A-Level Further Mechanics - Equilibrium of a Rigid Body Booklet + Answers

Calculate the moment of a force about a point

Use the result that the effect of gravity on a rigid body is equivalent to a single force acting at the centre of mass of the body, and identify the position of the centre of mass of a uniform body using considerations of symmetry

Use given information about the position of the centre of mass of a triangular lamina and other simple shapes

Determine the position of the centre of mass of a composite body by considering an equivalent system of particles

Use the principle that if a rigid body is in equilibrium under the action of coplanar forces
then the vector sum of the forces is zero and the sum of the moments of the forces about any point is zero, and the converse of this

Solve problems involving the equilibrium of a single rigid body under the action of coplanar forces, including those involving toppling or sliding.
