Union Gas Engine: Historical Arrangement and Ideal Power Comparison
Explore a generic cylinder mechanism alongside Union engine references. Compare indicated power with a fixed 85 percent mechanical-efficiency assumption; no historical engine rating is predicted.
Prony-Brake Rule: Perpendicular Force-Arm Ledger
Measure shaft power with a Prony brake — how the friction dynamometer works, the torque formula, worked example, and design tradeoffs for engine test cells.
Friction Machine: Torque-Arm Brake Power Calculator | FIRGELLI
Calculate Prony-style brake torque and absorbed power from net perpendicular force, arm length and RPM. Keep torque-arm and rope-brake geometry separate.
