Amplitude of string when the string breaks

In summary, the conversation discusses the impact of removing a mass from an oscillating system on the period and amplitude of the oscillations. The group agrees that the period will be shorter due to the smaller mass, but there is disagreement on the effect on the amplitude. One person argues that the amplitude will be greater due to the new equilibrium position being further away from the original, while another argues that it will be smaller due to the displacement being less. The conversation ends without a consensus on the effect on the amplitude.

Homework Statement



my question is on part b

Homework Equations





The Attempt at a Solution



the period will be shorter due to smaller mass of oscillating system... but the amplitude is greater( ans from my book , in my opinion, the amplitude should be smaller because the string is (dispalcement) is displaced lesser if the mass is removed

By the time the string breaks the metal strip is already deflected downwards to its maximum deflection so your reasoning makes no sense. The strip will oscillate around the new equilibrium position which is further up since the mass is removed. That means the extreme position is further away from the equilibrium position increasing the amplitude.

What factors affect the amplitude of a string when it breaks?

There are several factors that can affect the amplitude of a string when it breaks. These include the tension of the string, the material and thickness of the string, and the type of force being applied to the string.

Can the amplitude of a string vary when it breaks?

Yes, the amplitude of a string can vary when it breaks depending on the factors mentioned previously. Additionally, the location of where the string breaks can also affect the amplitude.

Does the amplitude of a string affect the sound it produces?

Yes, the amplitude of a string can affect the sound it produces. A string with a larger amplitude when it breaks will produce a louder sound compared to a string with a smaller amplitude.

How is the amplitude of a string measured when it breaks?

The amplitude of a string when it breaks can be measured using various techniques such as high-speed cameras, accelerometers, or by analyzing the frequency spectrum of the sound produced.

Can the amplitude of a string be predicted before it breaks?

Yes, the amplitude of a string can be predicted before it breaks by using mathematical models and simulations. However, the exact amplitude may vary depending on real-world conditions and variables.
