The torque, T(N.m), required to rotate shafts of different diameters, D(mm), on a machine is shown in the table below. If the low is: T = aD" where a and n are constants. Determine the constants a and n to give the best fit to following data: D (тm) | 7.0 T (N.m)| 0.974 Then standard deviation (S,) about the mean. 25 40 15.3 10 18 1.71 4.33 7.28
