Engineering in brief
Define the term engineering in brief.
Expert
The application of science to the requirements of humanity and a profession in which the knowledge of mathematical and natural sciences gained through study, experience and practice is applied with decision to develop manners to utilize economically the materials and the forces of nature for the advantage of mankind.
Centrifugal pseudo force: A pseudo force which takes place whenever one is moving in uniform circular motion. One feels a "force" directed outward from the center of the motion.
Laue pattern (M. von Laue): The pattern generated on a photographic film whenever high-frequency electromagnetic waves (like x-rays) are fired at the crystalline solid.
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
Kohlrausch's law (F. Kohlrausch): When a salt is dissolved in water, the conductivity of the solution is the addition of two values -- one depending on the positive ions and the other on negative ions.
Siemens: S (after E.W. von Siemens, 1816-1892): The derived SI unit of an electrical conductance equivalent to the conductance of an element which has a resistance of 1 O [ohm]; this has units of O-1.
Hubble constant: H0 (E.P. Hubble; 1925): The constant that determines the relationship among the distance to a galaxy and its velocity of recession due to the growth of the Universe. As the Universe is self-gravitating, it is not trut
Briefly explain the procedure to compute the tensile strength?
What is the reason that heat causes matter to expand? Briefly explain it.
Briefly explain the measure of the force of gravity on the object?
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
