Brush physics
A brush or carbon brush is an electrical contact which conducts current between stationary wires and moving parts, most commonly in a rotating shaft. Typical applications include electric motors, alternators and electric generators. The lifespan of a carbon brush depends on how much the motor is used, and how much power is put through the motor. http://hades.mech.northwestern.edu/index.php/Brushed_DC_Motor_Theory

Brush was born in Bangor, Maine, USA and he studied Physics and Chemistry at Harvard University, earning a Bachelor of Science in Physics at the age of 20 in 1955. He was selected as a Rhodes Scholar and he earned his Doctor of Philosophy (D. Phil.) in theoretical physics from the University of Oxford in England in 1958. He was a National Science Foundation Postdoctoral Fellow at Imperial College London from 1958-1959.
WebThe effect of polydispersity in chain molecular weight may be accounted for in the theory; the experimental estimate of M W /M N = 1.02 makes a significant difference, as the polydisperse brush is predicted to be taller than the monodisperse brush by an amount of order (M W /M N - 1) 1/2.
WebJul 22, 1998 · We present results of Brownian dynamics simulations of polymer brushes under steady and oscillatory shear. The brush is sheared by a bare surface and the resulting solvent velocity and polymer dynamics are solved self-consistently.
