Why it is option C? Give the clear explanation.

Pranjal said:   10 years ago
B can also be correct by substituting the value of I, please tell me.

Deflection simply supported beam carrying point load at its mid point=wl^3/48EI.

Right @Mr. Asif.

Deflection is always inversely proportional to the moment of inertia in any case of loading.

I = bd^3 /12.
