Bearing, shearing, and tearing strength is called Rivet value.
In bearing tearing and shearing value we take always Lower value whichever is less
Here my Rivet value is= 3428kg.
Load is = 35tonnes =35x1000=35000.
Then,
No of Rivet= load/ rivet value.
Then,
35000/3425= 10.22.
We can say 11 rivet.

Then,

We can say 11 rivet.

It is 11. And no need to add FOS for matching with answer.

No of rivet = load/rivet vale.
Rivet value is the least value of bearing and shearing.
SO, n = 35000/3425 = 10.22 say 11.
Rivet value is the least value of bearing and shearing.
SO, n = 35000/3425 = 10.22 say 11.

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

No need to use FOS because of strength is already underestimated.

While calculating the shear and bearing capacity of rivet the factor of safety had been calculated. Is it necessary to consider the factor of safety twice? Please, anyone, tell me.

Yes, I also agree @Deep.
It is no need of FOS.
It is no need of FOS.

Agree @Deep.
It should be 11.
It should be 11.

Guys it's 13.
Take fOS also.
