Relative speed

As load is increased and relative speed is decreased, the film between the two surfaces becomes thinner, and increasing contact occurs between the surface regions. The coefficient of friction rises from the very low values possible for fluid friction to some value that usually is less than that for unlubricated surfaces. This type of lubrication, that is, where the nature of the surface region is... 

In the Lab frame, the projectile is scattered by 0 and the target, originally at rest, recoils tlirough angle 9g. The number of particles scattered into each solid angle in each frame remains the same, the relative speed v is now and j- = N v in each frame. Hence...

The magnetic field rotates at a synchronous speed, so it should also rotate the rotor. But this is not so in an induction motor. During start-up, the rate of cutting of llux is the maximum and so is the induced e.m.f. in the rotor circuit. It diminishes with motor speed due to the reduced relative speed between the rotor and the stator flux. At a synchronous speed, there is no linkage of flux and thus no induced e.m.f. in the rotor circuit, consequently the torque developed is zero. 

In the case of parallel reactions, the fastest reaction will set or control the overall change. In all rate determining cases, the relative speed of the reactions will change with the temperature. This is caused by different energies of activation among the steps in the sequence. This is just one more reason for limiting rate predictions from measurements within the studied domain to avoid extrapolation. 

Generally, these oeeur simultaneously. The relative amount of ethylene and aeetaldehyde obtained therefore depends on the relative speed of the two reaetions eompeting with eaeh other for the available aleohol. These speeds, in turn, are determined by the ehoiee of eatalyst and temperature.

An internal spur gear, in combination with a standard spur-gear pinion, provides a compact drive mechanism for transmitting motion between parallel shafts that rotate in the same direction. The internal gear is a wheel that has teeth cut on the inside of its rim and the pinion is housed inside the wheel. The driving and driven members rotate in the same direction at relative speeds inversely proportional to the number of teeth. 

Relative speed between the inner and outer race (rps). 

The relative rates of effusion of different gases depend on two factors the pressures of the gases and the relative speeds of their particles. If two different gases A and B are compared at the same pressure, only their speeds are of concern, and...

The collision frequency is greater the higher the relative speeds of the molecules, and therefore the higher the temperature. 

Although the mean relative speed of the molecules increases with temperature, and the collision frequency therefore increases as well, Eq. 16 shows that the mean relative speed increases only as the square root of the temperature. This dependence is far too weak to account for observation. If we used Eq. 16 to predict the temperature dependence of reaction rates, we would conclude that an increase in temperature of 10°C at about room temperature (from 273 K to 283 K) increases the collision frequency by a factor of only 1.02, whereas experiments show that many reaction rates double over that range. Another factor must be affecting the rate.

We can rotate the crucible by itself, or in conjunction with the crystal. But another complexity arises, namely what direction of rotation and what relative speed of rotation should we use for both, or either If we rotate the crystal clockwise and the crucible counter-clockwise, then the heat flow patterns become complex indeed. These complexities have been studied in detail but will not be enumerated here.

We control fiber properties by changing the relative speeds of different stages of the process. Orientation is increased and fiber thickness decreased by increasing the final take-up speed relative to the rate at which the molten polymer strands leave the spinneret. To produce high modulus fibers we generally adopt conditions that maximize orientation. Fiber diameters...
