A plain bearing used in industrial application operates at high speed under very high loads. All elements of this plain bearing (bearing and journal) are made of 080M40 steel. In order to prolong the life of the mattress, you are asked to replace one element of the plain bearing with the materials in the list below (journal or bearing will replace only one). Why which material would you choose?

  1. Rice
  2. Bullet
  3. Teflon

Note to question 1: To reach the answer to the question, you will draw conclusions from the results by using a number of formulas to reach the behavior of different materials in contact.

Ethanol (C2H5OH) is a very important chemical.in addition to being widely used as an industrial solvent,a gasoline additive,and an alternative fuel,it is well known as the alcoholic beverages.A common name for ethanol is grain alcohol because it is formed by the fermentation of glucose (C6H12O6) and other sugars in grains such as corn,wheat and barley: C6H12O6---'C2H5OH + CO2 The previous reaction has been carried out for many centuries and is one of the oldest manufacturing processes.In a more recent development,ethanol...

High-speed elevators function under two limitations: (1) the maximum magnitude of vertical acceleration that a typical human body can experience without discomfort is about 1.2 m/s2, and (2) the typical maximum speed attainable is about 9.1 m/s . You board an elevator on a skyscraper's ground floor and are transported 230 mabove the ground level in three steps: acceleration of magnitude 1.2 m/s2 from rest to 9.1 m/s , followed by constant upward velocity of 9.1 m/s , then deceleration...
