1. In concrete mix design, what does a lower water-to-cement (w/c) ratio primarily result in? → Higher strength and improved durability
2. What is the minimum specified yield strength of ASTM A992 steel, the standard for wide-flange structural shapes? → 50 ksi
3. When was the Zachry Engineering Building originally constructed? → 1970s
4. What structural system uses diagonal members to resist lateral forces in a steel frame building? → Braced frame
5. Which of these structures was created by civil engineers first? → Egyptian pyramids
6. What is the role of a mechanical engineer? → To oversee the construction and installation of mechanical systems
7. What is the primary model building code used as the basis for construction regulations in most US states? → International Building Code (IBC)
8. What is the purpose of a building automation system (BAS) in HVAC operations? → To centrally monitor and control all mechanical and electrical building systems
9. Which heat transfer fluid is commonly circulated through chilled water HVAC systems? → Chilled water at 40–45°F
10. What does the term 'ductility' mean in the context of seismic structural design? → The ability of a structure to deform inelastically without sudden failure
11. What is the purpose of an economizer in an HVAC air handling unit? → To use outdoor air for free cooling when conditions are favorable
12. What do electrical and computer engineers design and implement? → Information systems and hardware
13. Which of the following best describes the size distribution of a whole? → Proportion
14. What is the minimum clearance required between electrical panelboards and the floor per the NEC? → 6 feet 6 inches
15. What is the typical compressive strength range of normal-weight concrete used in standard building construction? → 3,000–5,000 psi
16. What unit is used to measure the cooling capacity of HVAC equipment? → Ton of refrigeration
17. What is the significance of the moment of inertia (I) for a structural beam? → It measures the beam's resistance to bending — higher I means less deflection
18. What structural phenomenon occurs when a slender column buckles before reaching its material yield strength? → Euler buckling (elastic buckling)
19. Which material property allows structural steel to undergo large plastic deformations before fracture, making it valuable in seismic design? → Ductility
20. What refrigerant is widely used in commercial HVAC systems as a replacement for R-22? → R-410A
21. What is the concept of tributary area in structural load calculations? → The floor area whose load is supported by a particular structural member
22. What is the primary function of a Variable Air Volume (VAV) box in an HVAC system? → To modulate the volume of conditioned air delivered to a zone
23. What is net-zero energy building (NZEB) design? → A building that generates as much renewable energy annually as it consumes from the grid
24. Which type of pump is most commonly used to circulate chilled water and hot water in HVAC hydronic systems? → Centrifugal pump
25. Who oversaw the Great Wall of China's construction? → General Meng
26. What is the name of the new building at the University of Illinois? → Electrical and Computer Engineering Building
27. The eyes should be shielded when using a grinder by: → Wearing goggles
28. What is the standard voltage for single-phase residential electrical service in the United States? → 120/240V
29. A structure's lowest point where the load is transferred to the ground is referred to as → Superstructure
30. What is the purpose of rebar stirrups in a reinforced concrete beam? → To resist diagonal shear stresses and confine longitudinal reinforcement
