Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Ball bearing Wikipedia

Mar 18, 2003These bearings are assembled by placing the inner ring into an eccentric position relative to the outer ring, with the two rings in contact at one point, resulting in a large gap opposite the point of contact. The balls are inserted through the gap and then evenly distributed around the bearing assembly, causing the rings to become concentric.

Drag of a Sphere NASA

May 05, 2015The aerodynamic drag on an object depends on several factors, including the shape, size, inclination, and flow conditions. All of these factors are related to the value of the drag through the drag equation. D = Cd * .5 * rho * V^2 * A Where D is equal to the drag, rho is the air density, V is the velocity, A is a reference area, and Cd is the drag coefficient.

How can I find the mass of a steel ball given its radius

Jun 27, 2008The radius of the steel ball is r = 2cm = 0.02m and its specific heat is c = 0.486kJ/kgK Analyzing the units of these given values, I thought simple unit analysis would work. For example, 1/c would give units of kgK/kJ. The volume of the ball is v = (4/3)pi(r)^3 which has units of m^3. I'm having a difficult time trying to relate these things and manipulate them to just get the mass of this ball.
