//Max bending Moment
M=F*L*10**6 //N-mm

//M=sigma*b*d**2
sigma=M*6*(b*d**2)**-1 //N/mm**2

//Let W be the central concentrated Load in simply supported beam of span L1=3 m
//MAx Moment
//M1=W*L1*4**-1
//After Further simplifying we get
//M1=0.75*10**6 //N-mm

//The section has  a moment of resistance
M1=sigma*1*6**-1*b1*d1**2

//Equating it to moment of resistance we get max load W
//0.75*10**6*W=M1
//After Further simplifying we get
W=M1*(0.75*10**6)**-1

//Result
