What are the material properties of structural elements?

• weight, flexibility, brittleness, and conductivity

• density, porosity, magnetism, and thermal expansion

• strength, stiffness, durability, and ductility

• color, texture, transparency, and hardness

Name three types of beams.

• Wooden beam

• Concrete beam

• Simply supported beam, Cantilever beam, Continuous beam

• Steel beam

What are the different types of columns?

• integer columns, string columns, and boolean columns

• primary key columns, foreign key columns, and indexed columns

• text columns, binary columns, and boolean columns

• numeric columns, character columns, and date/time columns

Compare beams and columns in terms of their structural function.

• Columns are horizontal members that carry loads primarily by bending.

• Beams are vertical members that primarily carry compressive loads.

• Beams and columns have the same structural function.

• Beams are horizontal members that carry loads primarily by bending, while columns are vertical members that primarily carry compressive loads.

What are the material properties that affect the strength of structural elements?

• Density, thermal conductivity, electrical conductivity

• Color, texture, odor

• Melting point, boiling point, specific heat capacity

• Young's modulus, yield strength, ultimate tensile strength, ductility, toughness, hardness

What is the purpose of beams in a structure?

• To reduce the overall weight of the structure

• The purpose of beams in a structure is to support and distribute the load.

• To increase the flexibility of the structure

• To provide aesthetic appeal to the structure

What are the advantages of using steel as a material for structural elements?

• Steel is heavy and has a low strength-to-weight ratio

• Steel is strong, durable, fire-resistant, and has a high strength-to-weight ratio.

• Steel is not resistant to fire

• Steel is weak and easily damaged

What are the disadvantages of using timber as a material for structural elements?

• Susceptibility to moisture damage, lack of strength, and limited lifespan.

• High cost, limited availability, and low durability.

• Susceptibility to rot, termite damage, and fire hazards.

• Difficult to work with, prone to warping, and limited design options.

What are the different types of struts?

• Single-strut, Double-strut, Triple-strut

• Hydraulic strut, Pneumatic strut, Mechanical strut

• Fixed strut, Adjustable strut, Removable strut

• Single-acting strut, Double-acting strut, Telescopic strut

What is the difference between a tie and a strut?
