“How can we use force and rotation to deal with complex situations?”
One of the principal ideas in engineering is transferring force and rotation to perform useful activities. However, simple machines are often not enough to deal with the complex and varied nature of high-level problems. So how can we use our engineering mindsets to solve this? Well, what if we were to make our machines to be assembled of a complex assemblage of parts such as gears, belts, linkages, and chain drives? This framework is known as a mechanism and is the basis for many modern day machines such as drivetrains, internal combustion engines, and aircraft landing gears.
