A steel girder of length l rests freely on two supports (figure). The moment of inertia of its cross-section is equal to I (see the foregoing problem). Neglecting the mass of the girder and assuming the sagging to be slight, find the deflection lambda due to the force F applied to the middle of the girder. |

Answer» Solution :ONE can THINK of it as analogous to the previous case but with a BEAM of length `l//2` loaded UPWARD by a force `F//2`. THUS `lambda=(Fl^3)/(48EI)`, On using the last result of the previous problem.
