Heavy equipment are heavy-duty vehicles. They are specially designed for completing construction tasks involving digging. Other known names for heavy equipment are heavy machines, heavy trucks, construction equipment, engineering equipment, heavy vehicles, or heavy hydraulics. They are typically operated by skilled workers that have gone through specialized training. While many categories of equipment utilizes continuous tracks for rough conditions, others favor tires when possible for their greater mobility. The tires selected play a significant role on the production of the project and the cost of the heavy equipment. These three types of tires include, transport for earthmoving machines, work for slow moving earthmoving machines, and load and carry for transporting as well as digging. Heavy equipment applies leverage, like other simple machines (levers, pulleys, etc.), to multiply the effectiveness of the energy put in. The majority of these machines use diesel power to complete tasks.
External combustion engine
An external combustion engine (EC engine) is an engine which converts heated fluid into kinetic energy. The heated fluid, called working fluid, can be air, hot water, pressurized water or liquid sodium which is heated in a boiler. The fluid used to power the engine is cooled and reused in a closed cycle and the fluid is dumped in an open cycle.
Any combustion engine follows the basic idea of converting fossil fuels into motion. Internal combustion engines do this by converting the energy created by an explosion of the fossil fuels, into motion. External combustion engines, on the other hand, use the energy from burning fossil fuels to expand a gas or liquid and use the expansion to create motion. The addition of this intermediate step is what differentiates an internal vs. external combustion engine. External combustion engines came first, and tend to be more inefficient. Famous examples of external combustion engines are steam engines
There are two types of external combustion: single phase and dual phase. In a single phase engine, the fossil fuels are burned to heat up a gas, which then expands and creates motion. In this case, there is no phase change.
With dual phase, you need one additional mechanism known as a phase transition. This process transforms the phase of liquid to gas. This converts temperature to usable work. Some common examples that use dual-phase engines are steam engines and engines that use Organic Rankine Cycle.Novelty song
A novelty song is a type of song that is meant to be funny, usually because of silly lyrics or lyrics that don't make a lot of sense. A song is considered a novelty song when it uses strange lyrics, strange music, out-of-the-ordinary subject matter, or any combination of the above. However, not all comedic songs are novelty songs.
Novelty songs are often parodies, mocking or poking fun at a popular topic or fad.
