Homework Help Overview

The original poster is working on an assignment related to the physics of musical instruments, specifically focusing on drums. They are seeking a formula that explains how drums produce sound but have encountered difficulties in finding relevant information.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants suggest searching for terms related to drumhead vibrations and standing waves. The original poster expresses frustration over time constraints and the challenge of understanding complex equations.

Discussion Status

Some participants have provided suggestions for search terms that may lead to useful information. The original poster acknowledges the difficulty of the assignment and their limited understanding of the mathematical concepts involved.

Contextual Notes

The original poster is under time pressure, needing to complete multiple questions within a limited timeframe. They also mention a lack of familiarity with calculus, which may impact their ability to understand certain equations related to drum physics.

Homework Statement


Assignment to create and explain the physics behind a musical instrument, I am doing a drum. I need to find a formula that governs how it produces notes, and can't find one (been searching for atleast an hour now with no luck). Any help would be much appreciated!


Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
A whole hour! Wow!

Search some more under headings like "drumhead vibrations", "vibration of a circular membrane," and perhaps "tympani".
 
It is when its spent looking for an answer for 2 of the required questions and you have 4 hours to finish all 15. Thanks for the tips though.

Wow. Must be a pretty difficult take-home final. 4 hours for 15 questions. Um, or did you wait until the last minute to start the assignment? Whatever, welcome to the PF anyway.

Another search term (or look in your text) is "standing wave".
 
Last moment for a worksheet we had to hand in, need much more detail in a presentation to go with the actual drum. I found one equation last night but don't understand it (in 11th grade, don't learn calaculus until next year). I'll try to find something better with that, thanks!
