Course Learning Outcomes:

  1. Draw a free-body diagram with unknown external and/or internal forces, bending moments and/or torques and apply equations of equilibrium to solve for unknown external and/or internal forces, moments and/or torques.
  2. Determine the shear force equations (diagrams) for a beam.
  3. Determine the bending moment equations (diagrams) for a beam.
  4. Calculate the 2D stress state (normal and/or shear components) at a given point from a combination of applied normal forces, shear forces, moments and/or torques.
  5. Calculate the 2D strain state (normal and/or shear components) from a known amount of deformation.
  6. Determine the torsional shear stress and angle of twist at a given location in a shaft with circular cross-section subject to applied torques.
  7. Calculate the first and/or second moments of area for a complex cross-section.
  8. Determine the slope and deflection equations for a beam.
  9. Determine the state of stress at a point at any orientation relative to a given or pre-determine state of stress using the general equations for stress transformation.
  10. Determine the state of stress at a point at any orientation relative to a given or pre-determined state of stress using a Mohr鈥檚 circle.
