Homework Help: Z coordinate of the center of gravity

  1. Oct 13, 2008 #1

    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.

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution

    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?
