A short post, 150 mm by 150 mm, of Douglas fir, is reinforced by the addition of two ASTM A36 steel plates. The cross section is shown. Assume the x components are of equal lengths and are connected so that they act as a single unit and deform equally. Use the nominal dimensions of the wood, as shown and compute the allowable compressive load. Allowable compressive stress for the steel is 146 MPa and allowable compressive stress for the wood 7.24 MPa. Note: the modulus of elasticity for steel is 207,000 MPa and the modulus of elasticity of Douglas fir is 12,000 MPa. Steel plate 150 mm x 10 mm (typ.) Timber post 150 mm X 150 mm

A 5 ft. long laminated wood beam is built up by gluing together three 2” x 6” boards to form asolid beam 6” x 6” cross section, as shown in the figure. Calculate the maximum allowable valueof P (lb.) such that both the (1) allowable shear stress in the glued joints of 100 psi and the (2)allowable bending stress of 1200 psi is not exceeded. (Disregard the weight of the beam).[Formula: Bending Stress:  = (M)(y)/I; max = (M)(c)/I; Transverse Shear Stress:  =(V)(Q)/(I*t); max = (V)(QNA)/(I*tNA)]

A steel bar is attached to a wood support beam with four 21 mm diameter lag screws, as shown in the figure. The steel bar is 66-mm-wide by 9-mm-thick. The yield strength of the steel is 265 MPa and the ultimate bearing strength is 345 MPa. For the lag screws, the ultimate shear strength is 160 MPa. If a factor of safety of 1.85 with respect to yield strength, 3.5 with respect to bearing strength, and 2.8 with respect to shear strength is required, determine the allowable load P that can be supported by this connection. For the yield strength criterion, consider the constant cross-section part of the steel bar.
