tao = V/A

The Attempt at a Solution

I went ahead and solved the force at BC and the x and y components at A, but I feel as though my solutions are incorrect. At BC I have F = 825 kN (up and to the left), A_x = 714.5 kN positive, A_y = 247.5 kN downward. I don't know how to solve the pins from here. The correct answer at each pin is 324MPa. I found the area to be 508.94mm^2 but am unable to find what force is pulling on each pin.

ptguard1: Your area is correct. Your reaction forces are currently incorrect. If you want to show your work, someone might check your math.

I recalculated my solutions and found my mistake. F at BC = 165 kN (up and to the right), A_x = 142.89 kN to the right, A_y = 82.5 kN up. The issue I'm having is solving for the shear stress in the pins. I don't understand why all of the pins would have the same result.

For the pin at A, I interpret it as shown in the attached image

I used the equation A_x/Area, but i know that I need the force to be 165kN
