Tilting

An object at rest on a surface is acted on by a force that turns it clockwise or anticlockwise about a point.The moment = force × perpendicular distance from the pivot.For tilting to occur

F d > W b

This means that the minimum horizontal force (F) required to just start tilting a uniform block of weight W with width w and height h, when pushed at the very top, is F = W×(w÷2h), because b = w/2 and d = h.If you push lower on the block, a higher force is required.
