the losses.
AI-ORGANISED INDEX
workshop · %
Friction and heat are the losses. A lower efficiency means more fuel, more electricity and more heat to shift away.
