Radio and Radar Frequency Bands
Military Radar Bands. Military radar band nomenclature, L, S, C, X, Ku, and K bands originated during World War II as a secret code so scientists and engineers could talk about frequencies without divulging them. After the war the codes were declassified and Ka band and millimeter (mm) were added. Military radar band nomenclature is widely used

Vibration Isolation Theory of Foundations
Operating frequencies of rotating/reciprocating machines often are very close to the natural frequency of their support structure (floor slab and soil). Compressors, for example, can generate vibration of substantial magnitudes at low frequencies that coincide with the natural frequency of the floor slab, thus creating a resonance

Inspection of work equipment - Work equipment and machinery
The purpose of an inspection is to identify whether work equipment can be operated, adjusted and maintained safely, with any deterioration detected and remedied before it results in a health and safety risk. Not all work equipment needs formal inspection to ensure safety and, in many cases, a quick visual check before use will be sufficient.
