Question

n the figure below, a member is subjected to an axial force P. If the cross sectional area of the member is denoted as AB, then the maximum value of its normal stress  occurs when:


 

   

∅ = 00
   

∅ = 300
   

∅ = 450
   

∅ =900
In the figure below, a member is subjected to an axial force \( P \). If the cross-sectional area of the member is denoted as \( AB \), then the maximum value of its normal stress \( \sigma_n \) occurs when: - Diagram: - A rectangular member is depicted with an axial force \( F \) applied at both ends. - A line \( AB \) represents the cross-sectional area, at an angle \( \phi \) with the horizontal. - The angle \( \phi \) is shown between the line \( AB \) and the direction of the force. Choose the correct angle \( \phi \): - \( \phi = 0^\circ \) - \( \phi = 30^\circ \) - \( \phi = 45^\circ \) - \( \phi = 90^\circ \)
