Steel part 5 slides 21 to 40 questions

Which type of joint is formed when two parts meet at a groove?

• Lap joint

• Edge joint

• Groove joint

• Corner joint

In a corner joint, two parts are joined:

• At their edges

• At a corner

• End to end

• By overlapping

In an edge joint, the parts are:

• At right angles

• Overlapping

• Parallel at a common edge

• Disconnected

In a lap joint, the two parts:

• Overlap each other

• Meet at a corner

• Are joined at a groove

• Are bolted

The permissible stress in a single V-butt weld is:

• 110 N/mm²

• 150 N/mm²

• 200 N/mm²

• 250 N/mm²

Based on appearance, fillet welds can be:

• Only convex

• Only concave

• Only mitre

• Convex, concave, or mitre

The safe load on a fillet weld depends on:

• Throat thickness only

• Length of weld only

• Shear stress only

• All of the above

Permissible shear stress in fillet welds is taken as:

• 90 N/mm²

• 100 N/mm²

• 110 N/mm²

• 120 N/mm²

Weld symbols are used to:

• Show steel grades

• Indicate welding positions and types

• Calculate stresses

• Specify joint locations only

Assertion (A): Welded connections offer better aesthetics than riveted connections. Reason (R): Welding avoids the need for splice plates and large bolts.

• Both A and R are true, and R is the correct explanation of A

• Both A and R are true, but R is not the correct explanation of A

• A is true, but R is false

• A is false, but R is true
