4. A wooden beam is fabricated from one 2 × 10 and two 2 × 4 pieces of dimension lumber to form the I-beam cross section shown in Figure. The flanges of the beam are fastened to the web with nails that can safely transmit a force of 200 lb in direct 4 in. 2 in. Nails 2 in. shear. If the beam is simply supported and carries a 5,000-lb load at the center of a 10-ft span, determine: (a) the horizontal force transferred from each flange to the web in a 12-in. long segment of the beam. (b) the maximum spacing s (along the length of the beam) 10 in. required for the nails. (c) the maximum horizontal shear stress in the I-beam. 2 in.
