Riveted joint design check: equality of rivets in shear and crushing? Statement to evaluate: ‘‘In a riveted joint, the number of rivets working in shear must be equal to the number of rivets working in crushing.’’ Choose the correct option (True/False).

Mechanical Engineering Machine Design Difficulty: Easy
Choose an option
  • A
    True
  • B
    False
  • C
    True only for double-strap butt joints
  • D
    True 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.
