For the wear resistance of sliding contacts geometry, contact force and coating system are strong factors of influence. In this paper a mathematical description of the available wear volume of frequently used hemispherical and U-type geometries is given. Smooth surface layers are worn abrasively and...
Watts are SI (metric) units for power, and calculating power usually isn't difficult. There are two ways to do it, though, depending on whether you're talking about mechanical or electrical power. The watts equation for an electrical circuit takes into account the voltage across the circuit ...

Maxwell's Fourth Equation expresses the observation that a continuous electrical current I or a displacement current (∂D/∂t) gives rise to a magnetic field. At a distance r from a wire with direct current I, for example, the magnetic field is given by (4.20G)H=2Icr (4.20S)H=I2...
What is Coulomb's law? Learn the formula and calculations involved in finding the electrostatic force between charged particles, with some examples.
In other words, Maxwell's equation of electromotive force is identical to what has become known as the Lorentz force equation for a moving unit electric charge. Reflections on Maxwell's Treatise He begins with a review of Maxwell's equation and discussion of the operation of antennas and antenn...
Approximate analytical expressions are given for the field-driven flux, electrical power absorbed, free-energy produced per unit time, thermodynamic efficiency, and zero-flux concentrations. The field-driven flux is written as a generalized Michaelis-Menten equation. 展开 ...
(1) and (2) are two forms of the Bernoulli Equation for a steady state in-compressible flow. If we assume that the gravitational body force is negligible - the elevation is small - then the Bernoulli equation can be modified top = p1 + ρ v12 / 2 = p2+ρ v22 / 2 - ploss ...
The equation for Coulomb's law is shown below where the electric force of attraction or repulsion, {eq}F_q {/eq}, is equal to the product of the... Learn more about this topic: Coulomb's Law | Overview, Formula & Equation from ...
In this case, the force/area is of constant magnitude for all directions and the stress is said to be hydrostatic. The effect of stress or strain on the optical properties of a crystal is usually referred to as the photoelastic (or elasto-optic) effect. To quantify this effect we note ...
