Q.5 A continuous beam ABC of various flexural rigidities (EI) is subjected to external loads as shown in Figure Q.5. The beam has a fixed support at A and roller support at B and a pin support at C. A set of support reactions measured from the experiment is tabulated as below when using different set of point loads, PAB (kN) and PBC (kN).
