Question 1

Joints in concrete are used to:&#10;A)reinforce the concrete.&#10;B)control the location of cracks.&#10;C)eliminate cracking, spalling, and scaling.&#10;D)absorb longitudinal load stress.

Accepted Answer

Joints in concrete are used to control the location of cracks by providing a weakened plane where the concrete can crack in a controlled manner. This helps prevent random cracking from occurring and ensures that any cracking that does occur is in a predictable location. Joints also allow for movement in the concrete, which can help prevent cracking due to stress from temperature changes or other factors. However, joints do not directly reinforce the concrete, eliminate cracking, spalling, or scaling, or absorb longitudinal load stress.

Question 2

The purpose of a storm water drainage system is to:&#10;A)carry rain water away from the property.&#10;B)protect the property in case the local community's sanitary sewer system fails, by providing a place for the sewage to go.&#10;C)protect the property from underground springs.&#10;D)do all of the above.

Accepted Answer

The purpose of a storm water drainage system is to carry rainwater away from the property to prevent flooding and damage to the property. B and C are not correct as storm water drainage systems are not used for sanitary sewer backup or protection from underground springs.

Question 3

To seal penetrations of the roof by equipment, __________ is installed under the roofing material and up the sides of the equipment.&#10;A)jointing&#10;B)glazing&#10;C)decking&#10;D)flashing

Accepted Answer

Flashing is typically made of metal and is designed to form a barrier between the equipment and the roofing material. It is installed to prevent water intrusion through gaps or seams between the equipment and the roof. The flashing is installed under the roofing material and extends up the sides of the equipment to ensure a watertight seal.

Question 4

Why is it important for the hotel's maintenance department to keep the blades of the hotel's lawn mowers sharp?&#10;A)If the blades are sharp, the grass is cut, not ripped, and is therefore less susceptible to disease.&#10;B)The engines of the lawn mowers will run smoother if the blades are kept sharp.&#10;C)If the blades are sharp, the lawn mowers will use less gas.&#10;D)The blades are less likely to warp or crack if they are kept sharp.

Accepted Answer

If the blades are sharp, the grass is cut clean and even, rather than being ripped or torn. This protects the quality of the grass, makes it look better, and reduces its susceptibility to disease.

Question 5

An advantage of using universal parking spaces to comply with the ADA is that:&#10;A)no &#34;van accessible&#34; signs are needed.&#10;B)spaces can accommodate either vans or cars.&#10;C)access aisles are not required.&#10;D)a and b

Accepted Answer

Universal parking spaces can serve the needs for both car and van access without the need for separate designated spots. Hence, signages such as "van accessible" are not required. Also, the access aisles may be reduced in size compared to those required for van accessible spots, making the design more flexible. Therefore, both option A and B are correct.

Question 6

To &#34;exercise&#34; a valve is to:&#10;A)thoroughly clean it.&#10;B)fully open and close it.&#10;C)carefully lubricate it.&#10;D)replace it with a new one.

Accepted Answer

To "exercise" a valve means to fully open and close it in order to prevent it from becoming stuck or not functioning properly over time. This helps keep the valve operating efficiently and effectively. While cleaning and lubrication are important maintenance tasks for valves, they are not necessarily part of the process of "exercising" a valve. Similarly, replacing a valve with a new one may be necessary in some cases, but it does not constitute "exercising" the valve. Therefore, the best choice is B.

Question 7

When a concrete slab develops hairline cracks that form a map-like pattern on the slab's surface, the slab is experiencing a condition called:&#10;A)spalling.&#10;B)leaching.&#10;C)crazing.&#10;D)scaling.

Accepted Answer

The description of hairline cracks forming a map-like pattern on the surface of a concrete slab is characteristic of crazing, which is a pattern of small cracks that do not penetrate the full depth of the concrete.

Question 8

Exterior walls should be inspected at least:&#10;A)once every six months.&#10;B)every other year.&#10;C)every five years.&#10;D)every ten years.

Accepted Answer

Exterior walls are exposed to constant weathering and wear, and can develop issues that might affect the structural integrity of the building. Regular inspections every six months can help detect problems early and prevent bigger issues that might require expensive repairs.

Question 9

You are the manager of a downtown restaurant.Recently, you have begun having problems with graffiti being sprayed onto the outside masonry walls of the restaurant.You've just repainted and the restaurant looks great, but you don't want to have to repaint constantly.What can you do to make it easier to clean graffiti off the walls?

A)Apply a mixture of household bleach, vinegar, and water to the walls.
B)Use an alkaline cleaner.
C)Apply a clear acrylic sealer to the walls.
D)There is nothing you can do about this problem, beyond repainting when necessary.

Accepted Answer

Applying a clear acrylic sealer to the walls creates a protective layer that makes it easier to clean off graffiti. The sealer will prevent the paint from bonding with the masonry, making it possible to remove the graffiti with a pressure washer or graffiti remover without damaging the underlying surface. Household bleach and vinegar can damage the surface, and an alkaline cleaner may not be effective in removing all types of graffiti. Furthermore, it is important to note that there are additional measures that can be taken to prevent graffiti, such as installing security cameras or lighting, or working with community groups to create murals or public art that discourage vandalism.

Question 10

Which of the following is not true about a hydraulic elevator system?&#10;A)The car is mounted on a giant piston.&#10;B)Counterweights help the elevator move up and down.&#10;C)Oil pumped into a cylinder raises the elevator.&#10;D)It can only be used in a building of six stories or less.

Accepted Answer

Counterweights are typically used in traction elevators, not hydraulic elevators. Hydraulic elevators move by pumping oil into a cylinder to move the piston and lift the elevator car, without the need for counterweights.
