//Given
dia_out = 20 //mm- outer diameter of shaft
dia_in = 16 //mm- inner diameter of shaft
c_out = dia_out/2 //mm - outer Radius of shaft
c_in = dia_in/2 //mm - inner radius of shaft
T = 40 //N/mm -Torque in the shaft
//calculations
J = 3.14*((dia_out**4)- (dia_in**4))/32 //mm4
shear_T_max = T*c_out*(10**3)/J // The maximum torsion shear in the shaft
shear_T_min = T*c_in*(10**3)/J // The maximum torsion shear in the shaft
printf("\n The maximum shear due to torsion is %e MPa",shear_T_max)
//answer in textbook is wrong
printf("\n The minimum shear due to torsion is %0.0f MPa",shear_T_min)
