Has anyone seen my shoe? Posted January 19, 2007 Report Share Posted January 19, 2007 Basically im doing a presentation on the above, so I to know reasons why manufacturers choose al over steel for example.I dont mean, its lighter then steel, cheap then titanium. I mean physics-y stuff like youngs modulus, stress, strain etc Quote Link to comment Share on other sites More sharing options...
Walleee Posted January 19, 2007 Report Share Posted January 19, 2007 (edited) Matweb.comI also have a few books which could help you on this one;Bicycling science 2nd ed - Frank roland Whitt & David Gordon WilsonBicycle Design - Mike BurrowsHigh Tech cycling 2nd ed - Edmund R. Burke.Some really good materials comparisons and stuff.here's an example of what criteria you'd be looking for"The density of the material must be such that the resulting structure is light.The resulting structure should not be unduly flexibleThe failure should be gradual rather than sudden (down fall of aluminium, snaps rather than bending like steel)The cost must be reasonableJoining one piece to another should be possible without loss of strength in the parent material of the jointThe material should intrinsically resist or should be easily protecte from, corrosion."At the risk of doing your assignment for you, here is something you should find very usefulSteel AISI 4130 CrMoYoung's Modulus 200GPaUltimate Tensile Strength 1,425 MPaElongation at failure (%) 12Density Mg/m3 7.85Aluminium6061 T6 Young's Modulus 68.9GPaUltimate Tensile Strength 310MPaElongation at failure (%) 12Density Mg/m3 2.87075 - T6Young's Modulus 71.7GPaUltimate Tensile Strength 570 MPaElongation at failure (%) 11Density Mg/m3 2.8 Edited January 20, 2007 by jake1516 Quote Link to comment Share on other sites More sharing options...
future orange 660 Posted January 20, 2007 Report Share Posted January 20, 2007 i think the ultimate tensile strength of steel may have the decimal in the wrong place Quote Link to comment Share on other sites More sharing options...
Walleee Posted January 20, 2007 Report Share Posted January 20, 2007 whoops, it should have been a comma rather than a point! sorted now! Quote Link to comment Share on other sites More sharing options...
IOLO Posted January 20, 2007 Report Share Posted January 20, 2007 I also have a few books which could help you on this one;Bicycling science 2nd ed - Frank roland Whitt & David Gordon WilsonBicycle Design - Mike Burrowsace i have those books they are gd,iv got a couple of bike books that are REALLY thick and geek tastic too !!and just out of interest, u seen the 8 foot wheelbase freight bike in the Burrows book??last page of the colour pictures in the middle,i just ordered one ! well excited. (will be making my own at some point, but aint go the time right now)and erm ye, ALU rocks !! (steels better, mans metal ! ) loliolo.

Has anyone seen my shoe? Posted January 20, 2007 Author Report Share Posted January 20, 2007 Thanks for your help, its a physics presentation im doing in which I have to investigate a material and its use for a certain purpose.I was going to do fibre optics and their use in telecomunications Quote Link to comment Share on other sites More sharing options...
