A rivet of \( 4 \) mm diameter has a single-shear allowable stress of \( 220 \) MPa. Its shear strength is nearest to

  • A.2.8 kN
  • B.5.5 kN
  • C.1.4 kN
  • D.11.0 kN

Answer: A

The area is \( \pi \times 0.002^2 = 1.257 \times 10^{-5} \) m\( ^2 \), so the strength is \( 220 \times 10^6 \times 1.257 \times 10^{-5} = 2765 \) N. Rivet pitch in a seam follows directly from dividing the shear flow by a figure of this kind.
