Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the behavior of . A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the . The temperature of the sample or the frequency of the stress are often varied, leading to variations in the complex modulus; this approach can be used to locate the temp. The dynamic mechanical analysis method determines elastic modulus (or storage modulus, G'), viscous modulus (or loss modulus, G″), and damping coefficient (tan Δ) as a function of temperature, frequency or time. Results are usually in the form of a graphical plot of G', G”, and tan Δ as a function of temperature or strain. [pdf]

One application of an RCcircuit is the relaxation oscillator, as shown below. The relaxation oscillator consists of a voltage source, a resistor, a capacitor, and a neon lamp. The neon lamp acts like an open circuit (infinite resistance) until the potential difference across the neon lamp reaches a specific voltage. At that. .
The time period can be found from considering the equation VC(t)=ϵ(1−e−t/τ),VC(t)=ϵ(1−e−t/τ), whereτ=(R+r)C.τ=(R+r)C. .
One application of the relaxation oscillator is for controlling indicator lights that flash at a frequency determined by the values for R and C. In this. [pdf]
