The cantilever beam in Figure Q3(a) carries a point load. The beam cross section is shown in Figure Q3(b). The second moment of area or the moment of inertia about its neutral axis (NA) is $$I_{\mathrm{NA}}=19.30$$ $$\times 10^6{\mathrm{mm}}^4$$. Considering section, $$a$$ - $$a$$, determine: i. the shear stress at a point $$50\mathrm{mm}$$ above the bottom of the beam. ii. the maximum shear stress of the beam.
