You need to sketch shear force and bending moment diagrams and estimate maximum bending and shear stresses acting on the beam using your knowledge in beam analysis.
Please note that this beam problem is statically indeterminate. However, you can solve this problem using manual methods. Also write standard second order differential equation for elastic curve for the deflection of beam AB and deduce an equation for beam deflection. (Take E=200 GPa)
Perform a 2D FEA (Beam analysis) and compare FEA results and manually determined values for reactions at A and B and the deflection at mid-point of the beam.
Compare your FEA results with manually calculated values.
