Question 1

Which of the following statement is true?&#10;A)lap joint eliminates eccentricity of applied load, butt joint results in eccentricity at connection&#10;B)lap joint and butt joint eliminates eccentricity at connection&#10;C)lap joint results in eccentricity of applied load, butt joint eliminates eccentricity at connection&#10;D)lap joint and butt joint results in eccentricity of applied load

Accepted Answer

Lap joints result in eccentricity because the load path is offset from the main axis of the members being joined, leading to bending moments in addition to direct stress. Butt joints, when properly designed and executed, align the load path directly through the axis of the members, eliminating eccentricity at the connection.

Question 2

In a lap joint, at least______________&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;bolts should be provided in a line.&#10;A)0&#10;B)1&#10;C)2&#10;D)3

Accepted Answer

In a lap joint, at least 2 bolts should be provided in a line to ensure proper load distribution and to maintain the integrity of the joint.

Question 3

Use of lap joints is not recommended because&#10;A)stresses are distributed unevenly&#10;B)eccentricity is eliminated&#10;C)bolts are in double shear&#10;D)no bending is produced

Accepted Answer

Lap joints are not recommended because they result in uneven stress distribution. This can lead to premature failure or inefficiency in the joint's performance.

Question 4

Why is double cover butt joint preferred over single cover butt joint or lap joint?&#10;A)bolts are in single shear&#10;B)eliminates eccentricity&#10;C)bending in bolts&#10;D)shear force is not transmitted

Accepted Answer

Double cover butt joint is preferred because it eliminates eccentricity, ensuring that the load is evenly distributed across the joint, which is not the case with single cover butt joints or lap joints.

Question 5

Clip and seating angle connection is provided for&#10;A)lateral support&#10;B)bending support&#10;C)frictional support&#10;D)hinged support

Accepted Answer

Clip and seating angle connections are typically used to provide lateral support to structural elements, helping to stabilize them against lateral forces.

Question 6

In flexible end plate design, beam is designed for the&#10;A)maximum bending moment&#10;B)shear force&#10;C)torsional moment&#10;D)zero end moment

Accepted Answer

The answer of In flexible end plate design, beam is...

Question 7

which of the following condition is true for web side plate connection?&#10;A)hsfg bolts should be used&#10;B)bolts should be designed to fail by shear of bolt&#10;C)bolts should be designed to fail by bearing of connected plies&#10;D)edge distances must be less than two times the bolt diameter

Accepted Answer

In a web side plate connection, bolts are typically designed to fail by bearing of the connected plies to ensure that the connection can accommodate the loads without premature failure.
