SUMMARY
The discussion focuses on calculating the bending moment of a wooden joist with a rectangular cross-section spanning 5.0 m and supporting a 30 kN load positioned 3.0 m from the right end. The joist has a depth of 150 mm and a maximum tensile strength of 12 MPa. Participants recommend using the formula M/I = sigma/y = E/R and suggest starting with a free-body diagram to determine reaction loads before proceeding with the calculations.
