Solved I want to find torque from standard power formula

25-08-2016 0183 32 But the question was how to find T Without making equation relating torque like T=p 60/ 2piN So manually solving this more than easy equation was obviously not the way to go I assumed and I am not that sure in the meantime that the OP just used this equation as a simple example and had a much more complicated equation in mind where manual solving would require...
