Ballscrew - Troubleshooting Guide
Settings 109-112: This (Setting 109) is the number of minutes (up to 300 minutes from power-up) during which the compensations specified in Settings 110-112 are applied. If your application involves moving a single axis repeatedly back and forth over a small area of the ballscrew, the ballnut will heat up the ballscrew and cause thermal expansion.

Ball Valve - an overview | ScienceDirect Topics
Fluid pressure acting on the ball forces the ball into the seats, giving a tight seal (Figure 4.57). The floating ball is not used in high pressure and large sizes for two reasons. First, the high force of the ball against the seats can deform the seats and affect the low-pressure sealing characteristics of the valve.

A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. Previously in this lesson, a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.

Unlike ball milling where the whole vessel rotates or oscillate/vibrates whilst in operation, the vessel remains stationary in media milling. Movement of the balls is initiated by a stirring or agitating device, often represented by several discs mounted on a central shaft rotating at high velocities, 20 000 rpm and above, within the vessel.
Momentum and Kinetic Energy Before the Tackle in Rugby Union
Thereafter, the ball-carrier and tackler were tracked forward to the point of contact for the 0.5 seconds. Ball-carriers were generally tracked from mid-section (hip area) and tacklers on the upper body (Figure 1). The rationale for this is that during most tackles, tacklers enter the tackle with their upper body as the first point of contact.
