w D L- พ L พ พ The cross-section of a wooden, built-up beam is shown below. The dimensions are L = 210 mm and w = (Figure 1) 25 mm. Determine the magnitude of the moment M that must be applied to the beam to create a compressive stress of σD = 34 MPa at point D. Also calculate the maximum stress developed in the beam. The moment M is applied in the vertical plane about the geometric center of the beam. Express your answers, separated by a comma, to three significant figures.

b=8 h = 10⁰ lx = 666 in ly=426 in 21'-0" 0.82 1. Given the allowable stress table for wood timbers provided with the list of formulas, consider the following for a 8" by 10" # 1 Hem-Fir column. b. If the column is detailed with intermediate bracing so that Lx = 28-0° and Ly=21¹-0", what is the maximum allowable axial load on the column? Answer: a. If the column is laterally braced about both the X and Y axes at the top and bottom, what is the maximum allowable length under an axial load (P) of 50,000#? Answer:
