Tests extension springs to find their properties. Proves Hooke's law and the basic rules of spring design.

An optional set of additional components to extend the range of experimentation of the TE16 Stiffness of Materials and Structures Apparatus.

A bench mounting 3-point bend apparatus to allow investigations into the stiffness in bending of different materials of the same cross-section (Young's Modulus - Stiffness) and the stiffness of a single material with different cross-section geometries (Second Moment of Area - 'I' Value).
