Which of the following is NOT a type of structural analysis:

  1. Static analysis

  2. Dynamic analysis

  3. Plastic analysis

  4. Limit state design


Correct Option: D
Explanation:

Limit state design is a design philosophy, not a type of structural analysis.

The bending moment in a beam is:

  1. The force that causes the beam to bend

  2. The internal force that resists bending

  3. The moment that causes the beam to rotate

  4. The moment that causes the beam to deflect


Correct Option: B
Explanation:

The bending moment is the internal force that resists the bending of a beam.

The shear force in a beam is:

  1. The force that causes the beam to bend

  2. The internal force that resists bending

  3. The force that causes the beam to shear

  4. The force that causes the beam to deflect


Correct Option: C
Explanation:

The shear force is the force that causes the beam to shear.

The deflection of a beam is:

  1. The amount the beam bends

  2. The amount the beam rotates

  3. The amount the beam deflects

  4. The amount the beam shears


Correct Option: C
Explanation:

The deflection of a beam is the amount the beam bends.

The stress in a beam is:

  1. The force per unit area

  2. The moment per unit area

  3. The shear force per unit area

  4. The deflection per unit area


Correct Option: A
Explanation:

The stress in a beam is the force per unit area.

The strain in a beam is:

  1. The change in length per unit length

  2. The change in angle per unit length

  3. The change in volume per unit volume

  4. The change in mass per unit mass


Correct Option: A
Explanation:

The strain in a beam is the change in length per unit length.

The modulus of elasticity of a material is:

  1. The ratio of stress to strain

  2. The ratio of moment to curvature

  3. The ratio of shear force to deflection

  4. The ratio of deflection to strain


Correct Option: A
Explanation:

The modulus of elasticity of a material is the ratio of stress to strain.

The yield strength of a material is:

  1. The stress at which the material begins to yield

  2. The stress at which the material fails

  3. The stress at which the material begins to plastically deform

  4. The stress at which the material begins to creep


Correct Option: A
Explanation:

The yield strength of a material is the stress at which the material begins to yield.

The ultimate strength of a material is:

  1. The stress at which the material fails

  2. The stress at which the material begins to yield

  3. The stress at which the material begins to plastically deform

  4. The stress at which the material begins to creep


Correct Option: A
Explanation:

The ultimate strength of a material is the stress at which the material fails.

The factor of safety is:

  1. The ratio of the ultimate strength to the yield strength

  2. The ratio of the yield strength to the ultimate strength

  3. The ratio of the working stress to the yield strength

  4. The ratio of the yield strength to the working stress


Correct Option:
Explanation:

The factor of safety is the ratio of the ultimate strength to the working stress.

The working stress is:

  1. The stress at which the material begins to yield

  2. The stress at which the material fails

  3. The stress at which the material begins to plastically deform

  4. The stress at which the material begins to creep


Correct Option: A
Explanation:

The working stress is the stress at which the material begins to yield.

The limit state design is:

  1. A design philosophy that ensures that the structure will not collapse

  2. A design philosophy that ensures that the structure will not experience excessive deflection

  3. A design philosophy that ensures that the structure will not experience excessive vibration

  4. A design philosophy that ensures that the structure will not experience excessive cracking


Correct Option: A
Explanation:

The limit state design is a design philosophy that ensures that the structure will not collapse.

The serviceability limit state is:

  1. The limit state at which the structure will collapse

  2. The limit state at which the structure will experience excessive deflection

  3. The limit state at which the structure will experience excessive vibration

  4. The limit state at which the structure will experience excessive cracking


Correct Option: B
Explanation:

The serviceability limit state is the limit state at which the structure will experience excessive deflection.

The ultimate limit state is:

  1. The limit state at which the structure will collapse

  2. The limit state at which the structure will experience excessive deflection

  3. The limit state at which the structure will experience excessive vibration

  4. The limit state at which the structure will experience excessive cracking


Correct Option: A
Explanation:

The ultimate limit state is the limit state at which the structure will collapse.
