Every element has a unique atomic number. This is the number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives ...
An alloy like this will form only if the atoms of the base metal and those of the alloying agent are of roughly similar size. In most substitution alloys, the constituent elements are quite near one another in the periodic table. Brass, for example, is a substitution alloy based on copper...
For example, damaged or worn gears will indicate frequencies of dominant vibration related to the RPM speed times the number of gear teeth. Some common vibration problems in machines and uses for spectrum analysis are listed below: Gearbox failures Bearing element failures Mechanical looseness Imbalance...
