--- Quote from: ruby92 on April 20, 2010, 07:32:10 pm ---the ultimate tensile stress is a point before the fracture/breaking point.where the materia "gives" or "yields'??
is this right?

nope..only the first part is right..UTS is NOT the yield point..the yield point is the point where plastic deformation starts...UTS is simply the stress where the material breaks..

what wld a displacement position graph for a longitudnal wave look like?
if anyone has notes on superposition and resonance particularly explaining the wavelenght and lenght if you could post it here it wld be realli helpful :)

Graph is an exact duplicate of the one for transverse wave
Notes: http://www.s-cool.co.uk/alevel/physics.html go to oscillations and waves part

@A.F ; it doesn't have much on resonance ???
