Shear Stress in Pins: Solving Forces in 3 Equations

[cwckc7]

Alright so I'm working on my statics homework and am working on Shear Stress. I know that stress is the force divided by the cross sectional area, but how do I do it for these pins? I've solved for the forces in each pin by using the 3 equilibrium equations, can someone nudge me in the right direction?

If you've calculated the reactions and forces in the pins correcty, each of which has components in the x and y directions, then the shear stress is just the resultant force at each of those pins divided by the cross sectional area of the pins, (or twice the cross sectional area if the pin is in double shear).
