Q1:

A structural member carrying a pull of 700 kN is connected to a gusset plate using rivets. If the pulls required to shear the rivet, to crush the rivet and to tear the plate per pitch length are respectively 60 kN, 35 kN and 70 kN, then the number of rivets required will be

A 22

B 20

C 18

D 12

ANS:B - 20

The number of rivers required = force/Rivit value.

Rivit value = min value of shearing, bearing and tearing.

So,

700/35= 20. (3)
