Which of the following requires flexible ducting that is connect to main ductwork: a)sprinkler branch line b)return air grill c)supply air register d)air handling unit |
c) Supply air registers are often connected to the main ductwork with flexible ducting. This allows some adjustability in the exact location of an air register if its location conflicts with some other ceiling mounted item. The mechanical engineer should be consulted to determine how much the registers can be moved. On the Practicum – refer to your program instructions. |

1walls separating dwelling units (i.e. apartments, dorms,assisted living) 2walls separating hotel guest rooms 3walls separating tenant spaces in covered mall buildings 4corridor walls 5elevator lobbies in institutional or high-rise buildings. |

Which of the following devices would be used to prevent the spread of smoke during a fire? fire damper smoke damper ionization detector fire suppression detector |
fire damper Fire Dampers are used to PREVENT the spread of fire AND smoke.Smoke Dampers are used to RESIST the passage of smoke and air. In a passive control system, smoke dampers close in the presence of smoke to prevent it from circulating through a ventilation opening, transfer or duct, while in an engineered control system, smoke dampers help pressurize the areas around the fire, using floors and walls as barriers.Dynamic fire dampers close when airflow velocity and pressure increases a certain amount, whereas static fire dampers work with HVAC systems designed to shut down automatically in a fire. |

A compact filing system is an example of: a) dead load b) lateral load c) dynamic load d)live load |
d) Live Load Live loads include the loads of people, furniture, snow, and other moving equipment. However dead loads can also include permanent mechanical (moving) equipment also. |

Which is NOT part of a fire suppression system? a) fire extinguisher b) sprinklers c) smoke detectors d) fire damper |
There are 3 parts to a fire protection system: detection, alarm, and suppression. Smokedetectors would fall under detection. The other 3 choices play a part in suppressing a fire, i.e. restrain / contain / stop the fire. |

What is the measure of how well ceilings absorb sound coming over a partition? A) articulation class b) ceiling attenuation class c) speech range absorbption d) impact insulation class |
A) Articulation Class The measure of how well ceilings absorb sound coming over a partition is articulation class. Ratings are based on a 9ft ceiling with 5ft partitions.Articulation class is one of 2 methods used to measure speech privacy in open office environments. Articulation index measures all elements in a room including furniture, partitions, ceiling, sound masking systems, etc. |

In which structural system do large members span between columns with smaller members framed into them? a)open-web joist system b)one-way pan joist system c)beam-and-girder system d)waffle slab system |
c) beam-and-girder system in a beam-and-girder system, large members, called girders, span between columns and small beams are framed into them. The girders span shortened distances because they carry the weight of the beams. The beams span the longer distances and are framed into the girders. |

|
Which of the following would not be considered a dead load? a) mechanical equipment b)floors c)interior walls d)furniture |
d) furniture Live loads include the weight of people, furniture and other movable equipment. |
