CHAPTER 1 Graphs are used to study the relationship between 2 things so you can see what the relationship is. Unrelated: 2 items that are not associated. Ex. Hair color is unrelated to shoe size Directly related/proportional: 2 items that are associated such that when one item increases‚ the other increases. The graph of 2 directly related items extends from lower left to upper right. Ex. Clothing size is directly related to one’s weight. Related/ proportional: Is a relationship but can’t

Beginning Vibration Analysis with Basic Fundamentals By: Jack Peters Beginning Vibration Introduction Understanding the basics and fundamentals of vibration analysis are very important in forming a solid background to analyze problems on rotating machinery. Switching between time and frequency is a common tool used for analysis. Because the frequency spectrum is derived from the data in the time domain‚ the relationship between time and frequency is very important. Units of acceleration‚ velocity

Wavelength (l) and Frequency (n) Relationships c=ln ‚ where l is wavelength in meters n is frequency in hertz‚ 1/s or s-1 c=3.0 x 108m/s (the speed of light in a vacuum) Typical question #1- What is the frequency of red light with a wavelength of 690.nm? (1m=109nm) First- l is wavelength in meters‚ so convert nm to meters 690.nm ( 1m )=6.90 x 10-7m 109nm Now we can rearrange the equation above and solve for frequency‚ since

CIRCUITS LABORATORY EXPERIMENT 3 AC Circuit Analysis 3.1 Introduction The steady-state behavior of circuits energized by sinusoidal sources is an important area of study for several reasons. First‚ the generation‚ transmission‚ distribution‚ and consumption of electric energy occur under essentially sinusoidal steady-state conditions. Second‚ an understanding of sinusoidal behavior makes possible the prediction of circuit behavior when nonsinusoidal sources are used through the use of techniques
