For the structure shown, design the maximum permissible value of W using a factor of safety of 2, based on the following conditions. a. Ultimate normal stress in members CD and EF is 140 ksi. b. Ultimate shear stress in pins B, D, F, and H is 100 ksi. c. Ultimate bearing stress on member ACEG is 200 ksi. d. Ultimate bearing stress on support plates at B and H is 240 ksi. All members have dimensions of 5 x 2 in while the support plates have 1.5 in. thickness. Pins at B and H have 1 in. diameter while pins C, E, D, and F have 3/4 in. diameter. Note that there are two identical members CD and two identical members EF. Also, there are two support plates in B while only one plate is used in H.
