Specification 15.1 · Paper 2
Revise: Forces for Stretching/BendingThis is why stretching, bending or compressing a spring—or another elastic object—requires more than one force. The forces must act at different places so that different parts of the object are made to move in different ways relative to one another.
Specification P2.3a · Paper 1 (Foundation), Paper 3 (Higher)
A deformation in which forces make different parts of an object change direction relative to one another, producing a curve or angle.
Revise: Stretching and compressingStretching, compressing and bending are three forms of deformation.
For bending, it is important that the forces act at different points on the object.
