\text { 1. The second moment of area around axis } z-z \text { (in } m^{4} \text { ) }

\text { 2. The maximum first moment of area } Q \text { (in } \mathrm{m}^{3} \text { ) }

The maximum load (Pmax) if the maximum bending stress is not to exceed 110 MPa and the maximum shear stress is not to exceed 55 MPa [4 Marks]

. The resulting bending and shear stresses due to P max at a point located at x=0 from the external support and y = +25mm from the centroid. [4 Marks]

\text { The principal stresses } \sigma_{1} \text { and } \sigma_{2} \text { and the angle } \theta_{p} \text { at that point }

\text { The maximum shear stress } \tau_{\max } \text { and the angle } \theta_{\tau} \text { at that point }

The beam deflection at x = 2.5m.
