 ```...without 'sticktion' we wouldn't have the wonderful sounds of all the bowed instruments in a string orchestra. And without the 'sticktion' effect, we wouldn't have to whack those old finicky gadgets to get them to start! Ever bring an old hard drive back to life with a coupla good whacks? They still work! We, umm..... at work still emply this technique for troubleshooting. We get away with it by calling it "the Technical Tap." About calculus - join the club! I've forgotten most of mine, too. --...MARK_N1LO...-- >In the long and useful thread about mast clamps that slip under torque, >several contributors have discussed the friction between the clamps and the >mast.
