A simple example on Maxwell’s reciprocal theorem

A 800 mm long cantilever with a prop at 500 mm from the fixed end deflects in accordance with the following observations when a point load of 40 kN is applied at its free end.(fig 1)

Distance from fixed end(mm)0100200300400500600700800
Deflection(mm)00.31.42.51.90-2.3-4.8-10.6
Determine the deflection of the free end due to a 30 kN at 200 mm from the fixed end together with a 10 kN load at 300 mm from the fixed end.(fig 2). Find also the angular rotation of the member at the prop?

Watch the video for detailed explanation for the above problem.
