    Acceleration Data
AI Thread Summary
To calculate lateral and longitudinal acceleration from the provided 3-axis acceleration data, it's essential to first remove the gravity component, which requires knowledge of the vehicle's orientation, typically represented by Euler angles. The discussion highlights the need for a method to isolate actual acceleration values in m/s² by accounting for gravitational effects. Participants emphasize the importance of understanding the vehicle's orientation to accurately adjust the acceleration data. Without this orientation information, calculating true acceleration values will be challenging. The conversation underscores the necessity of integrating orientation data for precise vehicle performance analysis.

Hello all,
i have some acceleration value s in each axis(x,y,z)
i want to calculate the acceleration and de-acceleration using the acceleration data in (m/s^2)

my data are as below:-
id time (ms) x (m/s2) y (m/s2) z (m/s2)

How i will calculate the lateral and longitudinal acceleration (vehicle performance)

how to remove the gravity factor to get the acctual acceleration

thanks in advance

Regards

You need to provide a basic description of what it is you're doing here. If you want to remove gravity components you need to know the body orientation (Euler Angles), which I do not see.

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
