Strange question of physics in casting

[Angrybear]

Prompted by a joke on a shooting forum, has anyone ever worked out the physics of a cast ?
As an example if the world record is 313m with 125g (339yds - 4oz) what sort of velocity & initial energy did that lead have ??
Google has failed me as have my shooting ballistic programs so I wondered if someone in the casting world had worked it out ?
the shore section seemed the place to ask.

I imagine the cast would need some basic physics ingredients?

• 45 degree initial trajectory (maths - max distance)
• ultra light main line (less drag)
• aerodynamic lead on a swivel (allow it spin for improved stability)

 

[Angrybear]

Maybe, but if you have the weight - distance & flight time you can get started on the energy & velocity.
I'm stuck because I don't know the time the lead was in flight.

That's interesting. You could look at some of the championship casts on YouTube to obtain a flight time.

I can tell you (personal experience, and also bloody obvious) that a short rod will not allow the same distance as a long rod - also a stiff (cheap) beach caster is less efficient than a through-action.

Will also depend on wether you are right or left handed.

And if you have a following wind.

Use your ballistics program. Newtonian physics is universal. You'd have to factor in additional drag and the inertia the line causes

distance unit measured bias + angle slope squared / quantitive unit equation sum + time in order numeration

Sounds like concrete.

how would you calculate the drag.... it's not a linear calculation.... the rest I am sure is quite Googleable but the variable drag I have not a clue.
I suspect you may be able to make some assumptions working backwards.
