A simply-supported beam of length 3L is subjected to the loading shown in the figure.
It is given that P = 1 N, L = 1 m and Young’s modulus E = 200 GPa. The cross-section is a square with dimension 10 mm × 10 mm. The bending stress (in Pa) at the point A located at the top surface of the beam at a distance of 1.5L from the left end is_____________ (Indicate compressive stress by a negative sign and tensile stress by a positive sign.)
