Weight increase on a lever as distance from body increases

    1. The problem statement, all variables and given/known data

    very 'uninformed' person here please bear with me. this relates to a piece of work equipment that i use but am not comfortable doing so.
    a 6" aluminum rod that weighs 6# is extended from its vertical away from the body to reach a 'target' from 4' to 6' away. the rod will at theses distances be held (with one hand as the fulcrum) at a distance of about 2' from the end closest to the body.

    2. Relevant equations
    the force exerted in a downward direction will increase but by how much? in otherwords; if the rod weighs 6# at rest vertically how much force is applied (in #'s) at its extreme end when extended from the body a distance of 4 ' & 6' at a 45 degree angle.

    3. The attempt at a solution
    my only attemt to solve when using this at work is to notice the extra strain in my lower back and shoulders and to stop using it. i need a safer way. i would prefer a direct response to my e-mail due to work hours :srthomsen1@verizon.net. thanks
