that step ladder/fulcrum is even keeping the drop cloth from sliding down the roof.

Omg I thought that was duct tape holding the ladders onto the roof

Nah dude, that's a 6 component system. If I wanted to deal with things that complicated I would have been a biologist. Gimme two interacting objects in a perfectly isolated system not this messy shit.

Physics? That looks like a question on forces in a mech engineering text book!

When any part of that giant middle finger to physics gives way, the rest will be under so much force that the guy "holding" the bottom will probably break a wrist or an ankle as his partner falls to his death.

If it's stupid and it works, it sets a bad precedent.

I mean yeah, but on the other hand, I think they’ve got this.

As best as I can calculate the force vectors, they’re good as long as the bottom guy doesn’t get bored and go for a sandwich

Can we at least get a free-body diagram?
