Can someone explain to me how a gyroscope works non-mathematically?

Hi all, Currently, I'm doing an experiment to estimate length of a rigid body. The approach is based on information from accelerometer and gyroscope while the rigid body is moved in circular way. The relationship is: v = ω x R (all are vectors, and 'x' means cross products) v =...

I was hoping someone could clear this up for me. I've been thinking about it a bit, and I am thoroughly confused. Here is what I have come up with so far. The situation: A horizontal (wheel vertical) gyroscope spinning counter clockwise held up at one end by a string. Now change views so...

Hi, y'all; This will likely be a simply question for most of you, but I am still something of a neophyte (yes, yes, starting off with the whole education thing in my 30's -- egad!) but if I were to reverse the current running through a MEMS gyroscope, what would be the outcome in the figures...

The angular speed of precession for a gyroscope is given by ω_{p} = T/ω_{g}. So that the rate of precession increases as the gyroscope, top, or wheel slows down. This agrees with observations of a top, which wobbles around very quickly as it slows down. If I hold a bicycle wheel in my...

Hello, I think what i have is a simple question and yet it is not answered by most of the articles on gyroscopes. I am wondering how I can calculate the amount of resistance a gyroscope develops to an applied torque on the primary axis when the secondary axis is fixed. Ie, torque is...

Hi ! I have very basic question about gyroscopes: do I need same torque from gimbal motor to accelerate the flywheel whenever it's rotating or not ? (and the gimbal motor is attached to the floor) Thanks in advance :)

Hi ! My name is Max and I'm a Mechanical Engineer. I'm working on Control Moment Gyroscope project, but because for a long time I didn't deal with theory, I'm stuck at some very basic dynamics problem. In this article http://www. spacecraft research.com/files/BrownPeck_JGCD2009 the author writes...

my textbook says: "As a gyroscope precesses, its center off mass moves in a circle with radius r in a horizontal plane. Its vertical component of acceleration is zero so the upward normal force exerted by the pivot must equal mg." Now wouldn't this always be true. I mean if u have a...

Homework Statement The Hubble Space Telescope is stabilized to within an angle of about 2 millionths of a degree by means of a series of gyroscopes that spin at 1.92×104 . Although the structure of these gyroscopes is actually quite complex, we can model each of the gyroscopes as a thin-walled...

Dear All This is a rather strange question for you one that i can find no conclusive argument to. when riding a large motorbike i am informed that the engine must be reved at low speeds in order to keep the engine spinning at a sufficient speed to enable it to generate a strong enough...

Hey I just finished an experiment in my physics lab where we examined the precession and nutation of a gyroscope. The gyroscope was built with a shaft which had a pivot in the middle, on one end of the shaft the large spinning disc was placed and on the left side of the shaft...

Gyroscope doubts. Please answer :) Consider the case of a common demonstration which you would find in videos. A bicycle wheel mounted on a shaft is set into rotation, axis is made horizontal and the shaft stays horizontal for sometime and eventually goes down as the wheel spin slows down due...

I am studying the influence of a gyroscopic effect of wheels/tyres on a steering system in a car. I can't seem to get my head around few concepts. It boils down to a simple problem. Consider a free spinning gyroscope wheel with horizontally aligned axis. This axis is mounted in a vertical...

Hey guys, I recently did a project with combining and accelerometer and gyroscope together using the 6DOF IMU Razor and an Arduino and now i need to try something different but i need some help. How does one integrate a gyroscope output? I tried something like this below but i don't think...

This question on my final blew my mind and I have no clue where to even start: (verbatim, not exact wording and so 'theoretical' I almost posted it under relativity) Given that an observer on Earth with acceleration due to gravity 9.8 m/s^2 has an indestructible frictionless gyroscope and a...

Homework Statement The rotor (flywheel) of a toy gyroscope has mass 0.150 kg. Its moment of inertia about its axis is 1.20*10^- 4 kg m^2. The mass of the frame is 2.70×10−2 kg. The gyroscope is supported on a single pivot with its center of mass a horizontal distance of 4.00 cm from the...

Hi Guys, Most of you guys should heard of Fibre optic gyroscopes. I'm trying to create a gyroscope that send out microwave instead of light source. Is there any program that i can use to create the circuit and simulate before getting hands on. Btw it might or might not work i have no idea...

The bend in space-time due to Earth's gravity was measured by a gyroscope. A bend in space-time causes even light to bend, how does a gyroscope escape this? The angular momentum being discussed in a gyroscope, is this the same as the one we call "spin" in the entangled photons/electrons?

Wikipedia says that a gyroscope is based on the conservation of angular momentum. This whole day I'v been doing my report on gyroscopes and explaining their precession. But how do I connect the conservation of angular momentum to this? I don't know where to start. I have seen videos...

This is not a homework question, but from having read the rules in the following thread, it looks like this is more academic assistance than pure discussion: https://www.physicsforums.com/showthread.php?t=414380 So anyhow, I am having real trouble with precession. I know that net torque is...

can anyone please explain me following errors of gyroscopes used in inertial navigation systems of aircraft : a) what is transport wander , how actually it happens ? b) what is apparent drift in gyroscope ? c) what is coriolis effect and how it causes errors in gyroscopes ?

hello all.. Iam using LPY5150AL Breakout gyro. I have connected to a PIC16F877A microcontroller.The problem is that iam getting outputs of gyro around 1100 -1300 deg/sec when i rotate the axes.I don't know whether these values are correct are not??can anyone help me out..! The formula used is...

im trying to implement a tilt sensing program via accelerometer and gyroscope. part of the input that i will plan on using is gyroscope data. since gyroscopes measure angle/sec, integrating this will give me angle right? i then have three questions: 1. do i multiply the gyroscope's (1/sampling...

Today in class we have an intro to gyroscopes where my professor gave the classic "bicycle wheel" example where he spun a bicycle wheel to give it significant angular velocity, attached one end of the wheel apparatus to a string fixed to the ceiling, and let the wheel hang and precess (just like...

1. I am carrying a briefcase in which sits a gyroscope whose large angular velocity points forward horizontally. When I try to climb stairs, what happens to the briefcase? 2. 0=\Delta\vec{}L 3. My intuition says that the briefcase would point downward, but I really don't know how to approach...

I need to build a working gyroscope. Where can I find information on how to build one? also what materials to use to build it? Any Ideas?

Hi friends I read about gyros and read their working and analysis based conservation of angular momentum. I understood it as I was made to by the analysis but i didn't find the real reason why gyro shows such a behaviour. I mean what forces it to do the magic it does? Is there any analysis...

Hi, I am an engineering student that needs help using an accelerometer and a gyroscope. I'm not sure where to begin. How can I setup the sensors to output readable data to a computer. Do I use a microcontroller? Do I need to program anything? I am just in need of help. Anything would be...

I ran a search for gyroscopes looking for a definitive solution to the "What causes Precession?" and found no good clear answers. I think the Feynman lectures come close to the solution and followed that thought process, all the pieces point to the solution, I had to put my theory to the test on...

Hi everybody, I think that I understand how classical gyroscopes work. But I can't understand how solid-state gyroscopes work. I have searched the internet for a good explanation of their principle of operation for several days but I've found nothing. I just don't see any relation between a...

Hey, while reading Kleppner & Kolenkow's discourse on gyrocompasses, I ran into a statement I could not wrap my head around: "The pivots at A and B allow the system to swing freely about the y axis, so there can be no torque along the y-axis." AB is an axis along the y-axis, which is the...
