What are the best tips for building a spaghetti bridge for a physics class?

Triangles are the strongest shape and don't boil the spaghetti.

Thats sounds like a good idea as you will def need physics at a very good level to do engineering!...;

Sorry I'm the kind of teacher you parents despair of because thats the kind of home work I'd set.  My class have to design and make a thermal insulator to stop ice melting this week!!!\n\nTry this link it might help\nhttp://www.volcanolive.com/model.html

1) use conservation of energy:\n\n1/2*m*vb^2=1/2*m*va^2+m*g*h\n\nm=2\nva=4\ng=9.8\nh=6\nv=sqrt(16+2*9.8*6)\n=11.56 m/s\n\n2.\nSame concept\nm*g*(bounce)=1/2*m*va^2+m*g*(drop)\nmass divides out\nbounce=va^2/(2*g)+drop\nva=6\ng=9.8\ndrop=4\nbounce=36/(2*9.8) + 4\n=5.84 m\n\n3)  since the mass isn't moving it's offset the 300N force\n\n4)\nAgain, use conservation of energy\nNote that the change in potential energy will subtract from the kinetic energy of the start \n\n1/2*m*vc^2=1/2*m*va^2-m*g*delta-h\nthe mass divides out\nva=8\ndelta-h=2\ng=9.8\nvc=sqrt(64-2*9.8*2)\n=4.98\n\nj

My science class did the same project a few years ago. I suggest suspending the egg within a sphere, try making wings to slow its fall. I dont think whether it is a trianlge or not will really affect its streght to much. Good luck

Do demonstrations! For volume, for example, you can show a cone has a third the volume of a cylinder with the same radius by pouring water from a cone to the cylinder. Most students guess that the volumes are about the same and it's a demonstration that sticks in their minds. \n\nAnything outside of the classroom is great (if you can do that). Interactive stuff is always good. Get them to estimate the area of the basketball court or other playing surface. Or figure out how many people you could fill your classroom with if they were all lined up lying down.

You will need the following materials: \n\n• balloons \n• long wooden or metal skewers \n• petroleum jelly \n• a sharp pin \n• cellophane tape \n\nBlow up a balloon – not too full – and tie the opening shut. Dip the tip of a skewer in Vaseline and spread the Vaseline along the entire length of the skewer. If you are careful, you should be able to push the skewer all the way through the balloon without popping it. Insert the skewer with a gentle twisting motion into the end of the balloon opposite the knot. Continue pushing and twisting the skewer until the tip emerges from the other end, near the knot. Why doesn't the balloon pop? \n\nNow try to stick the skewer into the side of the balloon.What happens?\n\nThe rubber in the balloon consists of many long molecules that are linked together. It's similar to the way all of the noodles in a plate of spaghetti stick together. These long molecules are called polymers; when molecules of a polymer are chemically attached to each other, it is called cross-linking. These links hold the polymer molecules together and allow them to stretch…up to a point. When the force or tension pulling on the cross-links is too great, they will break, and the polymer will pull apart. \n\nLook at the rubber near the ends of the balloon where you first inserted the skewer. Does it look lighter or darker than the rubber in the rest of the balloon? \n\nThe rubber at the ends of the balloon is stretched out less than in the middle of the balloon. Therefore, there is less force pulling on it. This allows the tip of the skewer to break some polymer cross-links, push aside the molecules of rubber, and slide into the balloon. However, enough cross-links remain so that the balloon holds together.\n\n\nIn the side of the balloon, there are fewer polymer molecules. When you push the tip of the skewer through the rubber in the side of the balloon and the skewer breaks a few of the cross-links, the tension on the remaining cross-links is too great, and the balloon pops. \n\nDo you think there is a way to stick a sharp pin through the side of a balloon without popping it? \n\nPut a small piece of cellophane tape on the side of the balloon and press it down well. Now take the pin and press it through the tape and into the balloon. Does the balloon pop? \n\nThe tape sticks to the rubber in the balloon and will not allow the rubber to stretch to the breaking point when the pin pierces the balloon. In other words, the tape reinforces the cross links, and the balloon stays together.

Sorry, but with the time you spent typing these questions you could of looked them up in your physics book or googled them.  Sometimes getting others to do your leg work isn't always the best answer to a problem.  Good Luck in your new class!

jeez - that sounds a demanding course.\nmake a paper boat in the style of an old galleon and stick a coin in the bottom. It will stop it falling over and demonstrate how the galleon can transport gold without sinking.\nThat should give you an E instead of F.

One of my favorites was making a tornado in a 2 L soda bottle.\n\nWhat you do is take a bottle and pour it almost full of water. Get some grass and some small toys, like cars to put in there. I like to use the monopoly houses to. Then put a small drop of soap in then swirl the top a the bottle around really fast. There ya go a tornado. Then give a one or two paragraph summery on how a tornado is formed.

Well i am taking physics class this semester and we have to use websit to do our home work so please go to\n\n\nwww.masteringphyiscs.com\n\nyou will find all the topic for physics 1, 2 and 3...\nif you need help to search for the any topics than contact me...

Take some balloons and blow them up and watch them slowly lose the air in side over a few days.  Then explain what Osmosis is.   : )   While you have the balloons out fill some with helium and show the kids how they can make their voices change.  Have your video camera ready this will be a hoot!!!

Look up Vector Mechanics for Engineers and Scientists.  This deals with basic Newtonian physics as applied to static structures.\n\nBone up on chemistry.  It is easy to forget your chemistry, and as far as I know you will be required to take a few semesters of basic Chem, even if you are not planning on being a Chem Eng.\n\nDo not lose your Maths either!  Grab a pre-calc or a calculus book and keep practicing.

1. Build a really big sail\n2. Magnets (think of the magnetic trains that Japan uses, however the whole roadway would have to be made with magnets to pull this off)\n3. Using Pascal's principal of compressed liquids you can probably make a peddle system (Brakes and most powered steering systems use Pascal's principal, source 1)

Try buying a copy, try a local structural design firm, try a local engineering school, try a local library.\n\nIf you know enough to use the load factors, you should know enough to find them.
