Rivets are used in WSM method. So why we multiply the load by load factor?
Then answer is 11.
Then answer is 11.

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

The answer should be 11 because;
n = load/rivet value.
n = 35000/3425,
n = 10.2 = 11.
n = load/rivet value.
n = 35000/3425,
n = 10.2 = 11.

Always even num of rivets are provided so 12 num of rivets is required.

1.25 is Factor of safety. FOS= 1.25.

Why 1.25 is multiplied in 35000?

Load Factor of 1.2 gives total load as 35 * 1.2 * 1000 = 42000 kg. Hence the Number of Rivets = 42,000/3425 = 12.26.
So, 13 Rivets are required.
So, 13 Rivets are required.

1.25P/least strength of rivet.
1.25 * 35000/3425 = 12.773.
1.25 * 35000/3425 = 12.773.
