A mechanics problem

Find minimum force 'F' required to keep rod BC horizontal. The length of rod AB,BC and CD is 'l' and the length of the ceiling illustrated as AD is twice of 'l'. The block of mass 'M' is connected to the junction 'B' by means of a light and inextensible spring. Assume the masses of the rods to be negligible.
