Machine Design According to I.B.R., when the thickness of the boiler shell (t) is less than 8 mm, then the diameter of the rivet hole (d) is obtained by Equating tearing resistance of the plate to the shearing resistance of the rivets Equating shearing resistance to the crushing resistance of the rivets None of these Equating tearing resistance of the plate to the crushing resistance of the rivets Equating tearing resistance of the plate to the shearing resistance of the rivets Equating shearing resistance to the crushing resistance of the rivets None of these Equating tearing resistance of the plate to the crushing resistance of the rivets ANSWER DOWNLOAD EXAMIANS APP
Machine Design According to Unwin's formula, the relation between the diameter of rivet hole (d) and the thickness of plate (t) is given by (where d and t are in mm) d = 6√t d = 2√t d = √t d = 1.6√t d = 6√t d = 2√t d = √t d = 1.6√t ANSWER DOWNLOAD EXAMIANS APP
