Z coordinate of the center of gravity

Click For Summary

Homework Help Overview

The discussion revolves around finding the z coordinate of the center of gravity for a cylinder or disk, which is oriented with its height along the y-axis and extends in the z direction. The original poster seeks clarification on the appropriate equation for this calculation.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the concept of the center of mass for a uniform cylinder and whether the z coordinate can simply be identified based on the cylinder's orientation and dimensions. There is a suggestion to consider the height and position of the cylinder in relation to the z axis.

Discussion Status

The discussion is ongoing, with some participants providing insights about the center of mass while others are questioning the specifics of the problem setup. The original poster is exploring the implications of the cylinder's dimensions on the z coordinate.

Contextual Notes

The original poster mentions specific measurements for the cylinder, including a height of 10 mm along the y-axis and an extension of 105 mm in the z direction. There is also a reference to an image intended to clarify the problem, which did not display correctly in the previous post.

Hey,

for this problem i need to find the z coordinate of the center of gravity. I have a cylinder/disk whose height is along the y-axis and radiates about the x and z axis. what is the equation to find z bar. this is just one part of the problem.

Perhaps I don't understand your question, but the center of mass of a uniform cylinder is right in the middle.
 
yeah i get that much, but for this problem it wants me to find the z coordinate for the center of gravity. and the cylinder is oriented 105 mm in the z direction, with a height of 10 mm going in the y direction.

Here is a pic that hopefully gives some clarification. I apologize for the crudity of it, I made it on paint.

hmm...my image didn't show last post.

hmm...thinking about it, would the z coordinate just be 105mm?
