Hi Frank:
In most cases, the COG is near or at the geographic center of the
equipment. This would be at the half-way point of each dimension, W, L,
H. For your product, the worst-case tip-over would be on the W (5 feet)
side.
Expanding on Doug's suggestion, tip the unit on each bottom edge to the
balance point. Have an assistant with a chalk line and plumb bob snap a
chalk line from the pivot point. Repeat for all bottom edges.
Using this data plus an outline of each side of the equipment, you can
plot the data to determine the intersection of all (4?) chalk lines,
which is the COG.
On the other hand, you can hand the equipment over to UL, Milpitas, who
will determine the tilt stability. For an extra fee, they will
determine the COG.
Good luck,
Rich

A quick and dirty way to find the center of gravity is to hang the
product from each of the four corners on top, one at a time. For
example from lifting rings or similar. The imaginary vertical lines
that passes through the product should all intersect at the COG.
Similarly, you could simply tilt up to the balance point on all four
edges and the four imaginary vertical planes will intersect at the COG.

Hi Everyone,
I have been searching and drawing blanks for test labs in the bay
area capable of performing tilt stability and measuring center of
gravity in bay area California, San Jose, Fremont, Santa Clara,
Sunnyvale, etc.
Is there a lab or facility someone in this community uses to
perform such testing and measurements for large scale equipments,
5 feet (w)× 6 feet (l)× 7.5 feet (h)?
