You raff yuo roose v.3871

Making an a frame with two ladders is a pretty common painter’s trick although somewhat sketchy. All they did was add a top ladder to make a scaffold to walk across. Definitely need that middle ladder or else the long ladder would just fall against the roof.

This is why they shouldn't hand out engineering degrees online.

Obviously without the middle ladder the long ladder would push down to the guttering and the top one would either slide backwards if tied at the top or drop forwards and slide off the roof.

:rofl: Not that this was really worth a debate, but I feel compelled to call out retardation when it's so evident.

How/is it attached was the question, retard, not "how do lateral forces work?" I literally said that in the single sentence you quoted: "...unless it's supporting (tied to?) the long one perpendicularly." What part of the house is in the perpendicular direction of the ladder? What is a perpendicular force? Derr.

Your response almost completely mirrors what I said, only you point out the fact that the gutter would get crushed by the ladder, as if that was even a question in the first place. Worse is that you failed to answer the question in the first place. You might as well show us how intelligent you are by explaining how we have to use ladders because of gravity. If you were my student, I'd fail you for lack of reading comprehension alone.

If you look at the picture, the perpendicular ladder's outer dimensions are thinner than the long ladder's inner dimensions. It appears as if it's just leaning there on one of the rungs of the long ladder. There is no rope visibly fastened like the top and long ladder have. I don't see any hooks or ledges for it to rest on it.

In summary, you're a retard. You're welcome.

val should really just put the whole degree thing to bed

just come out and say what you have and be done with it

forget about the full sail nonsense

I've repeated it several times.

Not that it applies here as I've said nothing wrong.

The middle a-frame ladder is wider at the bottom and tapers towards the top, so it's literally wedged into the long ladder.

I thought of that too, but I it's wedged in so soon down the ladder, what are the odds.

Anyway, it doesn't really matter. It's not going anywhere.
 
Yes Val, if the center ladder was located towards the bottom of the right ladder, it would become a fulcrum and impart instability to the structure.
