//Variable Declaration
L=1.5 //Length of the shaft in m
t_B=200 //Torque per unit length in N.m/m
d=0.025 //Diameter of the shaft in m
G=80*10**9 //Bulk Modulus for steel in Pa
//Calculations
//Part(1)
//After carrying out the variable integration
T_A=0.5*t_B*L //Torque about point A in N.m
//Using equation of max stress
tau_Max=(16*T_A)*(%pi*d**3)**-1 //Maximum stress in the shaft in Pa
//Part(2)
J=(%pi*d**4)*32**-1 //Polar moment of inertia in m^4
//After carrying out the computation for angle of twist we get
theta_r=(t_B*L**2)*(3*G*J)**-1 //Angle of twist in radians
theta=theta_r*(180*%pi**-1) //Angle of twist in degrees
//Result
