Homework Statement
Question 3: The beam is supported by a pin at A and a short link BC, as shown in Figure 3.0. Determine the maximum magnitude P of the loads the beam will support if the average shear stress in each pin is not to exceed 80 MPa. The diameter for each of the pins is 18 mm.

I just wanted to get an idea if i'm way off. Really I don't know how to proceed past finding the required shear force in the pins to shear them.
PS: Sorry for my horrible english and writing skills.
