What is stress relaxation in polymers? In materials science, stress relaxation is the observed decrease in stress in response to strain generated in the structure. Stress relaxation describes how polymers relieve stress under constant strain. Because they are viscoelastic, polymers behave in a nonlinear, non-Hookean fashion. What is relaxation time in polymers? Viscoelastic models of […]
What is diametral pitch in spur gear?
What is diametral pitch in spur gear? The Diametral Pitch (DP) is the number of teeth per inch of diameter of the pitch circle. The units of DP are inverse inches (1/in). The Diametral Pitch (DP) is equal to π divided by the Circular Pitch (CP). How do you calculate diametral pitch? Diametral Pitch is […]
How did interchangeable parts improve manufacturing?
How did interchangeable parts improve manufacturing? Interchangeable parts, popularized in America when Eli Whitney used them to assemble muskets in the first years of the 19th century, allowed relatively unskilled workers to produce large numbers of weapons quickly and at lower cost, and made repair and replacement of parts infinitely easier. Where were interchangeable parts […]

What is the physical significance of Fourier number?
What is the physical significance of Fourier number? The Fourier Number (Fo) is a dimensionless group which arises naturally from the nondimensionalization of the conduction equation. It is very widely used in the description and prediction of the temperature response of materials undergoing transient conductive heating or cooling. What is the physical interpretation of the […]
What is a peer reviewed journal articles?
What is a peer reviewed journal articles? Peer-reviewed (refereed or scholarly) journals – Articles are written by experts and are reviewed by several other experts in the field before the article is published in the journal in order to ensure the article’s quality. (The article is more likely to be scientifically valid, reach reasonable conclusions, […]
What is Solar Pond?
What is Solar Pond? A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a “halocline”, in which low-salinity water floats on top of high-salinity water. What is Solar Pond explain with diagram? A solar pond is a solar […]
