51 INTRODUCTIONIn one extreme, the vibration environment may consist oflow-level seismic disturbances present everywhere on earth,which present operating problems to highly sensitive itemssuch as delicate optical equipment. When other disturbancesare superimposed on the seismic disturbances, a wide range of precision equipment is adversely other disturbances are caused by such things as vehicular and foot traffic, passing trains, air conditioning systems, and nearby rotating and reciprocating cause resolution problems in electron microscopes, disturb other optical systems, cause surface finish problemson precision grinders and jig borers, and hamper delicatework on concept is the detrimental effect of vibrating internal components of certain equipment such as motors,blowers.
53 Natural Frequency: Natural frequency may be defined as the number of oscillations that a system will carry out in unit time if displaced from it equilibrium position and allowed to vibrate freely.
