Beams

In structural engineering, a beam is a component made of a variety of materials (including steel alloys, and wood) that can resist loads applied laterally to the beam axis. Members, elements, rafters, shafts, and purlins are all terms used to describe beams.

The right hand support for beam (b) prevents a change of slope but does not exert a vertical force. Each beam is made from titanium, for which Young's modulus is 106GPa and the yield stress in 780MPa.
