1.) A line joining the points of highest elevation of water in a series of vertical open pipes rising
from a pipeline in which water flows under pressure is referred to as - ANSWER b. hydraulic
gradient
2.) According to ASTM D2487-17, particles of rock that will pass a 3-in (75 mm) sieve and be
retained on a No. 4 (4.75 mm) US standard sieve is called - ANSWER c. gravel
3.) NSCP 302.2 Cuts: Unless otherwise recommended in the approved geotechnical engineering
report or engineering report, cuts shall conform to the provisions of this section. In the absence
of an approved geotechnical engineering report, these provisions may be waived for cuts
________ meters or less in height, involving intact rock or hard soil, that are not intended to
support structures. - ANSWER b. 3
4.) NSCP 302.4 Fills: Unless otherwise recommended in the approved geotechnical engineering
report, fills shall conform to the provisions of this section. In the absence of an approved
geotechnical engineering report or engineering report, these provisions may be waived for
minor fills (H ≤ ________ m) not intended to support structures. - ANSWER d. 2
5.) NSCP 302.4.5 Slopes: The slope of cut surfaces shall be no steeper than is safe for the
intended use and shall be no steeper than 1 unit vertical in ________ units horizontal unless
substantiating data justifying steeper slopes are submitted and approved. - ANSWER c. 2
6.) NSCP 302.4.4 Compaction: All fills shall be compacted in litis not exceeding ________ cm in
thickness to a minimum of 90 percent of maximum density as determined by ASTM Standard D-
1557. - ANSWER a. 20
, 7.) The elastic tendency of liquids which makes them acquire the least surface area possible. It is
responsible, for example, when an object or insect such as mosquitoes that is denser than water
is able to float or run along the water surface. - ANSWER a. surface tension
8.) A pressure surge or wave caused when a fluid in motion is forced to stop or change direction
suddenly (momentum change) is referred to in hydraulics as - ANSWER d. water hammer
9.) If the ground water table in a soil formation rises as a resulting of flooding, the bearing
capacity of the soil - ANSWER c. decreases
10.) One of the following foundation conditions does not affect the bearing capacity of the
supporting soil. - ANSWER c. load imposed onto the soil
11.) What is the most used property in soil mechanics - ANSWER a. void ratio

boundary line than one fifth of the vertical height of cut with a minimum of 0.6 m and a
maximum of ________.The setback may need to be increased for any required interceptor
drains. - ANSWER a. 3 m

boundary line than one half the height of the slope with a minimum of 0.6 m and a maximum of
________. - ANSWER d. 6 m
