SUMMARY
The maximum bending moment for a simply supported beam subjected to a uniformly distributed load (UDL) of 40 kN/m occurs at the midpoint of the beam, specifically 3.5 m from the left end. The calculation method involves converting the UDL into an equivalent point load and applying the bending moment formula. The correct approach includes constructing a shear diagram to visualize the forces acting on the beam. The final value of the maximum bending moment should be expressed in kNm with one decimal place.
