Steel part 6 slide 1 to 30 questions

What is a bolt?

• A cylindrical tube

• A steel pin with a head at one end and threads at the other

• A round plate

• A welding rod

Which part of a bolt is the smooth, unthreaded portion?

• Thread

• Shank

• Nut

• Runout

What type of bolts are used in light structures under static load?

• HSFG bolts

• Black bolts

• Rivet bolts

• Stainless bolts

The area where the shank meets the head of a bolt is called the:

• Thread

• Runout

• Radius

• Grip length

What is the function of high-strength friction grip (HSFG) bolts?

• Allow slip in the joint

• Eliminate slip by friction

• Used only in temporary joints

• Cannot withstand high loads

Which IS code lays down the specification for high-strength bolts?

• IS 800:2007

• IS 3757:1985

• IS 456:2000

• IS 2720:1993

What is the most commonly used bolted joint?

• Welded joint

• Lap joint

• Butt joint

• Grooved joint

Which failure occurs when the bolt is crushed around its semi-circumference?

• Shear failure

• Bearing failure

• Tension failure

• Block shear failure

Which failure in bolted joints is least likely to occur in practice?

• Shear failure

• Tension failure

• Bearing failure of bolts

• Tearing failure of plates

What is the main advantage of high-strength bolts?

• High noise during tightening

• Load transfer through friction

• Only used in temporary joints

• Needs hammering
