A small balcony constructed of wood is supported by three identical cantilever beams (see figure). Each beam has length L, = 2.3 m, width b, and height h = 3b/2. The dimensions of the balcony floor are L, x L2, with La = 2.7 m. The design load is 6.5 kPa acting over the entire floor area. (This load accounts for all loads except the weights of the cantilever beams, which have a weight density y = 6.5 kN/m^3 --) The allowable bending stress in the cantilevers is 45 MPa
