weezerboy Posted February 2, 2004 Report Share Posted February 2, 2004 ello i am in the process of working my ass off for my design folder do any of you lovely wonderful genius' know how much pressure a tremelo bar has to withstand? ie. how strong does it have to be? thankies very muchies this is very very very urgent the ever grateful dan Quote Link to comment Share on other sites More sharing options...
weezerboy Posted February 2, 2004 Author Report Share Posted February 2, 2004 If no one knows, can someone please just take an educated guess....no one will know dandan the unprepared man Quote Link to comment Share on other sites More sharing options...
westhemann Posted February 2, 2004 Report Share Posted February 2, 2004 believe it or not this was asked a while back in solid body guitar and if i remember correctly was answered by daveq but i don't want to lookfor it...maybe you could pm dave q and see if my memory is correct?

westhemann Posted February 2, 2004 Report Share Posted February 2, 2004 by the way i pull up HARD on mine...and fluttering it i think puts on extra stress... Quote Link to comment Share on other sites More sharing options...
weezerboy Posted February 2, 2004 Author Report Share Posted February 2, 2004 thankyou kindly kind sir i will very quickly search my ass off, as i am trying to write critisms of my intitial ideas btw...my project was a hands free tremolo arm and no, i won;t tell you how its done dandan the slightly happier man Quote Link to comment Share on other sites More sharing options...
bowser Posted February 2, 2004 Report Share Posted February 2, 2004 if you are using a floating trem, you could use one of those tension calculators. then i believe that you would have to use some torque equations and know the length of the bar from the fulcrum. I'll try to figure it out and post it if someone else doesn't first, but don't count on a really good answer - i just got an 89 on my physics test (after a curve) Quote Link to comment Share on other sites More sharing options...
weezerboy Posted February 2, 2004 Author Report Share Posted February 2, 2004 hehe 'tis ok, really i just need a guesstimate that makes sense not like .."ummmmm two ounces" i dunno..i just need something that i can write down , as long as its roughly true thats ok these exam board fools will have no idea anyway Quote Link to comment Share on other sites More sharing options...
bowser Posted February 2, 2004 Report Share Posted February 2, 2004 well, my answer is, i have no idea. i basically thought i might be able to figure it out but instead i just flustered myself. hope someone else can help you out Quote Link to comment Share on other sites More sharing options...
weezerboy Posted February 2, 2004 Author Report Share Posted February 2, 2004 ....also its mainly for a standard strat trem thanks anyhow though Quote Link to comment Share on other sites More sharing options...
weezerboy Posted February 2, 2004 Author Report Share Posted February 2, 2004 hahaha, we don;t want no-one getting flustered if worse comes to worse i can blatantly lie my practical work speaks for itself and should knock up any marks lost from my folder work Quote Link to comment Share on other sites More sharing options...
bowser Posted February 2, 2004 Report Share Posted February 2, 2004 well i did use a calculator thing and i think that the string tension is about 89.562 with string gauges 9-11-16-24-32-42. so if the trem is set up right then this is the same amount that the springs have also.

weezerboy Posted February 2, 2004 Author Report Share Posted February 2, 2004 i made a thread a while ago on the same topic and according to the wonderful ace, that theory is wrong...can't remember why though Quote Link to comment Share on other sites More sharing options...
bowser Posted February 2, 2004 Report Share Posted February 2, 2004 oh well if its for a strat trem then i think it could be just about everything since setting it up is you preference - some people use two springs, some use 5, some use the arrow configuration, etc. and since the springs can have more force that the strings then it could be a range of different figures Quote Link to comment Share on other sites More sharing options...
Ace Posted February 4, 2004 Report Share Posted February 4, 2004 Nah what he said is exactly true, but I think it's not the answer to your question. Maybe I misunderstood your question in the original thread as well as here, but I thought you wanted to know what force is exerted on the ARM of the vibrato, so that you know how rigid your trem arm must be so that you don't bend it when going wild with the vibrato. In which case I have to say I don't know exactly off the top of my head, BUT: There is a formula to calculate the tension coefficient of a spring and using the string tension calculated with the other tool and taking that as your reference point, then measuring the stretching of the string compared to its unstretched size, you can do an equation that will tell you how much force (in Newton) you need to stretch the springs by a certain amount (depressing the bar). If that really IS what you need, I'll dig through my essential physics book and look up the formula you need. so long ace Quote Link to comment Share on other sites More sharing options...
