RSMSSB JE Civil Mock Test - 5 - Question 11

Which of the following relationships represents the hydrological cycle?

Detailed Solution: Question 11

The hydrological cycle is also known as the water cycle, in this cycle water evaporates from the land and ocean however the precipitation goes back to the land surface. The three major processes in the hydrological cycle are precipitation, evaporation, and condensation.

And, Precipitation = Evaporation + Runoff

Additional Information There are four main parts to the water cycle: Evaporation, Convection, Precipitation, and Collection.

1) Evaporation

  • Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air.

2) Convection

  • Convection in the water cycle is when the air near the surface is heated, then rises taking heat with it. Water vapor in the air gets cold and changes back into liquid, forming clouds. This is called condensation.

3) Precipitation

  • Precipitation occurs when so much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet, or snow.

4) Collection/Storage

  • A lot of the Earth's water does not take part in the water cycle very often. Much of it is stored. The Earth stores water in a number of places. The ocean is the largest storage of water. Around 96% of the Earth's water is stored in the ocean.

RSMSSB JE Civil Mock Test - 5 - Question 12

The defects that are indicated by the curvature formed in the direction of length of timber is called

Detailed Solution: Question 12

Concepts:

The various types of defects in Timber are depicted below:

1. Knots:

These are the bases of branches or limbs which are broken or cut off from the tree. The portion from which the branch is removed receives nourishment from the stem for a pretty long time and it ultimately results in the formation of dark hard rings which are known as knots.

2. Rind galls:

The rind means bark and the gall indicates abnormal growth. Hence peculiarly curved swellings found on the body of a tree are known as the rind galls

3. Shakes:

These are cracks that partly or completely separate the fibers of the wood.

4. Bow:

This defect is indicated by the curvature formed in the direction of length of timber.

5. Case-Hardening:

The exposed surface of timber dries very rapidly. It therefore shrinks and is under compression. The interior surface which has not completely dried is under tension. This defect is known as the case-hardening and it usually occurs in timbers which are placed at the bottom during seasoning.

6. Check:

A check is a crack which separates fibers of wood. It does not extend from one end to the other.

7. Honey - Combing:

Due to stresses developed during drying, the various radial and circular cracks develop in the interior portion of timber. The timber thus assumes the honey-comb texture and the defect so developed is known as the honey-combing.

RSMSSB JE Civil Mock Test - 5 - Question 13

The contour interval should be

Detailed Solution: Question 13

Concept:

Contour:

Line joining points of the same elevation are called contour lines.

Contour Interval:

  • A contour interval is a vertical distance or difference in elevation between contour lines.
  • It is always kept the same or constant for a map.


The contour interval depends upon the following factors:

1. The scale of the map:

The contour interval normally varies inversely to the scale of the map i.e., if the scale of the map is large, the contour interval is considered to be small and vice versa.

2. Purpose of the map:

For a very important and detailed design, contour intervals should be kept small.

3. Nature of ground:

For flat ground, a small contour interval is chosen whereas, for undulating and broken ground, a greater contour interval is adopted.

4. Time & Cost:

If the contour interval is small, greater time and funds will be required in the field survey, in reduction, and in plotting the map. If the time and funds available are limited, the contour interval may be kept large.

5. Slope:

Contour interval ki directly proportional to the slope. Contour intervals for flat countries are generally small, e.g. 0.25 m, 0.5 m, 0.75 m, etc. Contour interval in hilly areas is generally greater, e.g. 5 m, 10 m, 15 m, etc

RSMSSB JE Civil Mock Test - 5 - Question 17

The continuity equation for steady incompressible flow is expressed in vector notations as

Detailed Solution: Question 17

  • The law of conservation of mass states that mass can neither be created nor be destroyed.
  • The rate at which mass enters the region = Rate at which mass leaves the region + Rate of accumulation of mass in the region
  • The above statement can be expressed analytically in terms of velocity and density field of flow and the resulting expression is known as the equation of continuity or the continuity equation.

Important Points

  • The continuity equation applies to all fluids, compressible and incompressible flow, Newtonian and non-Newtonian fluids.
  • It expresses the law of conservation of mass at each point in a fluid and must, therefore, be satisfied at every point in a flow field.
  • So, the continuity equation is connected with the conservation of mass and it can be applied to viscous/non-viscous, the compressibility of the fluid, or the steady/unsteady flow.

RSMSSB JE Civil Mock Test - 5 - Question 19

In a rear counterfort retaining wall, the main reinforcement is provided on the
A. bottom face in front counterfort
B. inclined face in front counterfort
C. bottom face in back counterfort
D. inclined face in back counterfort

Detailed Solution: Question 19

Concept:

A counterfort retaining wall is a cantilever wall with counterforts, or buttresses, attached to the inside face of the wall to further resist lateral thrust. The use of this counter fort is to reduce the shear force, and the bending moment in the vertical steam of the slab.

Design of counterfort retaining wall:

In a counterfort retaining wall, the vertical slab is designed as a continuous slab and the heel slab is designed as a continuous slab because this will reduce joint efficiency hence an extra margin is created. But this will increase the cost also.

Concept:

A counterfort retaining wall is a cantilever wall with counterforts, or buttresses, attached to the inside face of the wall to further resist lateral thrust.

  • In the counterfort retaining wall, the stem and the base and the base slab are tied together by counterforts, at suitable intervals
  • Because of the provision of counterforts, the vertical stem, as well as the heel slab, acts as a continuous slab, in contrast to the cantilevers of cantilever retaining wall
  • Counterforts are firmly attached to the face slab as well as the base slab; The earth pressure acting on the face slab is transferred to the counter forts which deflect as vertical cantilevers
  • The back of the rear counter forts comes in tension and their front face is under compression
  • Hence the inclined (back) face of rear counter forts should be provided with main reinforcement and in front counterforts, the tension develops at the bottom face so it is provided with main reinforcement
  • Counterfort retaining walls are economical for height over about 6m

∴ In a counterfort retaining wall, the main reinforcement is provided on the bottom face in front counterfort and inclined face in back counterfort.

RSMSSB JE Civil Mock Test - 5 - Question 20

For good bonding in brick masonry

Detailed Solution: Question 20

Concepts:

Brick Bonds is the interlacement of bricks when they laid immediately one below or above another. It is the method of arranging the bricks in a successive course so that, individual units are joined together and the vertical joints of successive courses do not rest in the same vertical line.

The following rules for getting a good brick bond should be adopted.

  1. The bricks should be uniform in size. The length of the brick should be twice the width plus one joint so that a uniform lap is obtained.
  2. A good bond is not possible if the lap is non-uniform. The amount of lap should be a minimum of 1/4 brick along the length of the wall and 1/2 brick across the thickness of the wall.
  3. In alternate courses, the centerline of the header should coincide with the centerline of the stretcher, in the course below or above it.
  4. The use of brickbats should be discouraged, except in special locations.
  5. The vertical joints in the alternate courses should be along the same pretend.
  6. It is preferable to provide every sixth course as a header course on both the side of the wall.
