 hi,torque= ang.accleration X moment of innertia  (Nm )       =deg/sec.sq   X  Nm2  but from above conversion,how to reach to get Nm & also if we convert deg/sec.sq into rad/sec.sq, value will be reduced by 57 times   MY QUESTION HOW TO GET .....Nmthanx in beforeJohn

 Your units are not correct.The units for polar moment of inertia are: kg*m^2The units for angular accel. are: rad/sec^2radians are not a true engineering unit so they do not enter into cancelling out. That leaves you with:(kg*m^2)/sec^2 = N*m

 Hi Fredgravin HEARTLY THANKFUL TO YOU FOR GIVING THIS VALUABLEINFORMATIONwith warm regardsJohn

 FredGarvinThe radian is an engineering unit. Degrees are not.The radian measure of an angle is defined as the arclength divided by the radius of the arc. It is thus dimensionless, and hence disappears when dimensional analysis is performed to determine the resulting units of a formula.Take care.Ed.
