    shared weight limits help

    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.

    Ans is 1 person= 100lbs
    the calculation is average weight method.

    one person can lift 100lbs and other can lift 100lbs
    Then average of two people lift is 100lbs.

    Got stuck with Average Weight problems ?

    To me, this is a physics question, not a mathematics question...Am I correct in my assumption?

    Anyways. I'm going to use KG instead of LBS.

    A person can lift 100KG. That means that he uses the force: F=ma.

    m = 100kg, a=9,8m/s^2 (gravity) and we get 980 N.

    If two people can lift 100 kg each, then their combined lifting limit would be 980*2=m*9,8m/s^2=200kg.

    I'm not sure if this is what you are asking...But I'll leave it here in case.
