Hi,

I would like to propose a hypothtical to get some answers to help me understand speargun dynamics. Please humor me

1. Suppose we have four identical long spearguns with identical spears with wishbone slots all along their length so that band stretch can be easily varied.

2. Suppose we put one fat short band on one and and stretch the band to put one hundred pounds of force on the spear.

3. Suppose we put one fat long band on another and stretch the band to put one hundred pounds of force on the spear.

4. Suppose we put one thin long band on another and stretch the band to put one hundred pounds of force on the spear.

5. Suppose we put one thin short band on another and stretch the band to put one hundred pounds of force on the spear.

6. Then suppose we fire them all and measure what happens to spear travel.

Will there be any differences given that the spears are identical and the initial applied force is the same?

What factors and effects should be considered when desigining a speargun in regards to the diameter and length of the rubber?

Thanks
