A glue-laminated column of 3-m effective length is to be made from boards of 24 x 100-mm cross section. Knowing that for the grade of wood used, E= 11 GPa and the adjusted allowable stress for com-pression parallel to the grain is σC= 9 MPa, determine the number of boards that must be used to support the centric load shown when (a) P= 34 kN, (b) P= 17 kN
An axial load P is supported by a short W8x40 column of cross-sectional area A=11.7 in? and is
distributed to a concrete foundation by a square plate as shown. Knowing that the average normal stress
in the column must not exceed 30ksi and that the bearing stress on the concrete foundation must not
exceed 3.0 ksi, determine the side "a" of the plate that will provide the most economical and safe
design.
