i'm sorry, i have ask this before, but in different categories.I still want to collect some of your idea PMe my group need to prepare for 2 presentations about physic.I still confused about the topics for both categories.1) Electric Magnet2) Wave (sound, light, especially electromagnetic)anyone will help me out from my problem?thanks a lot!

1) Make a solenoid big enoughPut it upwardFeed it AC power (not DC)Put a small round aluminium plate over the solenoid and it will levitateYou can try a cut from an aluminium thick foil pan from the local groceryThis is the principle applied in electromagnetic (very fast) trainsThis because aluminium is a non-magnetic conductorThe currents induced in the plate by the electromagnet make the same magnetic polarity and thus the plate is repulsed from the magnet2) Diffraction of lightTake a good (low divergence) laser pointer and aim it (fastened, not with your hand) at two razor blades (The old type) holded by magnets and make the blades as close as possibleYou then put a screen (some white cardboard) in front of this assembly where you will observe the stripes of black and light called the diffraction figure(The room should be dark)Diffraction proves the wave nature of lightUse a real laser from your school for better results.
I think it might be a bit brittle and could break from metal fatigue.
Your terms of strong and durable are not specific enough to know what you really needAre you describing an application where you are using this as a spring or a structural support? Here is description home depot provides: Simpson Strong-Tie straps and plates join and reinforce joints with simple, versatile solutions for a wide range of connectionsAvailable in many lengths, widths and thicknesses, YOur temcan be used on the wide or narrow face of lumber for light repairs or heavy-duty projectsMany straps are designed to be used back-to-back on a piece of lumber without fastener interferenceA versatile, medium-duty strap for a variety of connections and splices Designed for use on the edge of 2x members, with a nailing pattern that reduces potential for splitting Install where plates or soles are cut, at wall intersections and as ridge ties 12 inLength Made from 18-Gauge steel Stainless Steel offers extra corrosion resistance for exterior and treated-wood applications Install with 10d common nails If your application sounds like what they describe you should be fineIf it doesn't you may have trouble As far as tempering your stainless I doubt you will be successfulIf you take a magnet and it is not attracted to this strap, the strap is 304 SS304SS only gains strength through work hardening (making it thinner by rolling) Heat treating doesn't affect it.
Hey Ramzi, I met this chick and was wondering if you could tell me if she would make a good wifeHere's your answer: Big Blue, there are a hundred bits of information I would need, and even then there are mysterious factors that affect the outcomeSo basically, I don't have the slightest ideaMy answer to your question is exactly the sameWithout showing exactly how the Simpson Tie is being used, there is obviously no way to know if it is suitableCan it be tempered? Sure, but again, I give it a 99% likelihood it will not help in your application Explain it in detail in 5 to 10 sentencesGive us diagrams and photosIf you can't or won't do that, here's Plan BHead over to your nearest machine shop, and ask the machinist what he thinksHe will ask the probing questions to understand the needs of the partIt is likely a Simpson Tie won't do it but he is in a good position to suggest a workable approach, and then sell it to you By the way, if this is a load-supporting member of a motorcycle or some other fast moving vehicle, be prepared to get kicked out of the machine shopThe risk of making an error is high and the outcome extremely dangerousI would not risk a million dollar lawsuit in order to sell you a $10 part.
