No, the other commenters are right — it’s between 100 and 150 depending on the angle. And it’s like this because we have 50 N + 50 N on both sides of the top pulley (classic pulley thing) + 50 N more attached to it at the bottom. Kinda confusing at first, not gonna lie :)

Okay, I’ve found a nice picture for it. Whoever sad 150 N (with the 180° angle, less with other angles) was right, and the rest of us were wrong :)

The problem with regulators is that they a) gladly suck corporate dicks, b) gladly opt-in for the same authoritarian methods of population control, and c) gladly ignore common sense altogether.

It should be 50 N assuming ideal system (0 pulley traction), right? What about non-ideal systems?

What’s the force in this point?
