Accelerometer Definition and 158 Threads

Hi, please don't hesitate to reply to either of my paragraphs. Or ask for clarification. The first paragraph descibes the basic problem, and the second one is more indepth. I'd be happy if I could get just the first one working. I'm working on a project were a two-axis accelerometer will...

Dear everyone, this is my first post here. Nice to meet you all. Now I have my project to design a catilever which can be used as accelerometer. The current stage is to have the vibration motion of the cantilever formulated using FEM, and then the design parameters can be substituted into the...

ok, Don't know if this is the right forum, but I'd like some help with this I'm making a project that needs to read acceleration in any direction. I have a 3 axis accelerometer, who's orientation is random, unknown, and changing. So my question is, is it possible to read 2 forces of...

correct me if wrong an accelerometer consists of a mass(proof mass). say the proof mass is x kg. The accelerometer sensed the acceleration of the proof mass. suppose the accelerometer reading is y can i say the force acting on the proof mass is x.y? Some theory says that the...

How would I go about measuring forward acceleration using a free-swinging ball on a stand? Could anyone post a free body diagram or an equation that might describe this?

I need help with this say there's a truck travellin at a constant speed along a winding flat road. the car body is connected to the axles with springs. Thus, the car body is assumed to roll at a 10degree angle from the vertical of a horizontal 'roll axis' which is fixed on the axles. An...

hello, I'm using an accelerometer (ADXL311) which outputs analog voltage in proportion to g's for X and Y axes. I'm trying to use this to manipulate sound when a person is 'running', basically as speed increases above a certain threshold, but having problems with my formulas for speed...

A person dangles her watch from a string while the plane takes off. She notices that the string makes a angle of 25 degrees with respect to the vertical whie the plane accelerates to take off, which takes 19 seconds. What is the takeoff speed of the plane? How do I get started? I think the X...
