Extracted text: A 3 m long simply supported beam of uniform cross section is subjected to a uniformly distributed load of w = 20 kN/m in the central 1 %3D m as shown in the figure. w = 20KN/m El = 30 x 10° Nm 1 m- 1 m- -1 m P . Q wwww If the flexural rigidity (EI) of the beam is 30 × 106 N-m2, the maximum slope (expressed in readians) of the deformed beam is
