Homework Help Overview

The discussion revolves around the behavior of a string and a metal strip in an oscillating system, particularly focusing on the amplitude of oscillation when the string breaks and mass is removed. The subject area includes concepts of oscillations and equilibrium positions in physics.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between mass removal and amplitude, with some suggesting that amplitude should increase while others express confusion about this reasoning. Questions arise regarding the impact of the new equilibrium position on oscillation characteristics.

Discussion Status

The discussion is ongoing, with participants presenting differing views on the relationship between mass removal and amplitude. Some guidance has been offered regarding the new equilibrium position, but there remains a lack of consensus on the implications of this change.

Contextual Notes

Participants are grappling with the assumptions related to the behavior of the system post-mass removal, particularly in terms of how equilibrium positions affect amplitude and oscillation dynamics.

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.
