How a Pill Press Works



http://i.imgur.com/ezk59.gif

A tablet press is a mechanical device that compresses powder into tablets of uniform size and weight. A press can be used to manufacture tablets of a wide variety of materials, including pharmaceuticals, illicit drugs such as MDMA, cleaning products, and cosmetics. To form a tablet, the granulated material must be metered into a cavity formed by two punches and a die, and then the punches must be pressed together with great force to fuse the material together.

How Walschaerts Valve Gear in
Steam Locomotives Works


http://i.imgur.com/k9Oq5.gif


The Walschaerts valve gear is a type of valve gear invented by Belgian railway mechanical engineer Egide Walschaerts in 1844 used to regulate the flow of steam to the pistons in Steam Engines. The gear is sometimes named without the final “s”, since it was incorrectly patented under that name. It was extensively used in steam locomotives from the late 19th century until the end of the steam era.

What a Tesseract (4D Cube) Looks Like

http://i.imgur.com/mtzcN.gif


In geometry, the tesseract, also called an 8-cell or regular octachoron or cubic prism, is the four-dimensional analog of the cube; the tesseract is to the cube as the cube is to the square. Just as the surface of the cube consists of 6 square faces, the hypersurface of the tesseract consists of 8 cubical cells.

Knight’s Tour: How a Knight Visits
Every Square Once


http://i.imgur.com/PxsiD.gif
A knight’s tour is a sequence of moves of a knight on a chessboard such that the knight visits every square exactly once. The exact number of open tours on an 8×8 chessboard is still unknown.

Creating a program to find a knight’s tour is a common problem given to computer science students. Variations of the knight’s tour problem involve chessboards of different sizes than the usual 8 × 8, as well as irregular (non-rectangular) boards.

How a Constant Velocity Joint Works

http://i.imgur.com/zmBLa.gif
Constant-velocity joints (aka homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly used in front wheel drive and all wheel drive cars. Rear wheel drive cars with independent rear suspension typically use CV joints at the ends of the rear axle halfshafts, and increasingly use them on the propshafts.

How Circle Strafing Works

http://i.imgur.com/eLBdL.gif
In video games, strafing is the technique of moving the player’s character from side to side, rather than forward and backward. Circle strafing is the technique of moving around a target in a circle while facing it. Circle strafing allows a player to fire continuously at an opponent while dodging counterattacks. By rapidly circling the opponent, the player evades the opponent’s sights.
