(Ng)2=60 teeth. The power of the gear train is P = 3 kW and the input speed is np1 = 1,800 RPM. 4. In the compound gear train below, the pinions have (Np)1 = (Np)2 = 24 teeth and the gears have (Ng)1: Gear 1 and pinion 2 are on the same shaft, which means those gears have the same speed and torque. Determine the following (16 points): (a) The torque of gear 1, Tg1, in N-m (b) The output torque of the gear train, Tg2, in N-m Front View of the Gear Train Bottom View of the Gear Train (NP)2 (NG) 2 (N), (No) Exam $23
