Young's Modulus of a Banana leaf

Click For Summary

Discussion Overview

The discussion centers around the Young's modulus of banana leaves, specifically in the context of calculating the maximum load they can bear. Participants explore the relationship between Young's modulus and material strength, as well as the methods for determining these properties experimentally.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the Young's modulus of banana leaves in MPa, indicating a need for this information for an assignment.
  • Another participant questions the research done by the original poster and asks about the intended application of the Young's modulus measurement.
  • A participant clarifies that Young's modulus relates to the stiffness of the leaf and not directly to the maximum load at failure, suggesting the need for a failure criterion and maximum stress estimation.
  • Another participant reiterates the previous point about Young's modulus and emphasizes the experimental approach to determine maximum load.
  • A later reply provides a reference to a paper on banana fibers, suggesting it may contain relevant information on maximum strength and the need to consider fiber distribution and density for calculations.

Areas of Agreement / Disagreement

Participants express differing views on the relevance of Young's modulus to the maximum load calculation, with some emphasizing its importance while others argue it does not directly apply. The discussion remains unresolved regarding the best approach to determine the maximum load of banana leaves.

Contextual Notes

Participants note the need for additional parameters such as fiber density and cross-sectional area to accurately calculate load, indicating that assumptions about material properties and experimental methods are not fully established.

Welcome to PhysicsForums.

Assuming you're serious (for the moment), what research have you done into this? What is the application that you have in mind?

I am a 2nd-semester student and I have the assignment to calculate the maximum load of banana leaves, I have not mastered how to calculate it, but in my opinion, if I know the young's modulus banana leaves, I will be able to measure the maximum load. Do you know young's modulus from banana leaves? or know other ways to get the maximum load?
 
Ah, since it's for schoolwork, I'll move the thread to the schoolwork forums for you now.

If it were me, I'd start with a Google search using some directed search terms... :wink:
 
It is not related to Young's modulus. Young's modulus applies to the stiffness of the leaf, not to the maximum load at failure. You need a failure criterion, and an estimate of the maximum stress at failure. I suggest somehow doing it experimentally.

That could be harder than you think

 
Here’s a paper on banana fibers

This will give you a maximum strength in the fiber direction. I do not know anything about the distribution of fibers, but I would guess that there is also a weak direction where you are separating the fibers. You will need to find a fiber density and cross sectional area in order to calculate a load.
