Walter & Group....
Fish story: Yesterday morning, I hooked a small tarpon. A shark cut him in half. I put on a Lefty Kreh shark fly and wire bite tippet and jumped a spinner shark which cut through the wire (They almost always get off by biting right through the wire or twisting off the leader as they jump and spin around......They can jump 15' or higher as they do the, "twist". Rare, indeed to actually land one.)
Rigged up again with my last shark fly.... hooked and caught a small spinner shark ( about 25 lbs.). After releasing the critter, three other larger sharks tore him to bits.
I went home for breakfast. G.
Predicted path of Ike is way too close for comfort.
We've "Battened down the hatches" , secured the skiffs and are evacuating. G.
One last Group message From Walter Simberski :-
Gordy,
I think this is great stuff from all sides! Guy has provided
some great
analysis irregardless of how he understood the original
question.
As you and Bruce noted - there is very little linear motion
that occurs in nature. I like to think of the how a locomotive works - the drive
wheels turn, which drives an arm that drives a smaller set of wheels that in
turn provide linear motion along a set of tracks. Rotation drives rotation which
in turn is converted to linear motion. In order to generate pure linear motion,
i.e. translation, engineers have come up with something called a linear actuator
but this is a specialty device that is used for specialty applications and I
don't know of too many things (other than falling down a rat hole) that are
alike. Most of the time we are quite happy to make use of rotation to create
linear motion.
I can't tell you how happy I am to see how much thought
people are putting into
this!
Thanks
Walter
