Test: Structural Fasteners - 1 - Question 1

If the thickness of thinnest outside plate is 10 mm, then the maximum pitch of rivets in tension will be taken as

Detailed Solution for Test: Structural Fasteners - 1 - Question 1

Maximum pitch of rivets in tension = 16t or 200 mm whichever is less,
∴ Pitch = 16 x 10 = 160 mm

Test: Structural Fasteners - 1 - Question 2

When the axis of load lies in the plane of rivet group, then the most heavily loaded rivet will be the one which.

where, Fa is the load shared by each rivet due to axial load and Fm is the shearing load due to moment in any rivet

Detailed Solution for Test: Structural Fasteners - 1 - Question 2

Test: Structural Fasteners - 1 - Question 3

The difference between gross diameter and nominal diameter for the rivets up to 25 mm diameter is

Detailed Solution for Test: Structural Fasteners - 1 - Question 3

Gross diameter
= Nominal diameter + 1.5 mm, φ≤ 25 mm
Gross diameter
= Nominal diameter + 2 mm, φ > 25 mm φ =  Nominal diameter

Test: Structural Fasteners - 1 - Question 4

If the thickness of plate to be connected by a rivet is 16 mm, then suitable size of rivet as per Unwin’s formula will be

Detailed Solution for Test: Structural Fasteners - 1 - Question 4

According to Unwin’s formula nominal diameter of rivet is given by,

Test: Structural Fasteners - 1 - Question 5

According to IS Specifications, the maximum pitch of rivets in compression is

(where t is thickness of thinnest outside plate or angle)

Detailed Solution for Test: Structural Fasteners - 1 - Question 5

Maximum pitch of rivets in compression = 12t or 200 mm whichever is less

Test: Structural Fasteners - 1 - Question 6

Which one of the following is the mode of failure in a fillet weld material?

Test: Structural Fasteners - 1 - Question 7

Load on connection is not eccentric for

Detailed Solution for Test: Structural Fasteners - 1 - Question 7

In the case of double cover butt joint, eccentricity of force does not exist and bending is eliminated whereas it exists in the case of lap joint.

Test: Structural Fasteners - 1 - Question 8

Match List-I (Failure mode) with List-II (Reason) and select the correct answer using the codes given below the lists:
List-I
A. Shear failure of plates
B. Bearing failure of plates
C. Tearing failure of plates
D. Splitting failure of plates
List-II
1. Insufficient edge distance
2. Strength of plate is less than that of the rivets

Detailed Solution for Test: Structural Fasteners - 1 - Question 8

Possible failures of Bolted connection:

1. Tension failure of plate

2. Bearing failure of bolt

3. Shear failure of bolt

4. Shear failure of plate

5. Splitting failure of plate

6. Bearing failure of plate

Out of the above given failures, the last three failures i.e. shear failure, splitting failure and bearing failure of plate are occurred due insufficient end distance and can be prevented by providing proper end distance. For the first 3 failures, we need to design bolted connection.

Test: Structural Fasteners - 1 - Question 9

The centre to centre maximum distance between bolts in tension member of thickness 10 mm is

Detailed Solution for Test: Structural Fasteners - 1 - Question 9

The distance between centres of two adjacent rivets, in a line lying in the direction of stress, shaff not exceed 16t or 200 mm, whichever is less in tension members and 12t or 200 mm, whichever is less in compression member
∴ c/c distance = Lesser of (16 x 10, 200) 
= 160mm.

Test: Structural Fasteners - 1 - Question 10

The type of stress induced in the foundation bolts fixing a column to its footing is

Detailed Solution for Test: Structural Fasteners - 1 - Question 10

The axial force from column needs to be transferred from column to footing and thus, mainly type of stress induced in the foundation bolts is pure tension.
