    The tension of each rope supporting the weight of the load is the same. Divide the weight of the load by the number of ropes supporting it.

    Divide the weight of the load by the number of ropes supporting it? That doesn't seem right to me. I'm looking for a quick way to identify the Ideal Mechanical Advantage (IMA) = output force / input force.
