A simply supported beam has a span of 4.50 m. the beam is subjected to an axial tensile force of 300 kn and a vertical concentrated load p acting at midspan. the member is fully laterally supported for its entire length. the length of any bolt holes can be neglecte
d. the beam consists of 2-150 mm x 90 mm x 12 mm angles, with long legs back-to-back and spaced 10 mm apart. for this problem, the relevant properties of one 150 mm x 90 mm x 12 mm angle are. a
