Alright, if you're going to give me an answer about how unethical it is to shoplift and whatnot - don'tI won't listen and I'll delete your answer.I know that if you're shoplifting something with a security tag on it, you can put the given item in an aluminum foil bag (known as a quot;magic bagquot;) and when you walk through the door, the alarms won't ringI don't have time to make a bag and I was wondering what would happen if I went in, took items into the dressing room, wrapped them in aluminum foil, and put them in my bagWould this still work?Thanks.
If they don't hear the rustling of the foil in the changing room I would be real surprisedThat stuff is loud.
How fast is the rotation speed? The problem is, aluminum is too softProbably the best thing would be molybdenum greaseYou asked this in the aircraft category by the wayI mean, I know a fuselage is a tube and all, but.
There are a number of critical bits of information left out, such as How fast must this bar be able to slide and how much driving force will be applied? Will the bar need to support any weight radially? One off-the-shelf solution would be to use a linear guide rod - they're precise, able to use recirculating ball bearings and they're strong (usually made of high grade steel).
