Question 1 [22 marks] Figure Q1 depicts a horizontal beam that is simply supported at points B and D, loaded with an evenly distributed load of 2 kN/m along its whole length, and two concentrated loads of 4 kN and 3 kN at each end as shown. The location of support D is "x" distance from the right end E. NB: Consider point C (the mid-point of the beam) as a point of contra-flexure Determine: 1.1 The distance "x", the position of support D 1.2 Draw the shear forces and bending moments diagram (8) (14) 4 kN mid-point 2 kN/m 2 m, B C www D 6 m 8-x X Figure: Q1 3 KN E
