Newton’s Cradle Animation showing the conservation of momentum and energy. Look at this largest cradle in development here.

A CV Joint

This is called a constant velocity joint. Look at how the rotation around one axis is transferred to a rotation around an axis which is at an angle to the first one. Here the importance of this CV joint is to reduce friction and constant velocity transfer like in a gear. These are applied in cars.

We use it in our bags, clothes so much that we ignore it!

Tesseract

A Tesseract is a three dimensional projection of a 4 dimensional cube. It “is to the cube as cube is to the square”. The above is the projection in 3-D when it actually rotates in 4-D!

Radial Engine

These engines are used in aircrafts. These are special in that they are flat and take smaller room. This helps the aircraft make turns easily and quickly. Hence it is also used in fighter aircrafts.

Juggling Balls

There is no need to explain these. Can you do this? Now you should be able to do given the above technical demo.

35 Sphere Pyramid

A pyramid made of 35 spheres is rotating. The spheres in different colors and being transparent make it look beautiful.

An AEG gun

It is an airsoft gun made by AEG. These guns are primarily created for recreational purposes. This shows internal working of its gearboxes.

Geneva Drive Mechanism

What did you notice? An intermittent motion. The first thing that came to my mind about its use is in clocks. Guess another application? It is also used in movie projectors where the film is not continuously shown one after another, but each one for 1/24th of a second. That results in a picture being shown at the same time animated due to our perception.

3-D Model of Human Face

Starting with eyes as two spheres, rest of the face is modeled with spider webs which finally shows the face.
