    I'm trying but my calculations somewhere getting wrong.... u can use T/J=G thita/L formula for calculation of shaft twisting moment. For mild steel G is around 78 to 80 Gpa (what i have searched on net) , assuming thita= 1 degree.
    We can calculate torque required but somewhere im getting wrong answer and dnt know why .... but u can assume above data and can take some experts opinion.
    Maximum torque produced by 0.5 hp motor at 10 rpm is 356.0377 N-m.

    Have you use tis formula??? Power = 2*pi*Speed*Torque/60, Nm

    Yes And the answer i alreday mention 356.0377 N-m.
    i guess thats Maximum torque for what motor produce at selective r.p.m. without any load applied,but for dia.250 mm ,10 mm thick actual torque will be different

    max torque=356.0377 Nm
    Design Torque=Max torque*k*k(not).
    assuming k*k(not) to be 1.25, Designed Torque=445.047125 Nm

    I 'm not sure of those k,k(not) values. If I 'm wrong, please suggest me a correct answer anyone.
