//Given
//Variable declaration
D=100 //Diameter in mm
R=D/2 //Radius in mm
F=5*10**3 //Shear force in N
y=40 //given distance from N.A. in mm
//Calculation
//case(i):Average shear stress
A=%pi*R**2
tau_avg=(F/A)
//case(ii):Maximum shear stress for a circular section
tau_max=(4/3*tau_avg)
//case(iii):Shear stress at a distance 40mm from N.A.
I=%pi/64*D**4
tau=((F/(3*I)*(R**2-y**2)))
//Result

printf("\n Maximum shear stress = %0.3f N/mm^2",tau_max)
printf("\n Shear stress at a distance 40mm from N.A. = %0.3f N/mm^2",tau)
