Tilting and Toppling

Unstable EquilibriumIf an object is tilted, the object will topple if the displaced centre of mass is no longer above or below the point of support or if the line of action of the weight is outside the area of contact with the surface it is resting on.The weight therefore acts to displace the object further from the equilibrium position.The object will return to its position of stable equilibrium if the displaced centre of mass is still above the point of support or if the line of action of the weight is within the area of contact with the surface it is resting on.
