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
