You have three 24 ft long wooden 2-6's and you want to nail them together in two possible arrangements as shown below to make the stiffest possible beam. The stiffness of a beam is proportional to the moment of inertia of the beam's cross-section about a horizontal axis passing through its centroid The actual dimensions of nominal 2-6 lumber are 1.5 in t by 5.5 in Arrangement A: Arrangement B: Which of the following option is correct? O Arrangement A has approximately 3.62 times the stiffness of arrangement B O Both arrangements A & B are equally stiff. O Arrangement B has approximately 3.62 times the stiffness of arrangement A O Arrangement A has approximately 7.24 times the stiffness of arrangement B
