Question 1

When using a telescope such as a transit, one should keep both eyes open to reduce eye strain.

Accepted Answer

Keeping both eyes open while using a telescope, such as a transit, helps to reduce eye strain and fatigue. This technique is called binocular viewing and allows the observer to relax their eye muscles while still maintaining accurate focus on the object being observed.

Question 2

A typical rectangular building with a deep foundation will need __ batter boards.
A) 4
B) 8
C) 12
D) 16

Accepted Answer

Batter boards are used to secure and mark the corners of a building's foundation. For a rectangular building, there will be two lengths and two widths, so four corners total. Each corner will require two batter boards, one on each side to provide stability and to allow for measurements to be taken. Therefore, 4 corners x 2 batter boards per corner = 8 batter boards total.

Question 3

A ____ is a point of designated elevation that is accessible at all times during the construction.
A) target
B) baseline
C) reference
D) benchmark

Accepted Answer

A benchmark is a point of designated elevation that serves as a reference for all other elevations in the construction project. It must be accessible at all times during the construction process.

Question 4

The compensator in an automatic level uses ____ to maintain a true level line of sight.
A) gravity
B) electricity
C) magnetism
D) air pressure

Accepted Answer

The compensator in an automatic level uses gravity to maintain a true level line of sight.

Question 5

After leveling a transit-level over the point of an angle, called its ____, loosen the horizontal clamp screw.
A) measure
B) vertex
C) height
D) base

Accepted Answer

The vertex is the point of the angle, which is where the transit-level should be leveled over. Loosening the horizontal clamp screw allows the transit-level to be rotated to measure the angle. The other options (measure, height, base) are not directly relevant to this step in the process.

Question 6

The vertical cross hair of a telescope is helpful to measure vertical angles with a builders level.

Accepted Answer

The vertical crosshair in a telescope is used for alignment or aiming purposes, not for measuring vertical angles. A builder's level primarily measures horizontal angles and levels, not vertical angles.

Question 7

Rotating leveling screws of a transit is best done by moving thumbs toward or away from each other.

Accepted Answer

To rotate leveling screws of a transit, move thumbs toward or away from each other in a twisting motion. This is the best way to ensure that the screws are adjusted evenly and the instrument is level.

Question 8

The strings of a set of batter boards represent the edge of the excavation.

Accepted Answer

The answer of The strings of a set of batter...

Question 9

If a carpenter were to build a dock on a lake with posts, he/she could measure from the surface of the water to determine level.

Accepted Answer

Yes, measuring from the surface of the water is a common method of determining level when building a dock with posts.

Question 10

Elevations are best measured using a _____.
A) carpenter's level
B) tape measure
C) builder's level
D) elevator

Accepted Answer

Elevations are best measured using a builder's level. This tool allows for precise leveling and measuring of vertical distances.

Question 11

Dry buildings are easier to heat than damp ones.

Accepted Answer

Dry buildings have less moisture which means they have less thermal mass to heat up. Damp buildings, on the other hand, have higher thermal mass due to the water content, which makes them harder to heat.

Question 12

During the excavation of a foundation, all batter boards are removed.

Accepted Answer

Batter boards are not removed during the excavation of a foundation; they are used to mark the layout of the foundation and remain in place to guide the excavation and construction process.

Question 13

To detect a laser beam, a battery powered electronic sensor target, also called a receiver or ____, is attached to the leveling rod or stick.
A) detector
B) transistor
C) interceptor
D) sink

Accepted Answer

The term commonly used to describe an electronic device that is used to detect a laser beam is a detector. Therefore, choice A is the best option for the blank in the sentence. The other choices do not accurately describe a device that is used for this purpose.

Question 14

If building length is 40'-6" and the width is 31' -9", then the diagonal is ____.
A) 51'- 5 3/8"
B) 51'- 5 9/16
C) 51'- 7 3/8
D) 51'- 7 5/8

Accepted Answer

To find the diagonal of the building, we use the Pythagorean Theorem which states that the sum of the squares of the two sides of a right triangle (in this case, the length and width) is equal to the square of the hypotenuse (diagonal).

Using the formula, we get:

diagonal^2 = length^2 + width^2
diagonal^2 = (40.5)^2 + (31.75)^2
diagonal^2 = 1640.25 + 1008.5625
diagonal^2 = 2648.8125
diagonal = √2648.8125
diagonal = 51.57887

Rounding to the nearest 1/16" gives us:

Answer: B
 The diagonal is 51'- 5 9/16".

Question 15

If a horizontal beam is straight then it is also level

Accepted Answer

The answer of If a horizontal beam is straight then...

Question 16

The ____ level consists of a telescope to which a spirit level is mounted.
A) water
B) builder's
C) contractor's
D) carpenter's hand

Accepted Answer

The builder's level is commonly used in construction to ensure that a surface or structure is level or at a precise angle. It typically consists of a telescope to which a spirit level is mounted. Water level is another type of level that uses water in a tube to determine a level surface, while contractor's level and carpenter's hand level are other types of specialty levels used in construction and woodworking, respectively.

Question 17

Any line whose points are the same distance below or above an optical level's line of sight is also level.

Accepted Answer

This is the definition of a level line according to surveying and engineering principles.

Question 18

Measurements for building layout should follow the slope of the site.

Accepted Answer

Measurements for building layout should be taken horizontally, not following the slope of the site, to ensure accuracy and consistency in the dimensions.

Question 19

Batter boards consist of horizontal members called ____.
A) stakes
B) plumb bobs
C) tapes
D) ledgers

Accepted Answer

Batter boards typically consist of two vertical stakes set outside of the corners of the planned building foundation, and then two or more horizontal ledgers are attached to them to create a frame.

Question 20

A(n) ____ is a device that releases a narrow beam of light.
A) oscilloscope
B) telescope
C) laser
D) lab scope

Accepted Answer

A laser is a device that emits a narrow beam of light through the process of stimulated emission. Lasers have a variety of applications, including in medicine, communication, and manufacturing. Oscilloscopes and lab scopes are electronic test equipment used to measure and display electrical signals, while a telescope is used to observe objects in space.
