Complex Stuff Explained in Simple Animations

how stuff works 111x100 Complex Stuff Explained in Simple AnimationsMechanisms are used to convert between one type of motion and another. Any machine can be looked on as a group of interconnected mechanisms which convert one type of motion to a variety of other motions.

These changes may be to convert rotary motion to straight line motion or to convert reciprocal (back and forth) motion to intermittent motion. They may also transform a fixed type of motion, for example by magnifying a linear motion or by slowing down a rotary motion.

Today we have tried to explain complex mechanisms in simple 3D animations

Bobbin works 550x359 Complex Stuff Explained in Simple Animations

I have always wondered how a bobbin works when I was young. And when I’m getting older, this bobbin has gone totally out of my mind. But after I have stumbled upon these animations and videos, this thing has shred some light on.

Just look at the graphic, that is really amazing. Whoever invented it at that time is really genius. This machine work with the perfect timing. The connection is really perfect

No 9. How Steam Engine Works

steam engine Complex Stuff Explained in Simple Animations

The most important part of a steam engine is the steam boilers, or what they are more commonly called, the steam generators. The motor unit of a steam engine is referred to as the ‘steam engine’. The basic requirement for the steam engine is the boiling of the water and the boiling process is attained by burning combustible materials. For example, the basic combustible materials, like coal, was used in many old steam engines. Nowadays, even nuclear energy and geothermal energy sources are utilized for the boiling of water. The enclosed chamber, where the boiling process occurs, is supplied with air so as to support the combustion of the fuel that is being used. The chamber is called as the combustion chamber or firebox. More precisely, the the term boiler or steam generators is used to refer the pressure vessels, that are used to boil the water. The term boilers, was more frequently used in the earlier times, but today it is more popularly known as the steam generators. Generally, there are two type of boilers, the fire-tube boilers and water-tube boilers.

The motor unit is hailed as the driver of the steam engine, as it is the place where the heat is converted into mechanical work. The motor unit receives the influx of steam at a very high temperatures and pressure and also allows the steam to exit at a low temperature and pressure, thereby creating a pressure difference. This energy is utilized in the mechanical work of the steam engine wheels, as it is the place where the heat is converted into mechanical work. A startling fact about water is, that when it is converted into steam, water expands to about 1600 times than its usual volume. The enormous force produced by this conversion process forms the backbone of the steam engine power. How does a steam engine work? Well, the water from the firebox is transferred to the pressurized boiler, where the water boils and is converted into steam. The steam is then passed through the motor unit, which contains a piston inside a cylinder, that is used to push the steam to the working machinery. The powered machinery drives the steam engine and this is how the heat energy of the steam is converted into mechanical work. Crankshafts are also attached to the power machinery, to convert the linear motion of the pistons into rotatory motion. Steam engine once used in locomotives was based on the reciprocating principle as shown below

It is indeed surprising to know how do steam engines work and especially how they convert one form of the energy into other. The basic principle of conversion of heat energy into mechanical work has been craftily employed in the working of steam engines.

No 8. How Radial Engines Works

radial engine works Complex Stuff Explained in Simple Animations

The radial engine idea is very simple — it takes the pistons and arranges them in a circle around the crankshaft, as shown here:

You can see in the illustration that this is a five-cylinder engine — radial engines typically have anywhere from three to nine cylinders. The radial engine has the same sort of pistons, valves and spark plugs that any four-stroke engine has. The big difference is in the crankshaft.

Instead of the long shaft that’s used in a multi-cylinder car engine, there is a single hub — all of the piston’s connecting rods connect to this hub. One rod is fixed, and it is generally known as the master rod. The others are called articulating rods. They mount on pins that allow them to rotate as the crankshaft and the pistons move.

Below if the video showing How a Radial Engine Works, Radial Engine’s are mostly used for Airplanes. Radial engine in video below is based on the Pratt & Whitney Twin Wasp

The Geneva drive or Maltese cross is a mechanism that translates a continuous rotation into an intermittent rotary motion. It is an intermittent gear where the drive wheel has a pin that reaches into a slot of the driven wheel and thereby advances it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps.
