Homework Statement

Torque calculation

Relevant Equations

F=(1/2)*ρ*(v^2)*A

Hi :)

I have to mount solar panels to columns. And for the stress calculations, I can't calculate the torque :(

Could you help me out?

Your relevant equation for calculating the wind force on the panel is missing the drag factor (shape factor).
How is the plate supported on the column?
What have you tried?
