![4.4 (A/B). A horizontal steel girder has a span of 3 m and is built-in at the left-hand end and freely supported at
the other end. It carries a uniformly distributed load of 30 kN/m over the whole span, together with a single
concentrated load of 20 kN at a point 2 m from the left-hand end. The supporting conditions are such that the
reaction at the left-hand end is 65 kN.
(a) Determine the bending moment at the left-hand end and draw the B.M. diagram.
(b) Give the value of the maximum bending moment.
(c) If the girder is 200 mm deep and has a second moment of area of 40 × 10-6 m* determine the maximum stress
resulting from bending.
