As a mechanical engineer I tend to focus mostly on the mechanisms that actually do the work. Sometimes it’s easy to forget about the components that take the work. I’m talking about bearings. They’re so essential¬†for many things with moving systems, from everything to your car to a simple valve. The purpose of a bearing is to allow relative motion with a minimum amount of friction. On that end, the material for the bearing can become an incredibly crucial point. For high stress applications it needs to have good tensile and fatigue strength. But in order to absorb energy and not damage surrounding components you also might want it to be soft and with a low melting point. If you’re dealing in the aerospace industry you can bring in a third complication: weight. Bearings can be anything from a simple roller ball style to a flat plate bearing. Plates can…
