 The assumed form of this relationship is l = A/Pd with Pd expressed in MPa.

 In negotiating curved track, creep forces are generated between the wheels and rails, which attempt to move the axles' radial alignment. In so doing, the truck suspensions are strained.

 The lubricant introduced at the small end is pumped through the bearing to the large end and in doing so is thrown centrifugally to the cup raceway surface thus cooling the cup.

 A careful study of the problem reveals that either h or T must be provided as input and, with that, the solution will yield the other of the two via an iterative procedure which uses the measured temperature on the rear face.

 When done in this way, the grain depth of cut increases from zero at the start of each scratch, reaches maximum values halfway through, and then decreases back to zero.

 At this point, the light source aperture, the cell and white light viewing apertures should be in perfect alignment.

 (Пример случая, когда это русское словосочетание на английский не переводится.) Normally, the heat exchanger can be unpressurised by shutting off the fluid inlets and outlets. The temperature will gradually decrease to the ambient temperature.
