//Initilization of Variables
b=12 //cm //width of steel plates
t=1 //cm //thickness of steel plates
sigma=75 //MPa //stress
//Calculations
//The maximum Load which the plate can carry
P=b*t*10**-6*sigma*10**6 //N
//Length of weld for static loading
//size of weld is equal to thickness of plate
S=t //cm
//P=2**0.5*l*S*sigma
//After substituting values and simplifying above equation, we get,
l=((P)*(2**0.5*S*sigma)**-1) //cm
//add 1.25 to allow start and stop of weld run
L=l+1.25 //cm
//Length of weld for Dynamic loading
//The stress concentration factor for transverse fillet weld is 1.5
sigma_2=sigma*1.5**-1 //MPa //Permissible tensile stress
//P=2**0.5*l_2*S*sigma_2
//After substituting values and simplifying above equation, we get,
l_2=((P)*(2**0.5*S*sigma_2)**-1) //cm
//add 1.25 cm
l_3=l_2+1.25 //cm
//Result
printf("Length of weld for static loading = %.2f cm",L)
