Question 1

In HVAC design, what does 'sensible heat ratio' (SHR) represent?

Accepted Answer

The ratio of sensible heat to total (sensible + latent) heat load

Answer

SHR is the proportion of sensible cooling to total cooling load, indicating how much of the load involves temperature change versus moisture removal.

Question 2

What does the R-value of insulation measure?

Accepted Answer

Thermal resistance to heat flow per unit area

Answer

R-value (h·ft²·°F/BTU) measures a material's resistance to conductive heat flow; higher R-values indicate better insulating performance.

Question 3

What is the purpose of a 'control joint' in masonry construction?

Accepted Answer

To create a pre-defined plane of weakness preventing random cracking

Answer

Control joints are intentional weakened planes in masonry that concentrate shrinkage and thermal cracking at predictable locations.

Question 4

Which foundation type is most appropriate when soil bearing capacity is very low and loads must be transferred to deeper, competent strata?

Accepted Answer

Pile foundation

Answer

Pile foundations transfer building loads through weak upper soils to deeper bearing strata via end bearing or skin friction.

Question 5

In structural steel, what is the difference between a 'compact' and 'non-compact' section?

Accepted Answer

Compact sections can reach full plastic moment without local buckling; non-compact sections cannot

Answer

Compact sections have width-to-thickness ratios below limits that allow full plastic hinge formation; non-compact sections experience local buckling before full plasticity.
