Steel Structure Design - Engineering

Q1:

Strengths of a rivet in single shearing, in bearing and in tearing are 3425 kg, 4575 kg and 5025 kg respectively. If the load in the member is 35 tonnes, the number of rivets required, is

A 10

B 11

C 12

D 13

E 15

ANS:D - 13

The answer is wrong!

Rivet value is taken as minimum value of Shearing, Bearing and tearing!
No of rivets = Force/Rivet value.
Then the answer is 10.21.
