х 1.5 (B). A 180 mm x 130 mm x 13 mm unequal angle section is arranged with the long leg vertical and simply supported over a span of 4 m. Determine the maximum central load which the beam can carry if the maximum stress in the section is limited to 90 MN/m². Determine also the angle of inclination of the neutral axis. Tu = 12.8 x 10-6m. Ir = 5.7 x 10-m. What will be the vertical deflection of the beam at mid-span? E = 210 GN/m². [8.73 kN, 41.6º, 7.74 mm.
