Torque (article) Khan Academy
Torque is a vector quantity The direction of the torque vector depends on the direction of the force on the axis Anyone who has ever opened a door has an intuitive understanding of torque When a person opens a door, The milling process definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap)This value is necessary for determining the true cutting data at the actual depth of cut (a p)This is a particularly important value Milling formulas and definitions TON Coromant

WOA1 Method for estimating the ball charge of a
In the present invention a method, apparatus and computer program are presented, with which the amount of balls among ore material contained in a grinding mill is estimated as a percentage by volume of the total volume of the mill Preferably, the invention relates to semiautogenous mills In the invention, an expanded Kalman filter is used to estimate θ = 180° (or π radians) This is a situation where the force vector points directly into r Again, shoving toward the axis of rotation isn't going to cause any rotation either and, once again, the mathematics supports this intuition Since sin (180°) = 0, the value of the torque is once again τ = 0 θ = 90° (or π /2 radians) HereCalculating Torque With Examples ThoughtCo
