    Φ = 3o = 52.360 x 10-3 rad, T = 9 x 103 N-m, L = 2.0 m
    Φ = TL/GJ = 2TL/πc4G
    c4 = 2TL/πGΦ based on twist angle
    τ = Tc/J = 2T/πc2
    c3 = 2T/πτ based on shearing stress
    Steel shaft: τ = 90 x 106 Pa, G = 77 x 104 Pa
    Based on twist angle
    Based on sharing stress
    Required value of d is the larger, so d = 82.1 mm
