2. An axial load P is supported by a short W8x40 column of cross-sectional area A=11.7 inand 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.

The allowable tensile stresses of wires AB and AC are 100 MPa and 150 MPa, respectively. The cross- sectional areas are 400 mm2 for wire AB and 200 mm for wire AC. a. Determine the allowable force in wire AB in Kilo Newton. (20 points) b. Which of the following gives the maximum value of W without exceeding the allowable tensile stresses in wires AB and AC in Kilo Newton. (30 points) A ? 30° 45° W
