b. The cantilever beam shown in Figure 4 has a length L=4 m. The width (w) and depth (1) of the beam are 80 mm and 35 mm respectively. A spring of stiffness, k = 25 N/mm supports the beam at the free end. The spring is initially unstressed and is always in contact with the beam. When a load of P= 450 N drops through a height of h= 50 mm at the free end, 65% of the energy is absorbed elastically by the system consisting of the beam and spring. Take the Young's modulus of the beam as E =80x10' N/mm².

A foot bridge on a hiking trail is constructed using two timber logs each having a diameter d = 0.5 m (see figure a). The bridge is simply supported and has a length L = 4 m. The top of each log is trimmed to form the walking surface (see Fig, b)LA simplified model of the bridge is shown in Fig. g.
