1. The problem statement, all variables and given/known data I did an experiment about the loading of tuning forks. I added blue tac to one of the prongs on a tuning fork and then weighed it. I then measured the different frequencies for each mass and plotted a graph which ended up looking like a exponential decay graph. The results are shown below : Mass(kg): Frequency(Hz): 0.05179 307.83 0.05219 305 0.05269 302.83 0.05335 301.17 0.05378 299.83 0.05572 299.17 2. Relevant equations ω = 2πf ω = √(k/m) 3. The attempt at a solution When a tuning fork oscillates it is under SHM as when the prongs oscillate there is a restoring force towards the equilibrium. Using the equations of SHM, I did : 2πf = √(k/m) ∴ f = √(k/m) x 1/2π. As, k and π are constants, we can rearrange the equation so that f = √k/2π x √1/m. So if I plot f on the y-axis, and √1/m on the x-axis, I should get a straight line with √k/2π, being the gradient. However, I still get a exponential decay looking curve when I try to do that! I've then gone on to try the usual logging both sides and then plotting a graph of lg(frequency) and lg(mass) but I still get a curve which is extremely strange? I tried plotting frequency to (1/mass)². But still I get a curve? Could anybody please point out where I have gone wrong or done something careless? I can't seem to spot the problem and can't linearise the curve!! Thank you so much in advance, your help and advice is greatly appreciated!
