Relationship Between String Tension and Stretch

AI Thread Summary
Stretch in a string affects the relationship between wavelength and tension, with the expectation that a stretched string will have a lower slope on the wavelength vs. tension graph compared to an unstretched string. The tension in the string can be modeled using Hooke's law, T=kx, where T is tension, k is the spring constant, and x is the stretch. The experiment involves attaching the string to a speaker vibrating at 60Hz and adjusting the tension by hanging a mass, aiming for even oscillations. Accurate measurement of wavelength is crucial, as it directly relates to the tension applied. Understanding these dynamics is essential for analyzing the effects of stretch on string behavior.

Homework Statement


Will stretch in a string have an effect on the graph of wavelength vs. tension, relative to the same graph using a string without stretch?


Homework Equations


N/A


The Attempt at a Solution


No calculations are required, so I'm assuming that the slope of that graph in the string that stretches will be lower than the slope of the graph based on the string that doesn't stretch. This is all the information I really need to get the rest of the answer to the question.

tl;dr: Does stretch in a string affect its tension in a negative or positive way?

Thanks!

Well tension in a spring can be modeled as a spring such that T=kx. But what exactly is the 'wavelength' that you are measuring?

That would probably be some useful information, wouldn't it? :P

We're attaching the string to a speaker and vibrating it at 60Hz. Then we're hanging a mass on the string over the edge of a table, and moving the speaker until we get a tension that creates even oscillations.

We then calculate the wavelength from measuring the string directly.
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
