Tension problem

    According to the equations, the tension of a string depends only on the the force acting (pulling) on it, and not on the length of the string. So why can someone with a bow and arrow with a long string (long bow) exert more force on an arrow than a bow with a short string (short bow)?
    Does it have to do with the angle of the string?
    Thanks!

    I think a bow and arrow has to do with the elasticity of the wood. The longer string allows for a longer piece of wood which can be bent further, giving more force.

    But isn't this true also for a metal bow that dosn't bend?

    ok the truth is the the tighter you have the bow string and more poundage you have there for the more force the bow can exert on the arrow
