Homework Statement
I would like to find a general equation for calculating the centre of gravity (COG) of a hollow conical frustum.
Homework Equations
Consider a solid conical frustum as shown below:
The COG of this shape may be derived as follows:
COG = (h/4)[(b^2+2(ba)+3a^2)/(b^2+ba+a^2)]
Unfortunately, I can't seem to determine a similar equation for a hollow conical frustum
The Attempt at a Solution
I have been able to find the COG for a hollow conical frustum by splitting the shape up into a large number of hollow cylinders, calculating the total moment about the base axis and then divideding by the total weight. To speed things up however, I was hoping that somebody might help me determine a general equation similar to that shown above. I searched through the previous threads, but everything I found related to a either a solid conical frustum or a hollow cone.
Kind Regards,
Dave
