//Initilization of Variables
//Flanges
b=200 //mm //Width
t=25 //mm //Thickness
D1=500 //mm //Overall Depth
t2=20 //mm //Thickness of web
d=450 //mm //Depth of web
//Calculations
//Consider,Element of Thickness "y" at Distance "dy" from N.A
//Let Bending stress "sigma_max"
//Stress on the element
//sigma=y*(D*2**-1)*sigma_max ..............(1)
//Area of Element
//A=b*dy .................................(2)
//Force on Element
//F=y*250**-1*sigma_max*b*dy
//Let M be the Moment of resistance
//M=y*250**-1*sigma_max*b*dy*y
//Moment of Resistance of top flange after simplification we gget
//M.R=2258333.3*f
//M.I of I section
I=1*12**-1*(b*D1**3-180*d**3)*10**-8
//Moment acting on section
//After simplifying we get
//M=2865833.3*f
//Percentage moment resistance
M1=2258333.3*2865833.3**-1*100
//Percentage moment resisted by web
M2=100-M1
//Result
