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.
The Industrial Revolution occurred between the late 1700s and the early 1900s. Originating in Britain, it was characterised by the introduction of machines for laborious work, the replacement of animal labour with human labour and the widespread use of mineral resources.he Second Industrial Revolution, which began in the 1860s in Europe, the US and Japan, saw great strides in the production of steel, railroads, electricity and chemicals, and was characterised by the mass-production and mass-consumption of goods.
