Structural Elements and Load Quiz

What are the different types of structural elements?

• beams, columns, slabs, walls, foundations, and roofs

• plumbing, electrical, HVAC, insulation

• doors, windows, stairs, partitions

• bricks, mortar, steel, concrete

How is load distributed in beams?

• Load is distributed through compression and tension forces.

• Load is distributed through torsion forces.

• Load is distributed through friction forces.

• Load is distributed through bending and shear forces.

Explain the behavior of columns under load.

• Columns under load can remain unaffected and maintain their shape even if the load exceeds their capacity.

• Columns under load can buckle, bend, or collapse if the load exceeds their capacity.

• Columns under load can shrink and contract if the load exceeds their capacity.

• Columns under load can stretch and elongate if the load exceeds their capacity.

What is stress and strain in structural elements?

• Stress is the external force experienced by a structural element due to internal loads, while strain is the deformation or change in shape of the element caused by the stress.

• Stress and strain are the same thing and can be used interchangeably in structural engineering.

• Stress is the internal force experienced by a structural element due to external loads, while strain is the deformation or change in shape of the element caused by the stress.

• Stress is the deformation or change in shape of a structural element caused by external loads, while strain is the internal force experienced by the element.

Name the failure modes of structural elements.

• buckling, bending, shear, torsion, fatigue, creep

• compression, tension, deflection

• vibration, resonance, instability

• corrosion, rusting, oxidation

Which type of structural element is designed to resist bending moments?

• slab

• wall

• beam

• column

What is the purpose of load distribution in beams?

• To evenly distribute the applied load along the length of the beam.

• To reduce the strength and stability of the beam.

• To concentrate the load at specific points along the length of the beam.

• To increase the overall weight of the beam.

How does the behavior of columns change under different load conditions?

• The behavior of columns changes by experiencing different levels of stress and strain.

• The behavior of columns changes by experiencing different temperatures.

• The behavior of columns does not change under different load conditions.

• The behavior of columns changes due to changes in their material composition.

Define stress in structural elements.

• Temperature changes

• Internal forces or reactions

• Material properties

• External forces or reactions

What is the relationship between stress and strain in structural elements?

• Stress is inversely proportional to strain

• Stress and strain are unrelated

• Stress is proportional to the square of strain

• Stress is directly proportional to strain
