Tensile strength is how resistant a material is to breaking down under tension, this is important in a vehicle body as the body will always be under tension in regular motion and would not be safe if it was to fail under small stresses.

Part 3: Practical Research Although I have tried my best to make my roller coaster model close to the real one, I have to admit that there are a number of features which could not be revealed in the model. In this part of the research, I will pay attention to some details of design of real roller coasters and further research on some roller coaster of new types. Composition Generally speaking, a complete roller coaster system contains several sub-systems, which include lifting system, braking…

One of the biggest moral conundrums in human history was the creation of the Atomic Bomb. The possibility of these weapons came into fruition soon after the discovery of nuclear fission and the potential energy that can be released. Once the thought of weaponizing this process was considered, many countries wanted to jump on its development and be the first to accomplish this feat, but like all next fields of discovery, had little understanding how to go about the process. Various trials and…
