Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...

Using the weight equation above and solving for the free variables, the solution arrived at is = (/), where is the length and is the height of the beam. Assuming that b {\displaystyle b} , L {\displaystyle L} , and M {\displaystyle M} are fixed design variables, the performance index for bending becomes P C R = σ / ρ {\displaystyle P_{CR ...
