Thinker

my deepest apologies! I'll try to keep it on topic from now on.......

It looks like the instructor has totally lost control of his class. He's letting them get away with out wearing gaitors and the one guy doesn't have his helmet on. If he doesn't pull it together soon someone might actually smile...oh the SHAME!

I concur.

We may have a (work-related) project coming up at Cape Flattery and Tatoosh Island. Anyone know if the rock there is worth climbing? (with the appropriate permissions, of course, from the tribe)

between a pack and a hard place.

sure has been a long time since I've seen any good 111's.

I didn't know Jim sold those

Myo3 rules!

Cool...I'd go with you if I didn't have Salsa dance lessons on Thursday eves.

Have you seen the ads for the people who make door mats from old climbing ropes? IMHO there's just something fundamentally wrong with wiping my feet on my favorite old ropes. Sacrilige! What kind of cool things have you seen done with old ropes?

wasn't the "RSVP by" date the 7th or 9th?

Touching the

When I composed this question I had to count down over 20 posts to find one that Trask had started. Has the intellectual diarrhea about mars, orbits, and dehydration scared him off?

Matt, are you talking about those fern bars again? I knew there was something suspect about those innocuous looking places.

ban the

very geeky cool!

so why does Alpinfox's original post say "edited by ChucK"? are both of the #2 keys on your keyboard inoperative?

I can see how it could contribute to hypothermia, but dehydration doesn't make sense to me.

It's good to see more of the details coming out. the articl states "One time, Witkowski said, he was so tired, he just laid down next to a creek, so he could lean over into the water and drink. He didn't eat snow because he knew it would dehydrate him." Someone please learn me a little bit. how can eating snow dehydrate you?

I'll take a stab at this off the top of my head. NO. rpm equates to angular velocity, not the 'straight line' velocity of an object in orbit. The centripital force actually creates an acceleration of the body, i.e. it changes the direction of the body. For instance, if the ball being swung in a circle on a string were to have it's string cut, the ball would tend to travel in a straight line (given no earth gravity effects). Thus, the string is changing the direction (accelerating the body) constantly. The tension in the string is equivalent to the force changing the direction, which is the centripital force. Given a higher RPM, there's also a higher 'straight line' velocity that has to be overcome by the tension in the string. In other words, f=ma, and a higher rpm requires a greater force to maintain the equivalent centripital acceleration.

There is no outward acting force. The force of a simple orbiting body has 1 component if it is orbiting at a constant velocity. That force is the centripital force, directed toward the center of the orbit. If a force is applied the body will accelerate in the direction of the force, whether that's toward or away from the center of the orbit. A force can act to accelerate the body, and in that case the body can (but not always) escape the orbit. If there were a constant force acting outward (180 degrees away from the direction of the centripital force), the body would accelerate away from the center of the orbit and likely jump orbit.

I can't think of a better place for G-Dub. Can we get this program sped up a bit? I'd push for a launch date early this year!
