What should be taken into account during the manufacturing of steel sections or casting of concrete sections?
The color of the material
The safety of the public
The cost of the material

What do section properties of beams define?
How well the beam can resist bending stress and avoid deflections
The compression strength of the beam
The tensile strength of the beam
The shear strength of the beam
What is the effect of increasing the depth and stacking of beams?
It increases the second moment of area to resist bending stress and large deflections
It decreases the second moment of area
It increases the tensile strength
It decreases the bending stress
Which of the following is a fire-retardant material used in buildings?
Stucco
Gypsum boards
Brick
Glass
Why can't a fire wall on its own stop the spread of fire?
Because it is not made of fire-resistant materials
Because fire can get over, around, or through the wall
Because it is not tall enough
Because it is not part of the building's structure
