steam engine

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Water turns to steam in a boiler and reaches a high pressure. When expanded through pistons or turbines, mechanical work is done.The idea of using boiling water to produce mechanical motion has a very long history, going back about 2,000 years. Early devices were not practical power producers, but more advanced designs producing usable power have become a major source of mechanical power over the last 300 years, beginning with applications for removing water from mines using vacuum engines.

this is a diagram of how the steam engine works.

the idea of a steam engine started with the water wheel.The first steam engine was created by James Watt (1736-1819) James Watt was a Scottish inventor and mechanical engineer, born in Greenock, who was renowned for his improvements of the steam engine. In 1765, James Watt while working for the University of Glasgow was assigned the task of repairing a Newcomen engine, which was deemed inefficient but the best steam engine of its time. That started the inventor to work on several improvements to Newcomen's design.

cotter spinning machine

Spinning is a major industry. It is part of the textile manufacturing process where three types of fibre are converted into yarn, then fabric, then textiles. The textiles are then fabricated into clothesor other artifacts. There are three industrial processes available to spin yarn, and a handicraft community who use hand spinning techniques. Spinning is the twisting together of drawn out strands of fibers to form yarn, though it is colloquially used to describe the process of drawing out, inserting the twist, and winding onto bobbins.

The spinning machine takes the roving, thins it and twists it, creating yarn which it winds onto a bobbin.

In mule spinning the roving is pulled off a bobbin and fed through rollers, which are feeding at several different speeds.This thins the roving at a consistent rate. If the roving was not a consistent size, then this step could cause a break in the yarn, or could jam the machine. The yarn is twisted through the spinning of the bobbin as the carriage moves out, and is rolled onto a cop as the carriage returns. Mule spinning produces a finer thread than the less skilled ring spinning.

• The mule was an intermittent process, as the frame advanced and returned a distance of 5ft.It was the descendant of a 1779 Crompton device. It produces a softer, less twisted thread that was favoured for fines and for weft.
• The ring was a descendant of the Arkwright water frame of 1769. It was a continuous process, the yarn was coarser, had a greater twist and was stronger so was suited to be warp. Ring spinning is slow due to the distance the thread must pass around the ring, and similar methods have improved on this; such as flyer and bobbin and cap spinning.

Sewing thread, was made of several threads twisted together, or doubled.

the process of spinning cotton was the first of the one man one job idea . this changed the way of producing products even now to day this process is still being used in factories and outlet stores.

farming

Between the medial time period and 1800 the farming system was a basic but an effective system this was called the 'open field system'. At the end of 1800 there was another type being introduced this was called the 'enclosed field system'.This lead to more food production and this meant the farmers could gather more and more food to sell.

this is an example of an open field system.

this is an example of an enclosed field system.

 Increasingly, people enclosed and managed their woodlands by copping to obtain sustainable supplies of fuel for charcoal for gunpowder and iron making, and for tanbark and oak to split for basket weaving. New techniques also led to increased energy efficiency, e.g.charcoal production, of which fast quantities of charcoal was needed. Around industrial cities such as Sheffield in England, woodlands were carefully managed to sustain the cities steel production. This was soo efficient that the inferior fule of coal did not replace charcoal until the 1820s. The response to the wood shortage was the shift to a new fuel: coal. Britain had enough of it and there were many seams at the surface, easy to exploit, especially in the Tyneside area around Newcastle. Despite the obvious dependency on wood, Europeans cleared forests to create arable land to feed a growing population, placing pressure on the forests.

the sewer system

The sewer system was underdeveloped for growth of the major industrial cities that caused water pollution.  All too often, rivers that pass through urban areas became a receptacle for human waste products, both domestic and industrial. Sewage, as in most cities, was washed out into the streets where it found its way to the rivers with disastrous consequences.the consequences for having an undeveloped sewer system was that when it rained the sewers would back up and flood peoples homes in the mixture of sewer and water. As time went by the mixture leaned further and further towards pure sewer until the rain water had no where else to go. This lead to the rivers filling and overflowing into the cities where the water born disease choler was killing more and more people every day.

London’s example of building adequate sewer systems and treatment plants was soon followed by other cities making urban environments much cleaner. However, much sewage was still discharged in open water outside cities and air pollution continued unchecked until the mid-20th  century.
