 Title: Physical Quatities and Units Post by: sakuralim on July 04, 2005, 09:04:11 pm Hi everyone ^^  :D I am very weak at physics, so I hope that someone may help me with these questions1.  The frequency f of the note produce by a streched string depends on its length l the tension T of the string and the mass per unit lenght m of the string. Use the method of dimension to derive an equation for f. Title: topic221 Post by: Fu-Kwun Hwang on July 05, 2005, 09:19:30 am Because the question assume frequency f depends on  tension T, length L and mass per unit lemgth mAssume the relation is f= TaLbmcThe dimsnsion must be the same on either side of the equationDimension for f is 1/tDimenswion for T is M L /t2, dimension for m is M/L  1/t = (M L /t2)a Lb M/Lc=Ma+cLa+bt-2aso -2a=-1 , a+c=0 and a+b=0 Title: thanks ^^ Post by: sakuralim on July 05, 2005, 09:21:23 pm thank you HWANG for helping me out.Now I can understand a little bit. ^^ Title: topic221 Post by: johnza on August 27, 2005, 01:15:00 pm i am teacher of physics thanks Title: Re: Physical Quatities and Units Post by: Edward Collin on December 08, 2010, 10:59:20 am I am also a physics student upto high school, but have never been able to catch these solution. Now I wish to do Bachelor in science, this is somehow helpful for me.
