SUMMARY
A Prony brake is an effective tool for measuring horsepower (HP) when properly constructed and utilized. In this discussion, a DIY Prony brake was built using wood, featuring a 1-foot arm, which successfully measured 0.75 HP at 180 RPM with a 22-pound weight. The shaft diameter of 2 inches is relevant, as it influences torque calculations. Accurate power measurement relies on ensuring that all torque is counteracted by the weights and arm, along with adequate heat dissipation during operation.
