In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh. If you take a flywheel with a heavy metal rim and replace it with a rim that's twice as heavy (double its moment of inertia), it will store twice as much energy when it spins at the same speed. But if you take the original flywheel and spin it twice as fast (double its angular velocity), you'll quadruple how much energy it stores. [pdf]

When the experiment is run at higher frequencies, the storage modulus is higher. The material appears to be stiffer. In contrast, the loss modulus is lower at those high frequencies; the material behaves much less like a viscous liquid. In particular, the sharp drop in loss modulus is related to the relaxation time of the material. [pdf]

[FAQS about The storage modulus suddenly increases]
At lower frequency, the storage modulus is lesser than the loss modulus; it means viscous property of the media dominates the elastic property. As the frequency increases, the storage modulus increases; it shows the abrasive media has the capacity to store more energy, and it crosses loss modulus at a point called cross-over point. [pdf]

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]

The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage (SHS) is the most straightforward method.
