If electrons ' move ' about the electron cloud in strict paths the same way planets orbit the sun, then electrons would be required to do so at speeds which far exceed the speed of light.

If rotary pumps are operated at high speeds, the fluids will cause erosion, eventually developing enlarged clearances through which liquid can pass, reducing the efficiency of the pump.

If they were at different speeds ( different frequencies ), the phase difference is undefined and would only reflect different starting positions.

If wormholes are possible, then ordinary subluminal methods of communication could be sent through them to achieve superluminal transmission speeds.

If these tail adaptations were for balance and stability while turning, especially at high speeds, it wouldn ’ t explain why other predatory theropods lacked them.

If its leading edge is raked back enough, it will escape the shock wave formed at the nose of the aircraft as transonic speeds are reached, reducing drag considerably, and the center of lift moves less than on conventionally configured aircraft, reducing trim drag.

If every shared library that is loaded has undergone this process, then each will load at its predetermined address, which speeds up the process of dynamic linking.

If the engine is running at a constant speed, the rotational speed of each driving wheel can vary, but the sum ( or average ) of the two wheels ' speeds can not change.

" However, this positive message about the innocuous-seeming toy was undercut by a much lengthier number of bizarre disclaimers and warnings, including " may suddenly accelerate to dangerous speeds " and " If Happy Fun Ball begins to smoke, seek shelter and cover head.

If the balls fall in a vacuum, then there's no air resistance and their final speeds will be the same.

If its airspeed was insufficient, and particularly if its high-lift devices were not extended at the low speeds typical of climbing away after take-off or of approaching to land, it could enter a deep stall ( or " superstall ") condition, in which the tail control surfaces become ineffective ( as they are in the turbulence zone of the stalled main wing ) from which recovery was practically impossible.

If the pressure gradient is large enough, the dry offshore wind can become quite strong with gusts reaching speeds of or higher, particularly along and in the lee of the ridges of the Coast Range where the higher wind speed aloft acts like a pump, drawing warm, dry surface air from the windward eastern side up and over the ridgelines.

If robots remain in the maze Otto moves slowly, about half as fast as the humanoid, but he speeds up to match the humanoid's speed once all the robots are killed.

If it is, then many things that we would normally consider to be demonstrably impossible can be logically possible: for example, that travel might be possible at speeds faster-than-light or that escape from black holes is not impossible.

If a stage is reached where irrespective of the amount of practice, typing speed is not increasing, it is advisable to let some time pass and continue serious practice thereafter as typing speeds typically tend to increase with time even when no serious practice is done.

If two of the PGS rotator speeds are the input and output of the CVR, there is a setting of the CVR that results in the IVT output speed of zero.

If the teeth, the so-called dog teeth, make contact with the gear, but the two parts are spinning at different speeds, the teeth will fail to engage and a loud grinding sound will be heard as they clatter together.

If the electron beam is used to cut a shallow trough in the surface, then repeatedly moving horizontally along the trough at high speeds it creates a small pile of ejected melted metal at the end of the trough, Upon repetition spike structures can be created up to a millimeter high.

If the building's tuned mass damper went offline, the necessary wind speeds were predicted to occur every 16 years.

If wind speeds are forecast to be higher than 34 miles per hour, all balloons are removed from the parade.

If the sphere is moving at relativistic speeds ( that is close to the speed of light, shown on the right ) then we would observe these same photons to be emitted from a cone centered around the direction of motion.

If the locomotive's engineer does not detect and rectify this situation at once two things will occur, first, the metal tires that surround the driving wheels will be seriously damaged ; second, the piston rods, their bearings and the other equipment associated with the reciprocating motion of the engine will be overstressed and destroyed ; the engine will literally tear itself apart, by its operation at speeds well beyond the design limitations.

If variables such as cutter geometry and the rigidity of the machine tool and its tooling setup could be ideally maximized ( and reduced to negligible constants ), then only a lack of power ( that is, kilowatts or horsepower ) available to the spindle would prevent the use of the maximum possible speeds and feeds for any given workpiece material and cutter material.

If it does happen, then material reaching the bottom of the convective thrust region can no longer be adequately supported by convection and will fall under gravity, forming a pyroclastic flow or surge which can travel down the flanks of a volcano at speeds of over 100 km / h.

If it were not for an old professor who made me read the classics I would have been stymied on what to do, and now I understand why they are classics ; ;

If I even hint at it do you think it will matter that you are his nephew -- and not even a blood nephew ''??

If the circumstances are faced frankly it is not reasonable to expect this to be true.

If his dancers are sometimes made to look as if they might be creatures from Mars, this is consistent with his intention of placing them in the orbit of another world, a world in which they are freed of their pedestrian identities.

If love reflects the nature of man, as Ortega Y Gasset believes, if the person in love betrays decisively what he is by his behavior in love, then the writers of the beat generation are creating a new literary genre.

If to be innocent is to be helpless, then I had been -- as are we all -- helpless at the start.

Defoe then commented, `` If they Could Draw that young Gentleman into Their Measures They would show themselves quickly, for they are not asham'd to Say They want only a head to Make a beginning ''.

If Jews are identified as a religious body in a controversy that comes before a national or international tribunal, it is obviously compatible with the goal of human dignity to protect freedom of worship.

If they are right, they will prevail of and by themselves.

Without preliminaries, Esther asked him, `` If you are a world citizen, will you take Garry Davis' place in his tent while he goes to the hospital ''??

If we are to believe the list of titles printed in Malraux's latest book, La Metamorphose Des Dieux, Vol. 1 ( ( 1957 ), he is still engaged in writing a large novel under his original title.

If the would-be joiner asks these questions he is not likely to be duped by extremists who are seeking to capitalize on the confusions and the patriotic apprehensions of Americans in a troubled time.

If we break the minister to our bit, we are buying back our own sins.

If the record buyer's tastes are somewhat eclectic or even the slightest bit esoteric, he will find them satisfied on educational records.

If Daddy's books are out of bounds his own picture books are not.

If it will simply delay the debates until the qualifications are closed next spring, and then carry all the candidates on a tour of debates, it can provide a service to the state.

If they are to be commended for foresight in their planning, what then is the judgment of a town council that compounds this problem during the planning stage??

If the Communists are sincere in wanting a united, neutral and disarmed Germany, it might well be advantageous for the German people in this nuclear age.

If only this could be done more often -- with such heartening results -- many of the earth's `` big problems '' would shrink to the insignificances they really are.

If any are left, presently, we may expect to see signs specifically prohibiting the feeding of them too.

If the raw population figures are crucially relevant, then it is idle to think of liberation, as idle as to suppose that Poland might liberate Russia.

If it is not enough that all of our internationalist One Worlders are advocating that we join this market, I refer you to an article in the New York Times' magazine section ( Nov. 12, 1961 ), by Mr. Eric Johnston, entitled `` We Must Join The Common Market ''.

If the UN troops are not mercenaries then the Hessians were not mercenaries either.
