If a rotating frame is chosen so that just the angular position of an object is held fixed, more complicated motion, such as elliptical and open orbits, appears because the centripetal and centrifugal forces will not balance.

If the spheres only appear to rotate ( that is, we are watching stationary spheres from a rotating frame ), the zero tension in the string is accounted for by observing that the centripetal force is supplied by the centrifugal and Coriolis forces in combination, so no tension is needed.

If a secondary body orbits a primary body, the forces that could tear the second body apart if its strength and internal gravity are not enough, are the tidal force and the " centrifugal force " associated with any rotation of the secondary body about its axis.

If you see all the stars were whirling around you, Mach suggests that there is some physical law which would make it so you would feel a centrifugal force.

If a bucket is filled with water, and made to rotate, initially the water remains still, but then, gradually, the walls of the vessel communicate their motion to the water, making it curve and climb up the borders of the bucket, because of the centrifugal forces produced by the rotation.

If the engine slows down, the centrifugal force reduces and the weights are pulled inward by spring pressure, and this movement is used to increase the engine power to maintain speed under increasing load.

The rate of centrifugation is specified by the angular acceleration applied to the sample, typically measured in comparison to the g. If samples are centrifuged long enough, the particles in the vessel will reach equilibrium wherein the particles accumulate specifically at a point in the vessel where their buoyant density is balanced with centrifugal force.

If one considers an isolated particle circling in the upper cylindrical component of the cyclone at a rotational radius of from the cyclone's central axis, the particle is therefore subjected to centrifugal, drag and buoyant forces.

If we view the particle in a frame of reference moving with the fluid, we can describe the behavior of the particle by invoking the imaginary, inertial centrifugal force acting as a form of gravity directed outward, away from the axis of rotation.

If a temperature rise of 15 ° F ( 8 ° C ) is accepted in the casing — minimum flow through a centrifugal pump can be calculated as

If you draw your fingers through them they are lodged and struggle with a shock of wet heads ; the long stalks rub and click and flatten to a fan on one another like your fingers themselves would when you passed the palms hard across one another, making a brittle rub and jostle like the noise of a hurdle strained by leaning against ; then there is the faint honey smell and in the mouth the sweet gum when you bite them.

If the aircraft burns a large percentage of its fuel with the afterburner alight, it pays to select an engine cycle with a high specific thrust ( i. e. high fan pressure ratio / low bypass ratio ).

If, however, the afterburner is to be hardly used, a low specific thrust ( low fan pressure ratio / high bypass ratio ) cycle will be favored.

If it turned out that I was popular among some bastards, I would feel sad ", wrote Letov on his web site in response to a fan who complained that Grazhdanskaya Oborona was getting too popular.

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.
