a. A cast iron lbeam has a section shown in figure Q 1. The figure is symmetrical about the axis Y-Y.
Determine the position of the mneutral axis of the axis X-X . If when subjected to a bending
moment in the plane Y-Y, the tensile stress at the bottom edgeis 24Mpa find the values of the
bending moment expressing it in kN-m and the stress at the top edge (10mks)
b. Determine the deflections at point C,D and E in the beam shown. Take E=200Gpa and
I=60x106mmm4 (12mks)
c. Determine the slope and deflection at the free end of a cantilever beam shown in figure Q 3 (a) by
Mohr’s moment area method . Take flexural rigidity (EI) as 400kNm 2.
