Question
A small balcony constructed of wood is supported by three identical cantilever beams (see figure). Each 56 beam has length L1 = 2.3 m, width b, and height h = . The dimensions of the balcony floor are L1 × L2, with L2 = 2.6 m. The design load is 6.5 kPa acting over the entire floor area. (This load kN accounts for all loads except the weights of the cantilever beams, which have a weight density y = 6.5 m3 .) The allowable bending stress in the cantilevers is 29 MPa. 56 L2 (a) Assuming that the middle cantilever supports 50% of the load and each outer cantilever supports 25% of the load, determine the required dimension b. Round to the nearest whole number. b = mm (b) Assuming that the middle cantilever supports 50% of the load and each outer cantilever supports 25% of the load, determine the required dimension h. Round to the nearest whole number. h = mm
