Abstract In laboratory 5, “Boom Construction Competition”, the concepts of material failure, stress and strain were introduced, as well as booms and the work that they do. The students had been asked to construct a boom. The booms were tested, and competed within the lab. The ideal design was a boom that had a long arm, at least 1.5 meters, and was able to carry objects as heavy as possible. Introduction The main principle of a boom …

…not to bend. In order to strengthen the base, the two supporters should be cut into as long as the diameter of the anchor. Second, the boom should be made so it connected to the anchor well and fully, in order to be more strong and steady. Lastly, the arm of the boom should be strengthened and longer, so that it could be able to carry more weight and get higher weight ratio. ------------------------------------------------------------------------ **Bibliography**
