5.

If the pitch is 6 cm and rivet value is 4 tonnes, the number of rivets required for a riveted connection carrying an eccentric load of 15 tonnes at a distance of 30 cm from the centre line, is

 [A]. 6 [B]. 8 [C]. 10 [D]. 12 [E]. 15

 Swati Chourasia said: (Jun 28, 2013) Strength of rivet in shearing and bearing are calculated and the lesser value among two is known as rivet value.

 Balkaran Sidhu said: (Jan 18, 2014) After calculating rivet value, No.of rivets = total load/ rivet Value.

 Deepanshu said: (Aug 22, 2014) (6M/lpR)^1/2. (6x30x15/2x6x4)^1/2. 7.5 answer. 8 rivet.

 Soumyadip said: (Jun 6, 2015) I do find out the formula for tearing the plate is P1 = S1(P-d)t. Here S1 is the allowable tensile stress, p=pitch, d=dia, t=thickness of plate and for the shearing of the rivet is P2=Ss (area of one rivet=0.785*d^2). Here Ss is the allowable shear stress of the rivet material. So, from this two formula I don't know the "tensile stress" and "shear stress" and "dia of rivet", how can I determine the strength of rivet? Please suggest me. Thank you.

 Gurpreet Singh said: (Aug 7, 2015) The simple method to find no. of rivet is-it is the question of bracket connection so in this connection same no. of rivets are required on each flange to connect the bracket. So each side required. Rivets are = 15/4 = 3.75 = 4 rivets each side, so total no. of rivets required both side for connection are = 8.

 Agni said: (Sep 29, 2016) What is the formula for strength in shearing and bearing?

 Saurabh Pal said: (Oct 20, 2016) According to me, Mri/(nri2) + p. n = 15

 Sintu Paul said: (Mar 26, 2017) @Deepanshu. How I = 2? Explain.

 Naveen Pal said: (Jul 29, 2017) => 6m/snRv. Where m =p*e, S pick line, Rv rivet value, Answer is 7.5 = 8.

 Sejal said: (Aug 14, 2017) What is the value of s?

 Hanu said: (Nov 11, 2017) @Deepansu it meane 2 line vertical and Rivet is 16 according to formula (you take m =2) and in 1 line 8 rivet.

 Asif Ali said: (Nov 11, 2017) 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).

 Zing Zing said: (Jan 19, 2018) Total Revit will be 15 or 16 but if it is said that rabbit in one line then it will be 8 or 7.

 Siraj said: (Dec 31, 2019) @Asif Bhai, amazed with your explanation. :).

 Jayapriya said: (Apr 18, 2020) Thank you all for giving the explanation.
