Homework Help Overview

The discussion revolves around finding the period of a vibrating system given the mass and time for vibrations. The original poster presents a scenario involving a metal plate attached to a platform, which vibrates in simple harmonic motion. The problem includes a chart with mass values and corresponding average times for vibrations.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the relationship between period and frequency, noting that they are inverses. There is uncertainty about how mass factors into the calculation of the period. Some participants suggest that the original poster clarify their question and the context of the problem.

Discussion Status

The discussion is ongoing, with participants exploring the implications of the provided data and questioning the role of mass in determining the period. Guidance has been offered regarding the need to fill in the table based on the average time for vibrations before considering the relationship with mass.

Contextual Notes

The problem includes a chart with mass values ranging from 0.10 to 0.50 kg and corresponding average times for ten vibrations. The table also contains columns for period and T^2, which are currently blank. There is a suggestion that the mass may not be necessary for filling in the period column initially.

Homework Statement



Hey guys I am not sure how to find the period when I am given the mass and the time, for example mass= .10 k and Time for vibrations= 8.86s Find the Period

Homework Equations



Im not sure maybe f = 1/t

The Attempt at a Solution



No idea how to incorporate mass in this. Please help. Thanks a lot

The problem statement is a bit unclear; but for a given periodic motion, period and frequency are inverses of each other and mass has nothing to do with it.
 
Oh I am sorry about that, well first the problem says there is a metal plate attached to the end of a platform and can be used to measure mass. when the free end of the plate is pulled down and realeased it vibrates in simple harmonic motion with a period that depends on the mass attached to the plate. Then we have a chart with 4 coulums, the first the mass which goes from .10 to .50, then the next coulum says avg time for ten vibrations and starts from 8.86 to 17.7 corresping to each mass going up by .10. The nect two coulums are blank first one saying period and the last saying T^2. I hope that helps

It sounds like you are being asked to fill in a table. I think I can see what is going on, but I think you need to be clear about the question you are asking.

As you have described it, you should be able to fill in both columns without using the mass. After you have done this, then you may be in a better position to find an association between the period T and the mass.
