    People in corporate america may appreciate this.

    lmao well, I'd figure at most dropzones they'd at least keep track of your numbers, and if you've been filling out your a-license proficiency card as you go along (you have haven't you?) you can just pick up a beefier log book and start on jump #whatever and do a memorial jump for all the comments you lost

    speaking of jobs, looks like I might very well be joining you down in Plantation starting in May, I just got an offer to work at Motorola (Sunrise Blvd and University Dr) If I do decide to work there I'll definitely be hitting up SoBe

    jumped a 182 a few weeks ago after not having since I was a student. Definitely felt funny doing a 4-way from where I used to do hop and pops

    like Dytters and slinks and Jump-Track links, it's the greatest gear store there is! I don't want to grow up, cause if I did, I couldn't be a Drop Shop kid.

    singing... Ohhhhhhhhhh..... If you want possessive, it's just I-T-S... but if it's supposed to be a contraction, it's I-T-APOSTROPHE-S... Scalawag.

    You're truely a skydiver after you've bought beer. There's definitely something to be said for learning humility. For those who argue, "eh, jump out of an airplane and you're a skydiver.." I ask you this, how would you feel about someone doing a tandem, and then buying a closing pin necklace, wearing it all the time, but never going back to the dropzone?

    as a university club pres I make it a point to encourage people to keep up their progress as students, whether they're making a couple jumps every couple weeks, or they go all out and get their license in a month. I'm no veteran as I've only got about 14mos in the sport, but I know I'm going to get looked up to along with the instructors at the dropzone. I love listening to people's excited accounts of the jumps they did that day, it reminds me of how crazy it was being on student status. We bring a number of tandems out too, and I try and urge them to consider doing the license thing. A few have, but most tell me they had fun but don't see themselves doing it all the time. But I figure hey, they came out and jumped with us, that's all I can really ask of anyone.

    hey man nice work, you look like you're ready to downsize... Well, I can't say I've ever flown a Spectre, I'll just assume they're really hard to land.

    If you want to carry the problem into a rotating reference frame, that's fine. In such a frame you will get a pretty simple static setup with two objects pulling in opposite directions on each other. However in this situation, I don't feel we gain anything by setting it up like this. The description of what is happening to the jumper/parachute before the spin is started, and after a cutaway takes place becomes hopelessly mired when trying to use a rotating frame of reference. I could create a frame of reference that was travelling east at 1+cos(10t) and there'd be all kinds of forces acting on the spinning jumper, it doesn't mean it's necessarily useful to discuss them. From a stationary point of reference, the description of the system before, during, and after the spin is incredibly simple.

    This is clearly out of hand.

    bleh, it's all about learning the material, not getting a grade. I did terrible on the tests in the calc III class I had to take (way back when) because I sucked at memorizing all the lousy properties. I'd get the solution down to an integral I couldn't solve, but my grade still got reemed. All the courses I've taken that rely on calculus don't care if you remember all the details, most of the time they're even given to you, you just have to be familiar with what's going on.

    I thought the picture I drew and attatched to the original post made it pretty clear...

    The centripetal force to keep you spinning is provided by the lift of your improperly oriented canopy. The equal and opposite force is on the air molecules passing over the lower surface of the wing. (Bernoulli's Principle)

    I added it to my other post because I noticed it in that quote taken from wherever, but I'll emphasize it because it is just so huge. Forces do not move things. Forces accelerate things. If you are driving your car going 60mph (forwards), and slam on your brakes, you are applying a huge force on your car in the backwards direction, yet you will not move backwards. At any given moment in the spinning example you are travelling tangent to the circle. Inertia doesn't know or care that you are spinning. All it wants to do is keep you moving in that straight line. A constant force towards the center of the circle keeps changing your direction and makes you move in a circle. If the force is taken away (you chop) you will continue moving in a straight line, tangent to the circle.

    As I said, this is more semantic than anything. If you look at you in your harness, there's only one force applied, and that's towards the center of rotation, this unopposed force causes you to accelerate towards the center of the rotation, and makes you spin. If you want to argue that your harness is pushing on you, and you are pushing back on your harness (to prevent from moving relative to it), that's fine, but that force has nothing to do with rotation, that interaction takes place completely within the box in my drawing. /edited to add: "A centrifugal force is a force on an object that tends to move it away-" No no no, bad bad bad, wrong wrong wrong. Forces DO NOT move things, forces accelerate things. And yes, there is a big difference.

    Keely, if he buys one, can I get commission?

    Ahh crap! Hmm, would you believe me if I told you I use a strange keyboard where "o" and "a" are adjacent and my finger slipped? And there's nothing wrong with a little flair in your flare, as long as you don't break a brake.
  23. champu
    I am well aware that the sole reason this thread exists, is because I am a colossal nerd... what I was really getting at is that the acceleration you experience, or in other words the Gs you undergo are "centripetal" or directed towards the center of the rotation, and that's why you feel heavy in your harness. You'll have plenty of time to ponder the finer points of what just happened while you wonder around looking for your freebag
  24. champu
    YES! with the flashlights, and the ropes, and the mice in the wheels, and the baseballs, and oh it just goes on forever...
