Long vs Short Bows: Does Force Depend on String Length?

Click For Summary
SUMMARY

The discussion centers on the relationship between string length and force exerted by long bows versus short bows. It concludes that the tension of a bowstring is influenced by the elasticity of the material, with longer bows allowing for greater bending of the wood, thus generating more force. Additionally, the tension in the bowstring, determined by its tightness and poundage, plays a crucial role in the force exerted on the arrow. This indicates that both the length of the string and the material properties significantly affect bow performance.

PREREQUISITES

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
