A uniform plank AB AB\,AB of length 6 m and mass 40 kg rests horizontally on two supports at C C\,C and DDD, where AC=1.5AC = 1.5AC=1.5 m and AD=4AD = 4AD=4 m.

A man of mass 80 kg stands on the plank at a distance y y\,y m from AAA.

Find the set of possible values of y y\,y for which the plank remains in equilibrium.
