Wrought iron is got by removing the carbon from cast iron.

Wrought iron is very pure, with a ferrite content of 99.95%. The remaining 0.05% is slag, picked up during the smelting process.

Wrought iron is easily bent or twisted when cold, but it has excellent resistance to fracture when subjected to sudden shocks or blows.

A Zener diode behaves like an ordinary diode up to a certain point. In other words, it acts as a one way electrical valve that allows electricity to flow in one direction only. It does this up to a certain point. However, when voltage acting against the normal flow rises to a certain point, the Zener collapses and conducts freely in both directions. It will continue to do that until the voltage acting against the Zener drops below a given value. Once this happens, the Zener again behaves like an ordinary diode.

Zener diode symbol.

Because of this quality, the Zener is especially useful in voltage regulation circuits.

Non-ferrous metal with excellent resistance to corrosion. Often used to cover and protect mild steel-for example in corrugated roof sheets.

Letter from the Greek alphabet used on the CP course to represent the coefficient of friction when carrying out calculations in the Transmissions Module of the course.

The co-efficient of friction between two surfaces is simply the relationship or ratio between those two forces. If I want to move a body along a surface at a constant speed, it will require a certain force. The magnitude (size) of that force depends upon the nature of the two surfaces in contact and the downward force pushing the two surfaces together.

The Sterling Engine is a simple piece of engineering that runs on hot and cold air.

The engine has very few parts:

When the bottom of the Cylinder is heated the air will rise pushing the Piston to the top of the Cylinder. When the Piston reaches top dead center the Diaphragm pulls all the hot air in, the Piston drops back down to Bottom Dead Center and the Diaphragm pushes the hot air back into the Cylinder. This process is constantly repeated.
