Extracted text: A 500 Ib/ft uniform load w is applied to 6 ft rigid horizontal bar CA, pin supported at C in single shear. Link AB is solid and has a 0.25" radius. Pins A, B and C have a 0.2" radius. If the yield shear stress for the pins is 30 ksi and the tension yield stress for the link AB is 50 ksi determine the overall Factor of Safety for the structure.
