APPARATUS FOR DETERMINING THE NUMBER OF VIBRATIONS PER SECOND OF A TUNING-FORK.LOUIE E. KNOTT
The crucial experiment was almost aborted before it could begin because Sommerfeld forbade his assistants, Friedrich and Knipping, to get involved with von Laue; Sommerfeld's reason was that he estimated that thermal vibrations in crystals would be so large at room temperature that the essential ...
If the velocity of the gas/fluid equals or exceeds the speed of sound, shock waves are set up, and vibrations and other mechanically related problems may result, compared to the conditions when velocities are below the speed of sound [72]. For a Mach of 1.0, the gas velocity equals the...
the contraction of vibrations. In pure perception we are actually place outside ourselves, we touch the reality of object in an immediate intution.199) Volume 28 of Modern Language Notes (No. 1-8, Jan.-Dec. 1913), pp. 1-264 Johns Hopkins Press, Baltimore, Maryland Managing Editor: C....
The amplitude,A,of the oscillation is the maximum displacement,either linear or angular,of the body from its equilibrium position. 震动的振幅,A,是距其平衡位置(震动的)最大位移,不管是直线运动还是摆动。 Mechanical vibrations which are maintained by elastic,and sometimes gravity,forces are called free...
It's all around us, no matter what we do, or where we go. Sound. The vibrations of the molecules that generate the effects on our ears we call sound. But what if sound goes deeper than that? What about the aspect of sound that goes beyond what we can hear? As the ancient Buddhist...
In the second approach, termed active structural acoustic cloaking, control forces are applied to directly excite the elastic shell. The structural response is actively modified to manipulate the scattered and radiated acoustic fields arising from plane wave excitation of the shell. The effectiveness of...
The temperatures, vibrations, shocks, accelerations, pressures, and other conditions imposed on a system due to the operation or handling of the system. induced failure A failure that is basically caused by a condition or phenomenon external to the item that fails. induced voltage The voltage prod...
