I have a dynamometer to determine HP and Tq of cars and im trying to setup my software and i need the inertia of my rollers to determine Tq but i have a big flywheel that will turn 1,580 revolution per each roller revolution so its very difficult to determine inertia by calculating the mass of the rollers + mass of the flywheel + gearing multiplier etc...
Someone told me that i should be able to determine inertia by turning my roller to 2000rpm and calculate the time it decelerate from 1500rpm  500rpm Do anybody can give me this formula or the right way to determine inertia by doing that Thanks Fred
