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).

A compact self-contained bench mounting apparatus designed to allow students at all academic levels to investigate basic and advanced principles of control including control of naturally unstable systems.
