Thank you... how much downward force is on the ropes supporting the ladder?

Yeah, the size of the hole in the ceiling... about 54"

Thanks to all so far. The drawing by Insightful represents what I am planning. I reasoned that lifting one the end of the ladder 72 lb (100") would require 36lbs. This seemed to be supported by an answer elsewhere on the forum...

I think it's actually 63.43 degrees, but my measurements are pretty rough. I used this logic, my height is 90", my run is 45", a**2 + b**2 = C**2= 2025+7975=10,000. Then I used a calculator, although I wish I could remember how to calculate it with paper and pen.

Thanks for the welcome and reply Berkeman... You got my project... currently there is a folding attic ladder to the loft in my cabin that is not durable enough for the traffic. When the ladder is down it will be approx 60 degree slope. When up it will fit horizontally between two 4x6 wooden...

Hi. First Post. I'm a DIYer with no physics education, so I apologize in advance. I have a ladder 100 inches long that weighs 72 lbs. The top of the rails of the ladder are attached to hinges on a ceiling beam/loft floor joist 90 inches above the first floor. The run is 45 inches. I...

Howdy I'm a guy that didn't pay enough attention during math and never took physics in school... but I love learning, fixing, and building. I commonly get involved in DIY projects that may not require math and physics but they sure would make problems easier to solve. Thanks in advance for...
