(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2. Relevant equations

[tex]\sigma_x = -\frac{M(x)y}{I}[/tex]

[tex]I = \frac{bh^3}{3}[/tex]

3. The attempt at a solution

For point A, I did the following:

[tex]I = \frac{t(2h)^3}{3}[/tex]

[tex]I = \frac{8th^3}{3}[/tex]

[tex]\sigma_x = -\frac{3\tau_0}{4th}[/tex]

[tex]\tau_{yx} = -\tau_0[/tex]

[tex]\sigma_y = 0[/tex]

Are my principal stresses correct for point A? Also, would these principal stresses be the same for Point B?
