How torque, radial, axial load impact motor selection
Without support, the force applied during the press-fit is directly transmitted to the front ball bearing, whose inner raceway is usually bonded to the motor shaft to absorb the axial loads. Supporting the rear shaft allows for a higher force during press-fitting, as the flow of force is going through the motor shaft, not the bearings. …

End Milling: Definition, Process, Types, and Operations
How Does End Milling Differ From Traditional Milling? Traditional milling, often referred to as conventional milling, differs from end milling primarily in the direction of tool rotation and the cutting forces applied during the machining process. End mill tools rotate in the same direction as the feed motion, which is typically clockwise when viewed …

8.1 Linear Momentum, Force, and Impulse
Impulse is a useful concept because it quantifies the effect of a force. A very large force acting for a short time can have a great effect on the momentum of an object, such as the force of a racket hitting a tennis ball. A small force could cause the same change in momentum, but it would have to act for a much longer time.
