Young's Modulus of a Banana leaf

AI Thread Summary
The discussion centers on determining the Young's modulus of banana leaves, which is essential for calculating their maximum load. Participants emphasize that Young's modulus relates to the stiffness of the leaf and not directly to maximum load at failure, which requires understanding failure criteria and maximum stress. Suggestions include conducting experimental measurements and researching banana fibers for strength data. A referenced paper provides insights into the properties of banana fibers, highlighting the importance of fiber distribution and density in calculations. Understanding these factors is crucial for accurately assessing the mechanical properties of banana leaves.

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.
