## Homework Statement

We all know that $$\tau = VQ/ It $$

how to determine the shear stress at **G** ?

I'm having problem of finding Ay

centroid if the solid that i found earlier is y = 98.5mm

There's a dashed line from G to the bottom . It's making me confused . for Q , should i consider the area either to the left or right of the G ? like the red and orange part

## Homework Equations

## The Attempt at a Solution

so , my working is

Q = Ay = (250x10^-3)(50x10^-3)( 50+125-98)(10^-3) = 9.63x10^-4

Is my concept correct ?

I'm considering the area above the G .
