## Homework Statement

i'm not sure how to calculate the shear stress at point F and point G . I know that shear stress has formula of $$ \tau = VQ/It $$

The maximum shear force that i calculated earlier is V = 205kN , Ixx = 2.1x10^-4

for Q at $$\tau$$ at F , i have (205x10^3)(260x10^-3)(50x10^-3)(98.5-25)(10^-3) / (2.1x10^-4)(260x10^-3)

for Q at $$\tau$$ at G , i have (205x10^3)(250x10^-3)(50x10^-3)(50+125-98.5)(10^-3) / (2.1x10^-4)(260x10^-3)

Is my ans correct ?
