    If a beam of lenght L is fixed at the ends and loaded in the centre of the beam by a point load of F newtons the deflection at a distance x from one end is given by :

    y= (F/ 48Ei)(3L^2x-4x^3)

    Find the position and the value of the maximum deflection of the beam if;
    L = 10 m
    Ei= 300x10^6 Nm^2
    F= 100kN

    Solution. If L = 10 m , Ei= 300x10^6 Nm^2 , F= 100kN , then
    y= (F/ 48Ei)(3L^2x-4x^3)
    =(300x-4x^3)/144000 ..................(1)
    In oder to find the ...
