Any help will be greatly appreciated.
Simple representation of the problem is the analysis of the forces and reactions of a table with a non-centered weight on it. I am seeking the reaction forces at the four legs.
Specifics...
Table width - 48"
Table length - 72"
Table height - 36"
Total weight of table and load is 250 lbs.
C.O.G. of all weight is...
x=32" (width)
y=26" (length)
z=28" (height)
I need to determine, from this loading, how much force each of the four legs exerts on the floor.
I have summed forces, summed moments, and come up with 3 equations and four unknowns. How can I get to the answer?
Thanks in advance for any efforts to show me how to do this. I have an ME degree but please make no assumptions of prerequisite knowledge. I'm afraid it has been long forgotten. Please spell it out for me if you can.
