### Dynamics of pendulum coupled to a gyroscope [on hold]

We know the dynamics of a pendulum and we know the dynamics of a gyroscope. I put together the following I diagram below. The interesting thing as that the system has a beat frequency where the ...

### 3 gimbal gyroscope stability

Apologies if this has been answered elsewhere but I´d rather put my trust in a dedicated community before youtube or wikipedia. Once the rotor/flywheel is up to speed the rotation and centrifugal ...

### How to get correct yaw from a rolled Gyroscope

I have used an smartphone to get three dimentional gyroscope values. Their units are radians per second. I used integral of Z to measure the yaw. But it only works correctly when my smartphone is ...

### Pointer to reference for rotational dynamics for large torques?

It's my understanding that when dealing with rotational dynamics (e.g., a gyroscope like at time=2155 seconds of https://youtu.be/N92FYHHT1qM?t=2155) that the equation for relating the speed of ...

### Gimbal Lock: why is it a problem?

I was watching this video http://www.youtube.com/watch?v=rrUCBOlJdt4 about the gimbal lock problem. I understood that during rotations it could happen that one DOF disappear. Looking at the middle ...

### Can an accelerometer be used to determine orientation of a rocket under power?

I saw a project on Hackaday featuring a model rocket with moveable fins to stabilize the rocket's trajectory: Hackaday. The goal was to arc the rocket to a horizontal trajectory and keep it there. In ...

### Could gyroscopes be use to control orientation of satellite?

In the game space engineers, the player can control the angular movements of a spacecraft with gyroscopes. Just to be clear, the purpose of this gyroscope is not to measure rotation, but to actually ...

### How to explain gyroscopic precession in a more intuitional way?

When Studying the phenomenon of precession a classic example installation is this: a wheel spins around the Y axis, gravity applies and the upper part starts spinning around the Z axis. The textbook ...

### How to calculate the forces that create precessing motion of a spinning top?

I'm trying to create a a spinning top simulation, and I have a problem with simulating the precession. I read the Wiki article about precession, which have the formula for angular velocity of ...

### Gyroscope is not in center of the mass

I have a controller with a MEMS gyroscope on it. Is there any difference if I put gyroscope not in center of the mass? Will be gyroscope drift increase?

### What kind of unit is $m^2s^{-4}$ in terms of gyro/accel?

Background While working on something in the field of avionics, I have discovered the following unit as part of an inertial-physics equation... $$m^2s^{-4}$$ I am trying to figure out the formal ...

### How to get speed of a train without using GPS

How can I measure instantaneous speed of a train in which I am travelling without using GPS/location services? The train can start underground or can start from ground level (where GPS is available) ...

### Could a gyroscope demonstrate absolute motion?

If a spaceship were moving very fast, and a rocket motor mounted perpendicular to the direction of motion/"main thruster" were turned on, the change in direction to an observer would be proportional ...

### planetary scale motor

A spinning mass of a motor has a gyroscopic effect when moved. As the mas and size of the motor approaches the size of the planet it sits on, what kind of effects would this cause to the planet?

### Which force acts as centripetal force on gyroscope?

I think I have understood gyroscope in terms of angular momentum and how the torque of gravitational force moves it the way it does. Also I understand the direction in which it would move: What ...

### How do I work out the needed speed of the rotors in a Dual Gimbal CMG, as well as the needed tilt angle; for an object to maintain balance? [closed]

I've been looking at methods of self-balancing an object and came across this: http://litmotors.com/c1/. I was wondering how one would calculate the needed speed of each rotor to rotate at, and the ...

### What exactly is a torque?

I know there are a number of questions concerning torque on this site but I still don't quite understand what it is. A video by veritasium on gyroscopic precession (http://www.youtube.com/watch?v=...

### Gyroscope precession

I have a system diagrammed and explained in the image below. Experimentally I believe the wheel will rotate around the pivot point where the cable is attached in a counter-clock motion if ...

### The precession component in the direction of spinning

Is the precession increasing the rotation around the axis of spinning? w = (nutation) i + (precession component) j + (another precession component + spinning) k or to rephrase, is the precession ...

### Gyroscope: rigidity in space & precession [duplicate]

I understand that a spinning gyroscope creates rigidity in space by resisting forces being applied to it... But, what are the forces resisting the applied forces, and how are hey created? Is that what ...

### If gyroscopes are used as resistance devices, where does energy put in go?

If two gyroscopes were to be started with parallel angular momentums, linked by a rotating tube (one perpendicular to the axle), then a second pair added that is the exact reverse such that it has ...

### Would a double gyroscope still have gyroscopic properties?

Imagine you have a gyroscope that has two spinning parts, one on top of the other. When you pull the string, the two halves spin in opposite directions. Would this cancel out the gyroscopic properties,...
