A2 CIE PHYSICS (9702) - PAPER 5 - DESIGN QUESTION
joel:
Could anyone do the October/November 2002, Paper 5, Question 2.

Thanks!
joel:
All the design questions from May/June 2002 to October/November 2006 are really tricky.
So I you guys don't mind, can you upload your answers if you have done those questions.
I am also attaching a pdf document containing all the design questions from June 2002 to November 2006.
Please reply soon!

Just a heads up... people may take a while to reply.. because if theyre like me- they havent done the papers before 2006. :-\
But I'll have a go anyways :D. In simple.. for the experiment I'd probably have a signal generator attached to a vibrator connected to the string. The string would be in a pulley system with a known wieght attached to the end (can find tension from that). For different masses (tensions), vary the vibrations until a max amplitude is seen.. the frequency that it occurs at is the resonant frequency. Record the resonant frequency and tension.. construct a graph- tension on x-axis and frequency on y-axis. right? And the controls- same mass per unit length of wire.. same length of wire (basically same wired used) for each tension... but the thing im stuck on is -would you have to change the lengths to keep it at the fundamental mode for each tension?? TBH- i cant remember what the fundamental node is. :P and safety - i dont know?- maybe ear protection incase of high pitch frequencies?
hope i helped in some way. sorry if its vague.. its just off the top of my head.

how can u find the tension from the weights?

dont know.. google it. :P
Im pretty sure its got something to do with the weight. ?
