of values in a set of data, along with an enumeration of the number of time each value or range of values is actually observed in that set. In a relative frequency distribution, the actual frequency of observations is replaced by the corresponding proportion of the total number of ...
题目The frequency of oscillation of an object suspended on a spring depends on the stiffness k of the spring (called the spring constant) and the mass m of the object. If the spring is compressed a distance a and then allowed to oscillate, its displacement is given by f(t)=acos √ ()...

A spring with a constant k 8 n m is stretched 5 cm and released. It Bobs up and down every 2.5 sec. What is its frequency, period and amplitude? What is the frequency of oscillation of the wave in the figure? If the sound becomes louder, which wave characteristics are likely increasin...
(1.11) becomes the frequency response function of the SDOF spring-mass-dashpot system. The frequency response function amplitude versus frequency of the SDOF can be obtained from executing the programming codes as shown in Figs. 1.2–1.4 where a sine wave signal of fixed excitation amplitude is ...

Under a Creative Commons license open accessHighlights Abstract Although there are literatures to characterize the properties of anisotropic magneto-rheological elastomer (MRE), more attention is paid when the particle chain is parallel to the applied magnetic field. However, in prospective of modeling ...
