In this blog post I will be talking about the I beam that I built. The beam took me about 30 minutes to build but it was definitely worth it because I tested it had it had a lot of capacity. Also I did not expect it to be so strong but it was and it carried about 6 heavy books. My other beam that I built was nowhere near as strong as the I beam but it was still pretty strong. On my I beam I had rubber bands to keeps the bends to make it stronger.
