Bearings are produced in a variety of materials in order to suit their required application and each material type has pros and cons. We need to look at why each material performs in the way it does and this means looking into the material science Firstly, the most common bearing material is steel and it is used for a wide range of applications due to its ability to deal with high static loads as well as radial loads. Steel bearings tend to be made from a SAE 52100 steel known as a high carbon steel with low alloy. The material...

One of the greatest engineering feats designed and sold in Britain of our time has got to be the Land Rover series and defender. Designer back in 1948 by Spencer Wilks who used a jacked up rover to move around his land and this was named the "Land Rover" the Land Rover was then super ceded by the series one in 1958 and at this point was still on a ladder frame chassis and aluminium body which is still similar today in the latest model the defender. In 1971 the series three was launched and this came with a Synchromesh gearbox...

How to measure a V belt V belts are wedge shaped and are used to drive pulleys which have a reciprocating V shaped grove. This is important to know because it is key in the measurement of your belt. The thickness of the top edge or widest part of the belt is an important measurement as it dictates how far down the V groove it will sit. The idea is that the belt is pulled into the groove of the V and almost gets wedges there creating a lot of pressure against the pulley in the V and preventing slippage....

It has been at the forefront of most documentary channels for some years now. Car manufacturers and public transport are having to work hard to comply with new rules and regulation to help promote the preservation of our atmosphere. It is widely understood that burning fossil fuels to power our country is perhaps not the most efficient and seemingly one of the most harmful.  This great article published by Born to Engineer  highlights some of the huge steps forward we are making as a country to help sustain our planet via the use of wind farming. Im sure there is an...

How do Fidget spinners actually work? let's take a look!   This can be explained by physics and looking into how bearings work to reduce friction. Ball bearings in this case are constructed of an inner and an outer ring. In between this inner and outer ring sits balls that look to limit the amount of friction between the two rings. A bearing like the one pictured here can be found in the centre of the fidget spinner. Once you combine the physics theory of continued angular momentum with a bearing the limits friction you should get a free spinning fidget spinner. The...
