Is ductility the same as elongation? Ductility is the percent elongation reported in a tensile test is defined as the maximum elongation of the gage length divided by the original gage length. Reduction of area is the proportional reduction of the cross-sectional area of a tensile test piece at the plane of fracture measured after […]
What is the radius ratio rule?
What is the radius ratio rule? The ratio of radius of cation to anion is called radius ratio. In condensed matter physics and inorganic chemistry the cation-anion radius ratio (also: radius ratio rule) is the ratio of the ionic radius of the cation to the ionic radius of the anion in a cation-anion compound. What […]
How much energy is released in nuclear fission of u235?
Does a VIN number start with a number or letter?
Why does aluminum not have an endurance limit?
Why does aluminum not have an endurance limit? Aluminum does not have an endurance limit such as ferrous metals. Aluminum will fail if it goes though enough stress cycles. If the stress on the steel is above the endurance limit, the metal will fail and how quickly it fails depends on the magnitude of the […]
What is it called when Colours are next to each other on the Colour wheel?
What is it called when Colours are next to each other on the Colour wheel? An analogous color scheme is made up of colors next to each other on the wheel. For example, red, orange, and yellow are analogous colors. What are three colors next to each other on the color wheel? Analogous colours are […]
How does spatial disorientation affect a pilot?
How does spatial disorientation affect a pilot? Spatial disorientation can also affect instrument-rated pilots in certain conditions. A powerful tumbling sensation (vertigo) can result if the pilot moves his or her head too much during instrument flight. This is called the Coriolis illusion. What causes spatial disorientation? Spatial disorientation is more likely to occur when […]
How do you saturate a TLC chamber?
How do you saturate a TLC chamber? Chamber saturation method Fill the chamber with solvent to a height of 0.5 to 1 cm. Carefully tilt the chamber to moisten the filter paper and equilibrate the chamber with solvent vapors. After a few minutes, the chamber is saturated with vapors. Why do we saturate TLC chamber? […]
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 […]
What is stress relaxation in polymers?
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 […]
