| File x5300 20/25 BENTLEY FLYWHEEL & CLUTCH lcc 3948 8-5-34 OFF C.10 ENGINE. L.O.P G55674. MOMENT OF INERTIA TEST. WEIGHT 'W' = 82.125 LB. LENGTH OF EACH WIRE 'l' = 13.005 FT DISTANCE BETWEEN WIRES 'd' = 1.167 FT. PERIODIC TIME 't' = 2.92 SECS. Io = W t² d² / 16 π² l = 82.125 x 2.92² x 1.167² / 16 x π² x 13.005 = .4644 Slugs ft² [CHASING STO .691] OR = 14.96 LB FT². W Bell N.B. WIRES SOLDERED ON FLYWHEEL, THEREFORE THERE WAS NO TACKLE INERTIA TO DISCOUNT. | ||
