When speed is doubled, the centrifugal (or centripetal) force increases by a factor of 4. One formula you can use (for centripetal acceleration) is: a = v2 / r. Force, of course, is proportional to acceleration.

What is a centrifugal force tachometer?
THis type of tachometre is also knowm as flyball tachometre. The basic principle of this tachometre is that the centrifugal force is directly proportional to the shaft speed . Two fly-balls whose weights are small are used in this tachometre and hence it is called flyball tachometre . These two balls are used in developing centrifugal force. In this case the spring is compressed as function of shaft speed. It is noted that one end of the spring is connected to the sleeve and moved smoothly on spindle . The position of the sleeve is indicated as the speed of rotating shaft. The motion of the sleeve is amplified and it indicates the speed with the help of a pointer on scale. This type of tachometer is also used for linear speed measurements , with necessary attachments mounted on the spindle . For obtaining speed over wide range , this type of tachometer uses multiple range units. A gear train is used between the fly balls to complete the change from one range to another range . The draw back ofthe tachometer is overspeed which seriously damage the instrument . This type of tachometers are widely used for measuring of shaft speeds upto 40×10^3 rpm . Its accaracy is + or - 1% of full scale.
What are the three main part of single-phase motors?
The main parts are the stator and the rotor.After that depends on the type of single phase motor. This includes capacitors (start and/or run),centrifugal switch (stationary and rotary) Also there are usually two windings,a start and a run winding. In its most basic form the start and run winding are connected together at one end of the windings (common) the other end of the run winding connected via a centrifugal switch and/or run capacitor to the other end of the start winding. Power is supplies to the run winding terminals. The start capacitor is fitted in series with the centrifugal switch, allowing it to be disconnected once rotation speed is reached.
Do you prefer a centrifugal compressor over a screw compressor?
Screw chiller running with a male & female blade,Centrifugual chiller running with an impeller. Screw chiller are very reliable on more load like more than 200 tr ,its less consumption comapare to other chillers.
What happens to the speed of motor while the excitation current is decreasing?
Assuming there is no mechanical load, as the speed approaches the synchronous speed the slip decreases and the current induced in the rotor also decreases. The stator coil begins to approximate a pure inductor and that causes the current to fall. In the steady state the power drawn is used to overcome friction in the bearings and windage only.
When the angular speed of an object increase its angular momentum may or may not increase?
if the angular speed of an object increase its angular momentum will also increase
What are the practical example of centrifugal force?
Centrifuge separation of masses is a practical example of centrifugal force; also discus throwing and finally the rotation of the earth around the sun involves a centrifugal force.
What is a push force?
centrifugal force is also called as push force and centripetal is pull force
Picture a ball traveling at a constant speed around the inside of a circular structureis the ball accelerating?
If it's going at a constant speed then it is not accelerating. To accelerate would mean to have a rate of change for speed in some direction. If the ball is going outward while traveling at a constant speed due to centrifugal force then it is accelerating. If it's going inwards due to some ground angle then it is also accelerating. From Newton's laws we know that to have a circular motion, an object must be subject to a force directed to the centre of the structure and is accelerating in that direction. This centrifugal force, exerted by the structure to the ball, is opposite in direction and magnitude to the 'fictitious' centrifugal force.
Can centrifugal force be balanced by coulomb force in an atom?
It can, but other forces (like the Strong Nuclear Force) also balance out the electromagnetic force. This gets into quantum mechanics, and the centrifugal force doesn't really apply a whole lot.
Is centripetal force also called an inward force?
Yes. Centripetal is center seeking force. Centrifugal is center fleeing force.
The type of force that keeps objects moving in a circle or arc?
The type of force that keeps an object such as the Earth moving in a circle is a combination of gravity and centrifugal force. Gravity wants to pull the object inward, but centrifugal force wants to push the object outward. This combination keeps objects going in a circular path. You could also say that, for objects such as a rock attached to a rope that is swung in circles, the forces are the tension of the rope opposing centrifugal force. This is essentially the same thing, except with different forces at work.
If you double the rpm will the speed also double?
No
What causes the space shuttle to stay in orbit?
The reason the Space Shuttle (or any other orbiting object) stays in orbit is a combination of centrifugal force and falling. Basically, the object is constantly falling due to gravity. However, it's also traveling around the planet and the centrifugal force of that travel is equal to the gravity causing it to fall. This is why inside the craft is weightless, gravity is negated by the force. This is also why some objects fall, their orbit and speed are not matched 100% to the force of gravity, so they slowly fall into the earth. This is also how shuttles and other ships come back to earth, they slow their orbit and gravity takes over!
Why should you slow down when driving through a curve?
The speed of the racing cars get increased by a driver,, because it is always applied that all curves in racing roads are banked to provide appropriate centripetal force,,and through this there's maximum speed which shouldn't exceed during turning on the corner!!
What is a force produced by a circular motion that causes something to accelerate?
Circular motion doesn't produce force. 'Centripetal force' is necessary in order to produce circular motion. Also, so-called 'centrifugal force' isn't a force at all.
Is a centrifugal force the same as the centripetal force?
Answer: no..while centrifugal force is about something going away from the center of rotation, the centripetal force means getting pulled towards the center of circle. Answer: Also, the centripetal force is a real force, while the centripetal force is a ficticious force - or a force that only appears in a rotating frame of reference. For purposes of calculation, the magnitude of both forces is the same, and same formulas can be applied: F = ma, and either a = v2/r, or a = omega2 x r.
How many times the centripetal force will increase if the mass of a body moving with uniform speed in a circle is doubled?
It will also double, according to Newton's Second Law.
