Alright n00bs, you had two weeks since I posted my 3:1 MA, and now quiz time.
To review 3:1 click link

Three questions;
What type of MA we got here
A- simple MA
B- Complex MA
What is the MA on both system combined ?
A- 4:1
B- 8:1
C- complex 3:1
D- 7:1
E- 5:1
Assuming all ropes are in straight line. if tire weights 300 lbs, how much weight Joe is pulling +_.
