Free General Contractors License MCQ Questions and answers — Questions and Answers
Question 1: What kind of screws are utilized for light-gauge steel and gypsum installation?
- Type S screws (Correct answer)
- Type U screws
- Type U screws
- Type R screws
Correct answer: Type S screws
Type S screws are specifically engineered for fastening gypsum board to light-gauge steel studs or channels. They feature a sharp point for easy penetration and fine threads that provide a secure grip in thin metal, preventing stripping and ensuring a strong attachment. Their design is optimized for the specific requirements of drywall and light-gauge steel framing applications.
Question 2: The majority of a building's _____ load is often provided by the structural members' self-weight.
- Wind
- Heavy
- Live
- Dead (Correct answer)
Correct answer: Dead
Dead load refers to the permanent, stationary weight of a building's structural components and fixed attachments. This includes the self-weight of structural members like beams, columns, walls, and the roof, as well as fixed equipment and finishes. Unlike live loads (temporary, movable weights) or wind loads (external forces), dead loads are constant and must be accounted for in all structural design calculations.
Question 3: Which of the following roof designs best fits this description: a roof with two slopes on each of its four sides, the lower slope being steeper than the top slope?
- Mansard (Correct answer)
- Salt Box
- Side-gabled
- Pavilion-hipped
Correct answer: Mansard
A Mansard roof is characterized by having two slopes on each of its four sides, with the lower slope being significantly steeper than the upper slope. This distinctive design often incorporates dormer windows on the lower, steeper section, maximizing usable attic space and creating a unique architectural aesthetic. It is a defining feature of the Mansard architectural style.
Question 4: What is the definition of Ductility?
- Bending deformation, i.e., deformation by increasing curvature.
- Ductility is similar to the concept of support, except that connection refers to
- Ductility generally refers to the amount of inelastic deformation. (Correct answer)
- A system of forces composed of two equal forces of opposite direction, offset by
Correct answer: Ductility generally refers to the amount of inelastic deformation.
Ductility is a material property that describes its ability to undergo significant plastic (inelastic) deformation under tensile stress before fracturing. It quantifies how much a material can stretch, bend, or be drawn into a wire without breaking, allowing for considerable deformation beyond its elastic limit. This characteristic is crucial in engineering as ductile materials can absorb energy and provide warning signs of failure before catastrophic collapse.
Question 5: Regarding trusses, Which of the following statements is untrue?
- Trusses are never used as repetitive lightweight members, such as steel bar (Correct answer)
- The trusses are often used as visual or spatial elements.
- Trusses are also used for heavily loaded long spans requiring more structural
- Trusses are not limited to planar assemblies, and can be arranged as
Correct answer: Trusses are never used as repetitive lightweight members, such as steel bar
The statement that trusses are never used as repetitive lightweight members, such as steel bar, is untrue. Trusses, particularly steel bar joists, are very commonly used as repetitive lightweight structural members for roofs and floors in various types of buildings. Their triangulated geometry allows them to efficiently span long distances while minimizing material use and weight, making them an economical and effective choice for such applications.
Question 6: Select the appropriate term from the definition below: ______ happens in loosely packed saturated sand when seismic shaking compacts the sand, increasing the surrounding water's pressure. The sand grains bear no net pressure and can pass one another because the water's pressure can increase to the point where it absorbs all of the stress in the soil. <br>
- Saturation
- Dissipation
- Liquefaction (Correct answer)
- Indemnification
Correct answer: Liquefaction
Liquefaction is a phenomenon that occurs in saturated, loose granular soils, typically during seismic shaking. The shaking causes the soil particles to rearrange and compact, leading to a rapid increase in pore water pressure. When this pressure becomes high enough to absorb all the stress in the soil, the sand grains lose contact and the soil temporarily loses its strength and stiffness, behaving like a liquid.
Question 7: Find the right phrase to match the definition below: someone who has agreed to take on another's obligations, particularly someone who takes on debts or obligations in the case of default. <br>
- Privity
- Surety (Correct answer)
- Compensation
- Quittance
Correct answer: Surety
A surety is an individual or entity that legally agrees to be responsible for the fulfillment of another party's obligations, especially financial debts or contractual duties, in the event of their default. In construction, a surety bond guarantees that a contractor will complete a project according to the contract terms. If the contractor fails to perform, the surety is then obligated to ensure the project's completion or compensate the owner.
Question 8: What is the acronym CSI?
- Construction Source Institute
- Construction Science Institute
- Construction SPEX Institute
- Construction Specifications Institute (Correct answer)
Correct answer: Construction Specifications Institute
CSI stands for the Construction Specifications Institute. It is a national association dedicated to improving the communication of construction information through standardized formats and practices. Their most well-known contribution is MasterFormat, a widely used system for organizing construction specifications and other project information.
Question 9: Select the term that best describes the definition of the following definition: term used to define hand-operated, portable and stationary firefighting equipment for use in buildings. The phrase also refers to fire hose reels, internal fire hydrants, fire service hose, and nozzles in addition to fire extinguishers that use water, carbon dioxide, foam, and dry powder. <br>
- FEXT (Correct answer)
- FRSA
- FSPR
- ASHRAE
Correct answer: FEXT
FEXT is an acronym that refers to Fire EXtinction Technology or equipment, encompassing various hand-operated, portable, and stationary firefighting devices used in buildings. This includes not only fire extinguishers (water, CO2, foam, dry powder) but also fire hose reels, internal fire hydrants, and associated hoses and nozzles. It describes the comprehensive range of immediate fire suppression tools available within a structure.
Question 10: How far apart does masonary veneer need to be from sheathing? <br>
- .5 inch
- 1.5 inch
- 1 inch (Correct answer)
- 2 inch
Correct answer: 1 inch
Building codes typically require a minimum 1-inch air space, also known as a weep space, between masonry veneer and the structural sheathing. This gap is crucial for allowing any moisture that penetrates the veneer to drain downwards and exit through weep holes, preventing it from reaching and damaging the building's interior structure. It also provides ventilation, helping the wall assembly to dry out.
Question 11: __________ is the amount of unused latex paint in solidified form. <br>
- Flammable
- A hazardous waste
- A non-hazardous waste (Correct answer)
- Corrosive
Correct answer: A non-hazardous waste
Once latex paint has solidified, the water content has evaporated, leaving behind a solid, inert material. In this form, latex paint is generally classified as a non-hazardous waste. It no longer poses the same environmental risks as liquid paint and can typically be disposed of with regular household trash, unlike flammable or corrosive hazardous wastes.
