Steel part 4 slide 20-73 part 1

What is the nominal diameter of a rivet?

• Diameter of hole after riveting

• Cold shank diameter before driving

• Diameter of head

• Effective shear area

The gross diameter of a rivet is

• Always smaller than nominal diameter

• Equal to the hole diameter

• Calculated from shear strength

• Measured after driving

If nominal diameter ≤ 25 mm, the gross diameter is

• Nominal + 1 mm

• Nominal + 1.5 mm

• Nominal + 2 mm

• Nominal + 2.5 mm

According to Unwin’s formula, the rivet diameter (d) is

• 1.2t

• 1.5t + 4

• 6.05√t

• 50t – 2

Which formula is used when t < 15 mm according to French formula?

• d = 1.5t + 4

• d = √(50t – 2)

• d = 2t

• d = t + 6

According to German formula, d =

• 6.05 √t

• 1.5t + 4

• √(50t – 2)

• 3t + 2

Which of the following is a standard available nominal diameter of rivet?

• 11 mm

• 13 mm

• 27 mm

• 35 mm

What is the minimum pitch for rivets as per IS 800-1984?

• 2.0d

• 2.5d

• 3.0d

• 1.5d

What is the maximum pitch allowed as per IS 800-1984?

• 32t or 300 mm

• 30t or 300 mm

• 24t or 250 mm

• 20t or 280 mm

In tension members, maximum pitch is

• 12t or 200 mm

• 20t or 200 mm

• 16t or 200 mm

• 10t or 150 mm
