whatup guys, i gatta do a physics project on anything we want so i decided to do it on how suspension works on quads... i gatta include liek how their made and with what materials, and how exactly they work.. anyone no of any sites that can give me info on this topic? i gatta write a 5 page paper so i need all the help i can get.. thanks in advance fellas

 

Couple of ideas for you:

1. Take one of your quads down to the metal and look at its construction, action, and materials.
2. Go to a dealer (explain what you are up to) and see if they have a junk frame or junk parts to use as demo material.
3. Get some parts and exploded drawings from the internet and study how they work.

and for the big one...

4. Get some Lego technic parts and build several working models to show leverage, travel, damping, and rebound. Use some graphs and charts to show some math and physical action models. You can buy Lego technic parts (beams, pins/pivots, axles, etc.) for cheap on the internet at http://shop.lego.com/

Be sure to use terms like: compression, hydraulics, leverage, linkages, bearings, lubrication, springs, unsprung weight, potential and kinetic energy, equal and opposite reactions, etc. when you write your paper explaining how everything works.

 

ok, thanks alot for your help man

 

Go to Yahoo and search for "how things work"..then maybe subscript "suspension".

 

Also don't forget to mention how shocks will sometimes "load Up' when put under constant, repeated compressions and how a shock will be less useful as the oil in it heats up, thereby becoming thinner and passing through the valving mechanisms at a faster rate. Springs will also heat up under constant, heavy use and will not have as much tensil strength.
Many variables to think about and explain. Very easy to get a five page paper on this subject. Could be double that easy.
