A force is a push or a pull upon an object that may cause the object to change velocity. Forces are vectors, meaning that they have both magnitude and direction. If a person pushes a box with a force of 10 N towards the right, the magnitude is 10 N and the codirection is to the...

The cutting speed Vc is the relative velocity of the workpiece and tool at the tool edge. For any point on the tool edge it can be considered as a vector, and the cutting force Fc is measured along the line of this vector. The elementary relationships should be noted: 1. Energy/min ...
where uz [m s−1] is the velocity in the axial direction, ci [mol m−3] is the bulk concentration of species i, Ji [mol m−2 s−1] is the flux of species i through the membrane, Pm [m] is the circumference of the membrane, Ar [m2] is the cross-sectional area of the...
