What are Dynamometers?
Dynamometers are specialized instruments used to measure an engine’s revolutions per minute (RPM) and torque. RPM is a measurement of the number of times the crankshaft revolves inside an engine. The more revolutions a crankshaft makes each minute, the faster and more powerful the engine is. There are many parts inside a car’s engine, including the crankshaft and pistons. The crankshaft is similar to a bicycle’s pedals, with the bicyclist’s legs being the pistons. The pistons push the crankshaft and cause it to rotate. As a result, the crankshaft causes the drive shaft, which is like the bicycle’s chain, to move. This causes the axle and tires to rotate, making the car move. RPM must be within a specific range in order for a person’s automobile to run smoothly and efficiently. Incorrect engine measurements can be a sign of engine troubles. Dynamometers allow the car owner or mechanic to test the RPM to ensure it is where it needs to be. Charles Babbage, often referred to as the “Father
