The simply supported queen-post trussed beam shown in
the photo is to be designed to support a uniform load of 2
kN/m. The dimensions of the structure are as shown.
Determine the force developed in member CE. Neglect
the thickness of the beam and assume the truss
members are pin connected to the beam. Also, neglect
the effect of axial compression and shear in the beam.
The cross-sectional area of each strut is 400 mm², and
for the beam /= 20(106) mm. Take E = 200 GPa.
