Some considerations on casting and rod loading.

A simple calculation for casting in air is;

Frt = Fi * Fa * Ff * Flt

Where Frt = the force on the rod tip in kg.m/s², Fi = inertia (mass)
in grams, Ff = the coefficient of fluid kinetic friction µk ( air
resistance), Fa = the acceleration of the line in ms², and Flt = line
tension in kg.m/s²


You might want to check your units, Mike. I get Frt would be in
Kg*g*m^2

If you mean acceleration of the line is in m/s^2, then the units of
Frt would be even worse: Kg*g*m^2/s^4


I think you need another factor in there...but Physics isn't my strong
suit.
