AI Thread Summary

The discussion revolves around calculating critical load in structural analysis, specifically addressing confusion about the correct stress value to use. The original poster questions whether to use a maximum stress of 250 MPa multiplied by an area of 5500, or if the author’s use of 59.4 MPa is appropriate. Clarification is sought on the rationale behind the choice of stress values in the calculations. Participants are encouraged to provide insights or corrections regarding the methodology. Understanding the correct approach to critical load calculations is essential for accurate structural analysis.

Homework Statement

in the 3rd photo , i m having problem finding the critical load

Homework Equations

The Attempt at a Solution

to find the critical load , we should use the maximum stress multiply by the area which is 5500(250MPa) , am i right ? why the author used 59.4MPa(5500) ? is it wrong ?
