A wooden beam is fabricated from one 2 x 10 and two 2 x 4 pieces of dimension lumber to form the I-beam cross section (b; = 4 in., tf = tw = 2 in., d, = 10 in.). The flanges of the beam are fastened to the web with nails that can safely transmit a force of 171 Ib in direct shear. If the beam is simply supported and carries a 980-lb load at the center of a 12-ft span, determine: (a) the horizontal force Fy transferred from each flange to the web in a 8-in.-long segment of the beam. (b) the maximum spacing s (along the length of the beam) required for the nails. (c) the maximum horizontal shear stress Tmax in the I-beam. bf ts dw Nails
