Okay, so, I'm doing a DIY home improvement project; I do not have access to the attic as my home is on the second floor of my building.
The project: Installing a beaded ballchain/shimmerscreen curtain that will serve as a partition. The rod from which several chains will be suspended from is 78 1/2" long. The net weight of beaded ball chains that will hang from the rod is +/-70lbs and will be distributed evenly across 78 1/2".
For clearer concept, look here: http://www.shimmerscreen.com/portfolio.html
Is it reasonable to attempt to install 70lbs worth of beaded curtain across 78" given that my home's has drywall ceiling is 1/2" thick? Now, lay into me!
And sorry, more genius which a different aspect of engineering (computers/IT).
