An energy transfer refers to the process of energy being transmitted or passed from one system or component to another. In a chain reaction machine, energy transfers are crucial for the continuous and sequential activation of different components, ultimately leading to the desired outcome. These […]
Be sure to review the EMDC Handbook for specific rules related to mechanical components. A mechanical component or a “simple machine” is one that converts or transfers energy from one source to another physically. It is the simplest form of using one thing to accomplish […]
The six simple machines are fundamental mechanical devices that provide a foundation for understanding more complex machines. They are often referred to as the building blocks of machines and can be used individually or in combination to perform various tasks. Simple machines can be combined […]
