The manufacturers have spent huge sums of money to develop tribotesters. 5. Thousands of satellites have been launched by Russia and other nations into orbit around the Earth. 6. A number of wear tests have been developed by committees in an attempt to standardize wear testing for specific applications. 7. In a milling machine, a workpiece is fed by the feeding mechanism against a circular device with a series of cutting edges on its circumference. 8. These microscopies have greatly increased the ability of surface scientists to measure the physical structure of many surfaces.

VII. Сделайте грамматический разбор предложений:

1. When crushed ore is suspended either in water or an air blast, the heavier metallic mineral particles fall to the bottom of the processing chamber, and the lighter components are blown or washed away. 2. Unconventional machine tools employ light, electrical, chemical, and ultrasonic energy; superheated gases; and high-energy particle beams to shape the exotic materials and alloys that have been developed to meet the needs of modern technology.
