A beam consists of a symmetrically rolled steel joist. The beam is simply supported at its ends and carries a point load at the centre of the span. If the maximum stress due to bending is 140 N/mm, find the ratio of the depth of the section to span in order the central deflection may not exceed of 1 480 the span. Take E = 2 105 N/mm. 7 125 (a) (c) 9 125 (b) (d) 6 84 61 84 A beam consists of a symmetrically rolled steel joist.
