Consider a cantilever beam having length L=1 m, square cross-section (width = depth =0.01 m)
and Young's modulus 50 GPa. The beam is subjected to a transverse load P=1 N at the mid-span
(L/2) at the center of the cross-section. Under the small deformation theory, the transverse
deflection of the beam (in mm) at its free-end is
