=====Beams and Bending===== ====Concepts Learned==== * Bending beams - deformation and deflection * St. Venant's principle * Affect of cross sections * Concept of a neutral axis (maybe put bending and St. Venants in the last one, make this solely about cross sections) ====Activities==== Trial some existing beams and see which one of them are better. Get students to draw the cross sections up. Design their own cross section with set materials? See which ones are the strongest.
