DTrue only for lap joints
Answer
Correct Answer: False
Explanation
ConceptDesign checks for riveted joints independently evaluate shear, bearing/crushing, and tearing. The required number based on shear strength generally differs from that based on bearing strength; the governing (larger) requirement is adopted.
ReasoningNshear = Load / (n·τallow·Ashear)Nbearing = Load / (σb,allow·d·t)Since τallow, σb,allow, and geometry differ, counts seldom match exactly.
