OK . . .What does a 5W-30 do that an SAE 30 won't? When you see a W on a viscosity rating it means that this oil viscosity has been tested at a Colder temperature. The numbers without the W are all tested at 210Â° F or 100Â° C which is considered an approximation of engine operating temperature.
(Answer #1). The Industrial Revolution was a time when the world's economy started to be more industrialized -- things came to be made in factories rather than by individual artisans. Great Britain took the lead in this largely because of geography.y about mid nineteenth century it took firm roots in western Europe and northeastern USA. The industrial revolution first developed in Great Britain for several reasons. The two most important of these are abundant supply of coal and iron and the economic advantages accruing to the country because of its colony.
Britain led the way in this transformation. By the 1780s, the British Industrial Revolution, which had been developing for several decades, began to further accelerate. Manufacturing, business, and the number of wage laborers skyrocketed, starting a trend that would continue into the first half of the 19th century.mong the Western European countries, Britain was the ideal incubator for the Industrial Revolution because an Agricultural Revolution preceded it. After the 1688 Glorious Revolution, the British kings lost power and the aristocratic landholders gained power.
