A simply supponted beam as shown in FigI is made from sevenal wooder pieces os shown in Fig-2. Specify the spacing of the
10mmlog
serews that are necessary to fasten this together. Assume that one
10mmlog
screw is good for
2kN
when transmitting lateral load parallel to the grain of the wood. Fon the entire section,
I=2.36*10^(9)mm^(4)
500mm
