Question
A small balcony constructed of wood is
supported by three identical cantilever beams (see
figure). Each beam has length L1 = 2.1m, width b,
and height h = 4b/3. The dimensions of the balcony
floor are L1 XL2, where L2 = 2.5 m. The design
load is 5.5 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
Υ = 5.5 kN/m3.) The allowable bending stress in the
cantilevers is 15 MPa.
Assuming that the middle cantilever supports
50% of the load and each outer cantilever supports
25% of the load, determine the required dimensions b
and h.
