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 10mm 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.)
