WebbThe pitch of each row of rivets is 90mm. The rivets are 25 mm in diameter. The permissible stresses are follows: πt= 140MPa; π= 110MPa; πc= 240MPa Given π = 90ππ π = 25ππ π‘ = 16ππ ππ‘ = 140πππ β 140π/ππ2 π = 110πππ β 110π/ππ2 ππ = 240πππ β 240π/ππ2 Answer 1) Tearing of rivets ππ‘ = (π β π)π‘ Γ ππ‘ = (90 β 25)16 Γ 140 = (65) Γ 2240 = 145600π β πππ, πππ΅ WebbIt is also important that the axial pitch (p a ) is maximised (see above note )to ensure that the weakest section of the plate is through a row of holes Rivet Shear The rivet shear calculation is Ο = F / ( n p d 2 /4 ) Ο = Shear Stress (MPa) d = rivet diameter (mm) F = Total Axial Force (N) n = Number of Rivets Plate Tensile Stress

WebbA rivet may fail either due to its shearing off or due to its crushing. Thus, while calculating the strength of a rivet we see as to how much resistance it can offer. The resistance offered by a rivet is known as its strength or the value of the rivet. Following two values of a rivet are important from the subject point of view: 1. WebbRivet pitch is the distance between the centers of neighboring rivets in the same row. The smallest allowable rivet pitch is 3 rivet diameters. The average rivet pitch usually ranges from 4 to 6 rivet diameters, although in some instances rivet pitch could be as large as 10 rivet diameters. Webb(v) Pitch of the rivet, P= 50 mm (vi) Efficiency of the riveted joint n= 69.33%. Problem 2 A single riveted lap joint is to be made of 10 mm plates.
