The number of rivet lines is not provided. Then how to predict?

Total Revit will be 15 or 16 but if it is said that rabbit in one line then it will be 8 or 7.

Given Data:
Pitch = p = 6cm
Rivet Value = R = 4tonnes
No.of Rivets = n = ?
Eccentric Load=P=15tonnes
Distance b/w Centre Line [ i-e Centroid (G) ] and Line of action of Eccentric Load (P) = e = 30cm.
Sol:
Formula:
n = (6M/R.p)^1/2 -------------(1).
Here,
External Moment=M=P.e/No.of Vertical Rows -------------------(2).
[I don't know why but according to the situation], The No. Of Vertical Rows = 2.
So, Now ,
Putting the values in eqn (2),
M = 15 tonnes*30cm/2.
M = 225 tonnes-cm.
Now ,
Putting all the values in eqn (1).
n=(6*225 tonnes-cm/4tonnes*6cm)^1/2.
n=(56.25)^1/2.
n=7.5.
Take it as n=8rivets.
So,
No. of Rivets=n=8 (And).
Pitch = p = 6cm

@Deepansu it meane 2 line vertical and Rivet is 16 according to formula (you take m =2) and in 1 line 8 rivet.

=> 6m/snRv.
Where m =p*e,
S pick line,
Rv rivet value,
Answer is 7.5 = 8.
Where m =p*e,
S pick line,
Rv rivet value,
Answer is 7.5 = 8.
