A few days ago in class we were talking about crankshafts. I didn’t get what a crankshaft was but soon later discovered more about it. The shaft is bent out so it can convert into circular motion. It sounds a bit confusing but to sum it up a crankshaft is essentially the backbone of an combustion engine. What the crankshaft is responsible for is the correct operation of the engine and that its converted into a circular rotational motion. A lot of the times you can find a crankshaft in a car. In cars you can most likely find them in the bottom end area of an engine. Crankshafts were a little confusing to understand but now I know that they are important mechanical devices.
