Structural Analysis 1 Important questions CE6501 

Structural Analysis 1 Important questions CE6501 Regulation 2013 Anna University free download. CE6501 Important questions free pdf download Regulation 2013.

Sample Structural Analysis 1 Important questions CE6501:

1. Why is it necessary to compute deflections in structures?

Computation of deflection of structures is necessary for the following reasons:
a. If the deflection of a structure is more than the permissible, the structure will not look
aesthetic and will cause psychological upsetting of the occupants.
b. Exessive deflection may cause cracking in the materials attached to the structure. For
example, if the deflection of a floor beam is excessive, the floor finishes and partition
walls supported on the beam may get cracked and unserviceable.

2. What is meant by cambering technique in structures? (Structural Analysis 1 Important questions)

Cambering is a technique applied on site, in which a slight upward curve is made in the structure/beam during construction, so that it will straighten out and attain the straight shape during loading. This will considerably reduce the downward deflection that may occur at later
stages.

3. Name any four methods used for computation of deflections in structures.(Structural Analysis 1 Important questions)

• Double integration method
• Macaulay‟s method
• Conjugate beam method
• Moment area method
• Method of elastic weights
• Virtual work method- Dummy unit load method
• Strain energy method
• Williot Mohr diagram method

4. State the difference between strain energy method and unit load method in the determination of deflection of structures. (Structural Analysis 1 Important questions)

In strain energy method, an imaginary load P is applied at the point where the deflection is desired to be determined. P is equated to zero in the final step and the deflection is obtained. In unit load method, an unit load (instead of P) is applied at the point where the deflection is desired.

5. What are the assumptions made in the unit load method?

• The external & internal forces are in equilibrium.
• Supports are rigid and no movement is possible.
• The materials is strained well with in the elastic limit.

Surveying 1 Important Questions CE6304

Surveying 1 Important Questions REGULATION 2013 ANNA UNIVERSITY free download. CE6304 Important Questions free download. Surveying 1 Regulation 2013 pdf free

Sample Surveying 1 Important Questions:

1. Define Surveying. What are the fundamental p rinciples of surveying?

Surveying is an art of determining the relative positions of various points on, above or below the surface of the earth by means of direct or indirect measurement of distance, direction and elevation.

The principles of surveying are:
(i) Working from whole to part.
(ii)To locate a new station by at least two measurements (angular, linear) from fixed reference points.

2. What is the object or purpose of surveying?

The primary object of surveying is to prepare a plan or map to show the relative position of
the objects on the surface of the earth. It is also used to determine the areas, volumes and other related
quantities.

3. Name the different ways of classification of surveys. (Surveying 1 Important Questions)

a. Primary classification
(i). Plane surveying (ii). Geodetic surveying.
b.Secondary classification
(i). Based on instruments used (ii).Based on methods.
(iii). Based on object (iv). Based on nature of the field

5. Define the constructions of a diagonal scale.

For a given short length ( PQ=PR), draw a right angle triangle. Its base( PR) and height (PQ) are equal. A short length is divided into a number of parts by using the principle of similar triangles in which like sides are proportional. Thus, 1-1 represents 1/ 10 PQ9-9 represents 9/ 10 PQ

6. Define chain surveying. What is the fundamental principle of chain surveying? (Surveying 1 Important Questions)

Chain surveying is the type of surveying in which only linear measurements are made in the field. The main principle of chain surveying or chain triangulation is to provide a framework
consist of number of well-conditioned triangles or nearly equilateral triangles. It is used to find the area of the field.

7. What is a well-conditioned triangle? What is its specific advantage?

A triangle is said to be well- conditioned or well proportioned when it contains no angle smaller than 300 and no angle greater than 1200.The main principle of chain surveying is chain triangulation. It consists of frame work of triangles. To plot the network of triangles accurately, the triangles must be nearly equal to equilateral or well-conditioned. The distortion due to errors in measurement and plotting should be minimum.

Sample MECHANICS OF FLUIDS Important questions:

1. Define fluid mechanics.

It is the branch of science, which deals with the behavior of the fluids (liquids or
gases) at rest as well as in motion.

2. Define Mass Density.

Mass Density or Density is defined as ratio of mass of the fluid to its volume (V)
Density of water = 1 gm/cm3 or 1000 kg / m3.

3. Define Specific Weight.
It is the ratio between weight of a fluid to its volume.
g p g
Volume of fluid
Mass of fluid
Volume of fluid
Weight of fluid
Unit: N / m3

4. Define Viscosity.

Viscosity is defined as the property of fluid, which offers resistance to the movement of one layer of fluid over another adjacent layer of fluid.
When two layers move one over the other at different velocities, say u and u+ du, the viscosity together with relative velocity causes a shear stress acting between the fluid layers. The top layer causes a shear stress on the adjacent lower layer while the lower layer causes a shear stress on the adjacent top layer.
This shear stress is proportional to the rate of change of velocity.

5. Define Specific Gravity.
Specific gravity is the ratio of the weight density or density of a fluid to the weight density or density of standard fluid. It is also called as relative density. Unit : Dimension less. Denoted as: ‘S’

Software Architectures Important Questions IT6602

Software Architectures Important Questions IT6602 Regulation 2013 Anna University free download. IT6602 Important Questions Regulation 2013 pdf free download.

Sample Software Architectures Important Questions:

1. What is software architecture?

The software architecture of a program or computing system is the structure or structures of the system, which comprise software elements, the externally visible properties of those elements,
and the relationships among them.”

2. What is architectural pattern?

An architectural pattern is a description of element and relation types together with a set of constraints on how they may be used.

3. Compare System Architecture and Software Architecture.

 Software architecture focuses on the implementation that will solve a specific problem.
 Systems architecture focuses on the underlying servers (physical or virtual) and server software (web servers, database et cetera) that the software will utilize. Systems architecture is largely focused on scaling with high availability, fault tolerance and
redundancy to avoid data loss.

4. What is reference model?

A reference model is a division of functionality together with data flow between the pieces. A reference model is a standard decomposition of a known problem into parts that cooperatively solve the problem.

5. What is reference architecture?

A reference architecture is a reference model mapped onto software elements (that cooperatively implement the functionality defined in the reference model) and the data flows between them.
Whereas a reference model divides the functionality, A reference architecture is the mapping of that functionality onto a system decomposition.

6. Why is software architecture important?

 Architecture is the vehicle for stakeholder communication
 Architecture manifests the earliest set of design decisions
 Architecture as a transferable, re-usable model
These are the reasons for the importance of software architecture from the technical perspective.

2. What is meant by Turing test?

To conduct this test we need two people and one machine. One person will be an interrogator (i.e.) questioner, will be asking questions to one person and one machine.

Three of them will be in a separate room.
Interrogator knows them just as A and B. so it has to identify which is the person and machine.

The goal of the machine is to make Interrogator believe that it is the person’s answer.

If machine succeeds by fooling Interrogator, the machine acts like a human.

Programming a computer to pass Turing test is very difficult.
