480-V, 60-Hz, four-pole Y-connected induction motor runs at 1735 rpm when operating at full load. Assume the friction and windage losses are 1.6 kW and core losses are 1.3 kW. The motor parameters are: R₁ = 0.05 ohm, R2 = 0.04 Ohm, X₁ = 0.18 Ohm, X2 = 0.08 Ohm, X = 0.16 Ohm. find the torque at 1735 rpm using the approximate torque-slip equation.
