I’ve always seen them on TV, and in professional garages and factories. I know they allow you to lift things far heavier than you normally could. But, how do they actually do that? I have seen that you pull one chain alot and it lifts it a little, so I’m sure that has something to do with it.
In: Engineering
Compounded, Newtonian directional forces. As you pull on one end of the rope, it is pulling one of the other supporting pulleys up, and that is pulling another. And as that is happening, you are providing another directional support of the “slack” in the rope that generated as a byproduct, so that one pulley is just not free climbing without providing pull on the rest of the system.
Newtonian directional forces are described in physics as, g/kg/lb/T then, N 👈👉👆👇(cant find arrow symbol on my phone keyboard)
Only thing I remember from my waste of money in college, before I jumped ship, became a free man, and decided to teach myself what I need to know for a specific project.
