B. Unstable
C. Stable and indeterminate
D. Stable and indeterminate to 2nd degree

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 9 - Question 120 (Ds = 3mre – 3J)

(=3×23 – 3 × 3 = 0)

Hence it is determinate and stable.

In general: If The structure is number of unknowns < number of equations Unstable number of unknowns = number of equations

Stable & Determinate number of unknowns > number of equations Indeterminate The procedure outlined above does not always work with regard to stability. An alternate method (the displaced shape method) of determining whether a structure is stable or unstable, and determinate or indeterminate is the following

If the displaced shape of the structure can be drawn so that no members deform, the structure is unstable.
If the displaced shape cannot be drawn without causing a member to deform, the structure is stable.

If removal of one constraint (a support force or a member force) causes the structure to be unstable (i.e. the structure can be displaced without deforming a member), then the original structure is stable and determinate. o If two or more constraints need to be removed to cause the structure to be unstable, the original structure is stable and indeterminate.

A. UU drainage conditions
B. CU drainage conditions
C. CD drainage condition
D. All of the above

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 9 - Question 129 1. Unconsolidated Undrained Test (UU)

Drainage is not permitted throughout the test. In the case of direct shear test drainage is not permitted during the application of both normal stress and shear stress. In the case of triaxial compression test drainage is not permitted during the application of both cell pressure and deviator stress. Since the test is conducted fast allowing no time for either consolidation of sample initially or dissipation of pore pressure in later stage, the test is also called quick test.

2. Consolidated Undrained Test (CU)

In this type of shear test the soil specimen is allowed to consolidate fully under initially applied stress and then sheared quickly without allowing dissipation of pore pressure. In the case of direct shear test the specimen is allowed to consolidate fully under applied normal stress and then sheared at high rate of strain to prevent dissipation of pore pressure during shearing. In the case of triaxial compression test the specimen is allowed to consolidate fully under the applied cell pressure and then the pore water outlet is closed and the specimen is subjected to increasing deviator stress at higher rate of strain.

3. Consolidated Drained Test (CD)

In this type of shear test drainage is allowed throughout the test. The specimen is allowed to consolidate fully under the applied initial stress and then sheared at low rate of strain giving sufficient time for the pore water to drain out at all stages. The test may continue for several hours to several days.

Bulking of sand occurs when the water content is,

A. 18 – 20%
B. 10 – 20%
C. 7 – 8%
D. 4 – 5%

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 9 - Question 154 The increase in volume due to bulking is between 20 to 30% for most sands at a 4 – 5% water content.

The increase in the volume of sand due to increase in moisture content is known as bulking of sand. A film of water is created around the sand particles which forces the particles to get a side from each other and thus the volume is increased.

The increase in moisture in sand increases the volume of sand. The volume increase in dry sand is known as the bulking if sand. Bulking of sand depends on the quantity of moisture in the sand and also the size of the particles. Five to eight percent of the increase in moisture in the sand can increase the volume of sand up to 20 to 40 percent. Again the finer the sand is more will be the increase in volume and increase in volume will be relatively less for coarser sand.

Backsight (BS) – short for "backsight reading", the first staff reading taken by the surveyor after the levelling instrument is set up and levelled. B.S is generally taken on the point of known reduced level as on the benchmark or a change point.

Hence, the correct option is (A)

Mock Test: SSC JE Civil Engineering (CE)- 9 - Question 159

The flow of water in a wash hand basin when it is being emptied through a central opening, is an example of-

A. Free vortex
B. Forced vortex
C. Rotational vortex
D. Rankine vortex

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 9 - Question 159 The flow of water in a wash hand basin when it is being emptied through a central opening, is an example of a free vortex.

Free vortex- Free and Forced Vortex flow with Examples states: When no external torque is required to rotate the fluid mass that type of flow is called free vortex flow.

Examples: Flow of liquid through a hole provided at the bottom of the container.

Hence, the correct option is (A)

Mock Test: SSC JE Civil Engineering (CE)- 9 - Question 160

A ridge canal is called a:

A. Watershed canal
B. Contour canal
C. Side slope canal
D. across the contours

Detailed Solution for Mock Test: SSC JE Civil Engineering (CE)- 9 - Question 160 RIDGE CANAL: The dividing ridgeline between the catchment areas of two streams (drains) is called the watershed or ridge canal. It is suitable for plain areas, where slopes are relatively flat and uniform. This type of alignment ensures gravity irrigation on both sides of the canal.

Hence, the correct option is (A)
