Ok, I don't know if I'm in the right section or not but here goes my question.
What is the calc for this. Say I have 1 person who can lift 100lbs. His limit is of ccourse 100lbs. But if I have 2 people who can lift 100lbs what is their combined lifting limit. Add a third person. I know there is a spesific calc for this but I can't remember it.
