1. The problem statement, all variables and given/known data Why is a steel beam shaped in the form of the letter "I" still strong enough to bear a load? 1) Its compression area is located on the top of the I beam. 2) Its tension area is located on the top of the I beam. 3) Its neutral area is located on the top of the I beam. 4) Its compression area is in the middle of the I beam. 5) Its neutral area is located in the middle of the I beam. Most of the material in these I-beams is concentrated in the top and bottoms parts, called the flanges. The piece joining the bars, called the web, is thinner. Stress is predominantly int he top and bottom flanges when the beam is used horizontally in construction. One flange tends to be stretched while the other tends to be compressed. The web between the top and bottom flanges is a region of low stress that acts principally to hold the top and bottom flanges apart. 2. Relevant equations n/a 3. The attempt at a solution I think its #5, only because the neutral layer is in the middle of the block and that's where neither compression nor tension occurs. I figured that's why it can support a load. I'm unsure though and would like a second opinion.
