 comment Is tying a knot in an electrical wire safe?
zip ties didn't work. They didn't get tight enough and the wire could pull right through with minimal effort.

@MichaelKjörling I can't find something like this anywhere. If anyone knows of one, please tell me about it

Why isn't it safe, and what is a permanent solution? Thanks

 comment Why is the drywall in my garage sagging?
That sounds like a good idea, to try on a couple sheets at least.

 comment Why is the drywall in my garage sagging?
There's no direct water damage that I can see. The sagging is each entire sheet, not in waves. It's the sheetrock, not the hoists that sag - I'll have to check the span. Can you give me the rule for what thickness to use for what span?

 comment How much load can a (wood) board support, if it is supported only at the ends?
This is a fundamental of anchor building in rock climbing. To be safe we require the angle in the Y to be < 90 degrees, otherwise the attachment points are being pulled inward too much, instead of mostly downward (a load direction that rock climbing bolts aren't set for). The same physics applies here.
