Also expect to lose 10% power from a 2 pulley system, maybe as much as 15% since you are gearing it up which causes higher losses. The force that needs to be exerted gets reduced when using the pulley to lift bodies. The pitch circle coincides with the pitch line of the belt while wrapped around the pulley. Conveyor Pulley Rpm Calculator Formula Related. A few simplifying assumptions were made in these calculations: the pulley was considered massless, since otherwise another force equal to the weight of the pulley would have been included in the free-body diagram, the tension in the string was considered to be vertical on the right side of the pulley even though it isn’t. The gravitational acceleration n is a constant equal to 9. As a kilogram is a measurement of mass, this should be converted to weight (Newtons) to calculate the resultant force correctly. And it may be a mongrel to start the engine with that type of load hanging off it, you may need a system to loosen the v-belt until the engine is going, then spin up the generator later.
