Methods of Reducing Friction
Friction can be reduced by the following methods:
- The various parts of the machines that are moving over one another are properly lubricated.
- In machines, the sliding of various parts is usually replaced by rolling. This is done by using ball bearings.
- Where sliding is unavoidable, a thick layer of greasing material is used between the sliding surfaces.
- The front of the fast moving objects, e.g. car’s, airplanes are made oblong to decrease air friction.
Visual cues immediately grab our attention and improve memory. In an audiobook, this is impossible. However, with practice, your listening skills will improve. The same is true for screen reading. Over time, you will become better at memorizing information from an e-book. Let’s summarize. If you need a book for study or work, read on paper.
