Q: A False statement regarding the assumptions made in the design of riveted joints.
  • A. Stress in a plate is assumed to be uniform
  • B. Rivets are assumed to be stressed unequally
  • C. Bending of rivet is neglected
  • D. Friction between the plates is neglected
Correct Answer: Option B - Assumptions for design of riveted joint– (i) The load is assumed to be uniformly distributed among all the rivets. (ii) The shear stress on a rivet is assumed to be uniformly distributed over its gross area. (iii) The bearing stress is assumed to be uniform between the contact surfaces of plate and rivet. (iv) The bending stress in a rivet is neglected. (v) The rivet hole is assumed to be completely filled by the rivet. (vi) The stress in plate is assumed to be neglected. (vii) The friction between plates is neglected.
