Beams

¢  In Statics, the concern was with the forces required to support the beam

¢  In Mechanics of Materials, the concern is with forces that are internal to the beam and therefore can deform or rupture the beam

¢ How the internal forces and moments change with loading are the design concern

¢  In order to see how these vary, it is useful to return to one of the simple reaction models from statics, a fixed end support
