Calculating Most Probable Point of Rupture on a Falling Pole

Click For Summary

Homework Help Overview

The problem involves a thin uniform pole of length 30 m that is pivoted at one end and is falling. The task is to calculate the most probable point of rupture on the pole during its fall. The subject area pertains to dynamics and material strength in physics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants express uncertainty about how to initiate the problem and seek clarification on the expected outcome. Some discuss the forces acting on the pole during its fall and how these might contribute to the rupture point.

Discussion Status

The discussion is ongoing, with participants sharing their confusion and lack of direction. One participant has provided additional insights regarding the forces acting on the pole, suggesting a potential line of reasoning, but no consensus or clear approach has emerged yet.

Contextual Notes

Participants note the absence of a figure or additional information that might clarify the problem setup, which contributes to their uncertainty in addressing the challenge.

Homework Statement



A thin uniform pole of length 30 m is pivoted at the bottom end. Calculate the most probable point of rupture on the pole as the pole falls.

Homework Equations


I'm really not sure how to start.

The Attempt at a Solution


None, our professor gave us this as a challenge problem and I don't believe it is something I should know taking general physics. Clarification on even where to start would be nice.
 
Physics news on Phys.org
Have you found out how to solve this yet? I have no idea.
 
Still nothing.
 
Damn. I'm not even sure what this is supposed to look like. No figure or anything.
 
So I got some more information if anyone still is helping.

while the pole is falling, at any location of the pole there are forces that try to snap the pole. One goes up perpendicular to the pole and the other comes down perpendicular to the pole. That is why an old fragile pole breaks down while its falling full-length. These forces snap the pole into two pieces.

I'm still not exactly sure how to go about finding the rupture point off of this so it be great for help.
