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

Click For Summary

Homework Help Overview

The discussion revolves around the mechanics of bow and arrow systems, specifically examining how string length may influence the force exerted on an arrow. Participants explore the relationship between string tension, elasticity, and bow design.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants question the relationship between string length and force, with some suggesting that elasticity plays a role. Others inquire about the implications of different materials used in bow construction.

Discussion Status

The discussion is active, with various perspectives being shared. Some participants are exploring the mechanics of tension and elasticity, while others are considering the effects of bow design on performance. No consensus has been reached, but multiple angles are being examined.

Contextual Notes

Participants are navigating assumptions about the physics of tension and elasticity, particularly in relation to different types of bows and materials. There is an acknowledgment of varying interpretations regarding how these factors contribute to force exertion.

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
