  1. Stiffness matrix
  2. Beam problems Note: for all problems, use a W8 x 31 rolled shape, 100 inches long (per element)
  3. Simply supported beam with distributed load
    Last time, two elements SimpD2, Ansys
    Four elements, but same length (200 in.) SimpD4, Ansys
  4. Assignment due today: Cantilever beam with two forces, Cant3, (9) | Matlab | Ansys
  5. Assignment due today: Ovrhanging beam with half uniform load, CantHalf, (15) | Matlab | Ansys
  6. Converting uniform load to nodal load Simply supported | Cantilever
  7. Simply supported beam with distributed load, two elements SimpD2 | Matlab | Ansys
  8. Triangular load, one element Cantt, Ansys
    Triangular load, two elements Cantt2, Ansys
    Triangular load, two elements, incorrect SFBEAM command Ansys
  9. Assignment due Friday, April 30: Simply supported beam 200 in. long, triangular load. Triang, Ansys only, ω 0 = 60 lb/in at center, zero at ends, use two elements
    Solution: d 2 = -0.2424 in., θ 1 = -0.3788e-02 rad, SMAX = 7272.7 psi at center.
