Sample CE6605 Important questions :

1) What do you mean by time of concentration?

State its significance in sewage
design. (A/M-11)
 The period after which the entire area will start contributing to the runoff is called time of concentration.
(OR)
 It is defined as the longest time without unreasonable delay that will be required for a drop of water to flow from further point of drainage area.
 It indicates the time of flow, time of entry, exit and the run off times.

2) State the pollution control board norms for effluent discharge into streams? (A/M-11)

 To render sewage inoffensive.
 To save the aquatic life.
 Tom eliminate the danger of contamination of water supplies.
 The amount of treatment that should be given to the sewage.

3) List the factor influencing the fixing of design period? (A/M-11)

 Weather flow condition
 Rate of water supply
 Type of area served
 Population growth

6) State the necessity of waste water characterization? (M/J-12)

 It’s indicates the amount of heavy metals and synthesized organic compounds generated by industrial activities.
 As technological changes takes place in manufacturing. Changes also occur in the compounds discharged and the resulting waste water characteristics.
 Therefore waste water characterization on becomes a essential pats of an overall water quality management program.

CE6604 Important questions Railways Airports and Harbour Engineering

CE6604 Important questions Railways Airports and Harbour Engineering Regulation 2013 Anna University Free download. Railways Airports and Harbour Engineering Important questions free pdf download.

Sample CE6604 Important questions :

1. Define Permanent way?

The combination of rails, fitted on sleepers and resting on ballast and sub grade is called the Railway track or Permanent way.

2. Define Gauge?

The „Gauge‟ of a railway track is defined as the clear distance between inner or running faces of two track rails.

3. Define Rails?

The rails on the track can be considered as steel girders for the purpose of carrying axle loads. They are made of high carbon steel to withstand wear and tear.

4. What are the different types of rail sections?

1. Double headed rails (D.H.Rails)
2. Bull headed rails (B.H.Rails)
3. Flat footed rails (F.F.Rails)

5. What are the different types of rail joints?

1. Supported rail joints.
2. Suspended rail joints.
3. Bridge joints.
4. Base joints.
5. Welded joints.
6. Square joints.

6. Define Creep?

Creep is defined as the longitudinal movement of rails with respect to sleepers in a track.

7. Classify Sleepers?

1. Wooden sleepers
2. Metal sleepers
a) Cast iron sleepers
b) Steel sleepers
3. Concrete sleepers
a) Reinforced concrete sleepers
b) Prestressed concrete sleepers

8. What are the uses of Fish plates?

Fish plates are used in rail joints to maintain the continuity of the rails and to allow for any expansion or contraction of the rail caused by temperature variations. They maintain the correct alignment of the line both horizontally and vertically.

CE6603 important questions DESIGN OF STEEL STRUCTURES

CE6603 important questions DESIGN OF STEEL STRUCTURES Regulation 2013 Anna University free download. DESIGN OF STEEL STRUCTURES important questions free download.

Sample CE6603 important questions:

1. What are the various types of connections used for connecting the
structural members?
 Riveted connections
 Bolted connections
 Pin connections
 Welded connections

2. Define riveting.
Riveting is a method of joining two or more structural steel components by
inserting ductile metal pins, called rivet.

3. Define nominal diameter of rivet.
It is the diameter of the unheated rivet measured before driving. It is the
stated diameter of the rivet, available in the market.

4. Define gross diameter of rivet.
It is the diameter of the rivet in the hole, measured after driving. It is taken equal to the diameter of the rivet hole.

5. What is meant by pitch of rivet?
The pitch of the rivets is the distance between centres of two adjacent
rivets in a row.

6. Define gauge line.
It is the line of rivets, which is parallel to the direction of stress.

7. What is meant by gauge distance and edge distance?
Gauge distance is the perpendicular distance between two adjacent gauge lines. This is also called as back pitch. Edge distance is the distance of the edge of the member or the cover
plates from the centre of extreme rivet hole.

8. Define staggered pitch.
It is also called as alternate pitch or reeled pitch. The staggered pitch is defined as the distance measured along one rivet line from the centre of a rivet to the centre of the adjoining rivet on the adjacent parallel rivet line.

9. Define lap.
It is the distance normal to the joint between edges of the overlapping
plates in a lap joint or between the joint and the end of cover plates in a butt joint.

CE6602 Important questions STRUCTURAL ANALYSIS 2 

CE6602 Important questions STRUCTURAL ANALYSIS 2 Regulation 2013 Anna University free download. STRUCTURAL ANALYSIS 2 Important questions free download.

Sample CE6602 Important questions:

1. Whatis meantby indeterminatestructures?

Structures that do not satisfy the conditions of equilibrium are called indeterminate structure. These structures cannot be solved by ordinary analysis techniques.

2. What are the conditions of equilibrium?

The three conditions of equilibrium are the sum of horizontal forces, vertical forces and moments at any joint should be equal to zero.
i.e.ΣH=0;ΣV=0;ΣM=0

3. Differentiate between determinate and indeterminate structures.
Determinatestructurescanbesolvingusingconditionsofequilibriumalone(ΣH=0;ΣV=0;ΣM=0). No other conditions are required.
Indeterminatestructurescannotbesolvedusingconditionsofequilibriumbecause(ΣH≠0;ΣV≠0;ΣM≠0).Additional conditions are required for solving such structures. Usuallymatrixmethods areadopted.

4. Define degree of indeterminacy

(i). The excess number of reaction is that make a structure indeterminate is called degree of
indeterminacy,and is denoted by(i).Indeterminacy is also called degree of redundancy. Indeterminacy consists of internal and external in determinacies.
i =II+EIwhereII=internal indeterminacyand EI=external indeterminacy.

5. Define internal and external indeterminacies.
Internal indeterminacy (II) is the excess no of internal forces present in a member that make a structure in determinate.
External in determinacy (EI) is excess no of external reactions in the member that make the structure in determinate.
i =II+EI;
EI=r– e;wherer=no ofsupport reactions and e=equilibrium
conditions II=i –EI
e=3 (planeframes) ande=6 (spaceframes)

6. Write the formulae for degree of indeterminacy for:
(a)Two dimensional pin jointed truss(2D Truss)
i =(m+r)– 2j wherem=no ofmembers
r=no ofreactions j
=no ofjoints
(b)Two dimensional rigid frames/plane rigid frames (2DFrames)
i =(3m+r)– 3j wherem=no ofmembers
r=no of reactions j =no of joints
