Question

Real life math problem. I'm going to describe what I experienced and I want help designing a series of equations to satisfy my curiosity. Anybody interested?

Answer 1

I was doing lat pull downs at the gym. The machine had 1 pulley and 100. I moved to another lat pull down machine with 2 pulleys attached to the weights and at the same 100 mark I could not do it. I want to find out if two pulleys creates double the resistance

Answer 2

For the sake of filling in the unknowns lets say the bar is negligible and each pulley has the same amount of friction and wire tension

Answer 3

What is it attached to?
