= = 8. A solid-sawn 6 x 6 (actual size: 5.5 in x 5.5 in.) truss member bears on another 6 x 6 member at an angle of 60°. Both pieces of lumber are select structural Douglas Fir. The compression strengths of the lumber parallel and perpendicular to the grain, respectively, are F || = 1600 psi and F1 = 505 psi. What is the compression strength of the lumber with load acting at 60°. A. 495.4 psi B. 637.8 psi C. 1198.8 psi D. 405 psi E. None of the above (i.e. none of A, B, C, and D)
