Beam on two supports: shear force & bending moment diagrams
Application of the method of sections to determine internal reactions of the beam
Features
- application of the method of sections to determine internal reactions of the beam
- direct indication of shear force and bending moment at a section on the beam
Learning objectives/experiments
- calculation of the reactions arising from the static conditions of equilibrium
- application of the method of sections to calculate the internal forces and moments
-- under a point load
-- under multiple point loads
- calculation of the shear force diagram
- calculation of the bending moment diagram
- comparison of calculated and measured values for shear force and bending moment
