Calculating Force on Pillars: A Physics Moment Question

[jisaac]

Hi,
ii was just wonderin how to work out the force exerted on two separate pillars with a beam of 120kg resting on top of them
thanks

So basically it is the 120kg beam resting on top of 2 more or less fulcrums?
the weight of the beam acts downwards and the normal reactions of the pillars on the beam act vertically upwards...
