The illustrated one-rivet joint carries transverse force F. Ignore rivet bending; allowable shear stress is τ and rivet diameter d. Find minimum d. All quantities use SI units.
The forked outer member places the rivet in double shear. Total resisting area is2(πd²/4)=πd²/2. Set F/(πd²/2)=τ and solve d=√[2F/(πτ)], B. Single-shear sizing would use only one circular area.
