A wooden cantilever 2 m long having a rectangu-
lar cross-section 120 x 200 mm² is loaded by a concentrated force of 2.5
kN at the free end. The load lies in the transverse plane of the beam and
passes through its centre of gravity as shown in Fig. 9.23. Calculate the
normal stress along the sides of the fixed end and the deflection of the
free end of the beam, E = 10 GPa.
