A 2.0m rectangular uniform slab of concrete is supported on 7 cylindrical rollers. If the slab is pushed to the right, how far can it move before it's center of gravity is to the right of the 7th roller, at which point it tips?

It is clear from the given figure that initially the CoG of the slab is resting on the middle roller.
As the slab is moved towards the right side, so long its CoG rests on any of the cylinders it will stay in the balanced condition. When it just crosses the right most cylinder, it will tip.

In such an eventuality the maximum distance moved by the slab towards right before it tips is #=2.0/2=1\ m#
