Gyroscope Definition and 167 Threads

I know when spinning a gyroscope will resist change in orientation so that the rotor is still pointing in the same direction. But, is that direction with respect to Earth's center of gravity or is it an "absolute direction". So, if I point a gyroscope upwards and spin the rotor and I go...

1)i have this problem, we have a toy gyroscope, which its pricnipal moments of inertia are known, spins around its axis of symmetry with angular velocity w, and it's tilt with angle a from the vertical on a smooth table (i.e frictionless table). i need to find the precession frequency? im given...

We know intuitively that a gyroscope in zero gravity (or free fall) can spin almost indefinitely with either a zero or 90 degree precession angle (i.e., spinning perfectly along its axis or along its "side," respectively). Why shouldn't it be able to spin at intermediate states, such as with a...

A demonstration gyro wheel is constructed by removing the tire from a bicycle wheel 1.0m in diameter, wrapping lead wire around the rim, and taping it in place. The shaft projects .2m at each side of the wheel and a man holds the ends of the shaft in his hands. The mass of the system is 5kg and...

After reading in specialized Physics books and different articles, I’m still thinking about gyroscopical precession. I understand everything about angular momentum, torques…, but if center of masses makes a circular movement, Where does it provide centripetal force? Could it be for the axe...

«(...) a torque τ applied perpendicular to the axis of rotation, and therefore perpendicular to L, results in a motion perpendicular to both τ and L. This motion is called precession.»(http://en.wikipedia.org/wiki/Gyroscope) Why does this happen? Assumpting this makes all further calculus...

I was looking at some web sites about the Gravity Probe B. Some show the spin axes of the gyroscopes oriented perpendicular to the Earth or else in the direction of movement of the satelite. Wouldn't these orientations cause lots of precession? I'd expect the gyroscopes' axes of rotation to...

Can anyone recommend a good gyroscope (not too expensive) to purchase?

Consider the concept of a gyroscope. You tie a string to one end and attach the other end to the ceiling so only one end is supported, If you let go when it is not spinning, the obvious occurs - it falls from its horizontal position to a vertical position with the other end pointing towards the...

A gyroscope of a certain size is mounted midship of an SUV of about 2100 lbs, and the gyroscope was setup to accelerate if this SUV accelerated. Now normally if a SUV makes a 90 degree turn past 35 miles per hour the driver looses control and or the vehicle rolls over. How fast would...

I don't understand why a rotating gyroscope whose rotation axis is inclined with respect to a vertical axis does not fall to the ground dues to gravity as fast as the non-rotating giroscope. Thanks for your replies.

A toy gyroscope consists of a M = 2.5 kg disk with a radius of R = 2 cm mounted at the end of a light axle r = 7 cm long. The gyroscope spins at f = 47 rev/s. It is held horizontal at one end of its axle and precesses about its stand as shown. a) What is the angular momentum of the disk...

How does axis of rotation of a gyroscope alter from the geodetic and framedragging effects... and why is the axis pointing in a constant direction in the first place?

In GPB's experimental conditions, a negligible amount of precession takes place. So in terms of rotational inertia, why does the spin axis of a gyroscopes remain pointing in the same direction? Also, why would changes in space-time cause the axis to change? Thanks

Just a few questions I have been trying to find answers to. A) Will a gyroscope function in deep space with the same properties as on Earth ? B) Does sound travel in deep space? if yes in what form of property will it travel? i.e. such as light being a carrier or?

Most of us have played around with gyroscopes, but I think that I have taken it beyond just "playing". I have come to notice that when a gyroscope begins to lose RPM, the top starts wobbling and procedes to spin in wider and wider circles until it clunks to the surface that it is placed upon...

I was playing around with my gyroscope yesterday and laid out a possible Uranian scenario. If Uranus was long ago in a rotation similar to that of Earth's, then an impact that applied a clockwise force (as viewed from a point further out from the planet looking in at its side) would cause a...
