Wakeskate Equation

Frye · Guest Joined: 14 Sep 2003 Posts: 3335

So my physics teacher told us we had to write an essay, so I started the first few pages about wakeskates, like how the way the board is made affects the way the water flows, and the pop, and all that other stuff. But as I was finishing up he said we need an equation in the paper. So does anyone know an equation that has to do with wakeskating that I can use and like some variables that i could plug into it to demonstrate? Like mebbe with the bi-level pop or something I don't know you guys do your thing. Thanks

Force of gravity.....arrow down
force of kinetics.....arrow right or left

Just copy some crazy fluid dynamics formula. There are many of em, and they would all pretty much have to do with wakeskating in some way. google it or something... Get a basic understanding of wtf it is so when she asks you can give a little explanation. If she's a high school teacher she'll have absolutely no idea what it is anyway, so you can BS your explanation a lil bit.

and bjr, I don't think just showing direction vectors for the forces would really count as an "equation"

frye, ur not smart enough... sorry
call me.

just do somethin with the rocker and the concave = .... pop or somethin like that

just make some shiaat up

leveage of the tail and speed of the board on the water to get pop?

i think its called folcrom point, which is the exact point that cuases the board to pop out of the water?

i dont fizzle no

you could do something with the force that you push down with to pop and how high up that gives you. the higher the force, the more pop you get.

just do sometrhin with water density, about how in saltwater and frshwater its a diffrent ride. Or about how much surface are and what not.

Or like on the bilevel the fulcrum effect.

Guys all great ideas, but he needs a formula!!!!

Giving theories may not help that much.

Take a look at Bournoulli's equation, it might work for what your asking. Nice and simple too

in a old wakeboarding mag the was a big article about the physics of wakeboarding and wakeskating so if u got old wakeboarding mags look through em

You could talk about the force of friction on the board. Find the coefficiant of friction for water, calculate in the speed and then find the total resistance for the board.

Fr = (Ff)(V)

Or you can calculate the force of tension on the rope.

Ft = (Mass)(Velocity)(Friction)

That's probably not the exact forumula...if I had my physics notes at home I could look it up, but I don't so...yeah, just try google.

I think your best bet would be finding the force of tension on the rope.
