Part 3?

Hello, I have a question and suggestion to part 3: As You mention in previous part, MA of the system is equal to number of strings attached to the load. There is a competing opinion that MA of the system is equal to number of pulleys attached to the load multiplyed 2, so it can only be even number: 2:1,4:1, etc.., so odd MA systems are not exists and last odd string attached to load directly is have only load re-directional role. Can You please make experiment of simple pulley system with 5:1 and compare it with equal 5:1, but attach last 5th string not to the load, but, let's say, to the ground, or some another static point and compare effort required to hold load hanging under the ground. I have made attempt to do such experiment, but i haven't digital measurement equipment and because of friction and small weights i've used I was unable to achieve solid result proving one or another opinion.

Hello, Very hard to handerstand and to reproduc, but it's working (one goes x2 speed than an others). Thanks i'll watch the other time to assimilate! Sorry for the orthograph.
