Answer (D)

Q 4. If y = 5x2+ 3, then the tangent at x = 0, y = 3

(A) passes through x = 0, y = 0 

(B) has a slope of +1

(C) is parallel to the x-axis

 (D) has a slope of −1

Answer-(C)

Notes:-
y = 5x2+ 3

y’= 10x  (slope)

So, at x=0, y’=0

Let equation of tangent be y=mx+c   (m = slope y’ & c = y intercept)

at x = 0, y = 3, c=3

So, the equation of tangent y=(0)x + 3

y = 3 which is parallel to x-axis.

Q 5. A foundry has a fixed daily cost of Rs 50,000 whenever it operates and a variable cost of Rs 800Q, where Q is the daily production in tonnes. What is the cost of production in Rs per tonne for a daily production of 100 tonnes?

Answer-(1300)
Notes:-
Total cost = 50000 + 800 x 100 = 130000 for 100 tonnes

So, the cost of production in Rs per tone is (130000/100) = 1300Q.

Q 8. The smallest angle of a triangle is equal to two thirds of the smallest angle of a quadrilateral. The ratio between the angles of the quadrilateral is 3:4:5:6. The largest angle of the triangle is twice its smallest angle. What is the sum, in degrees,  of  the  second largest angle of the triangle and the largest angle of the quadrilateral?

Answer-(180)

Notes:-
 Sum of angles of the quadrilateral = 3x + 4x + 5x + 6x = 360

So, x = 20

So,  The smallest angle of a triangle is = 2/3(3x) = 2/3(60) = 40

Also, The largest angle of the triangle is twice its smallest angle.

So, angles of the triangle are 40, 80, 60 (in degrees)

And, angles of the quadrilateral are 60, 80, 100, 120 (in degrees)

So, the sum, in degrees,  of  the  second largest angle of the triangle and the largest angle of the quadrilateral = 120+60 = 180

Q 9. One percent of the people of country X are taller than 6 ft. Two percent of the people of country Y are  taller than 6 ft. There are thrice as many people  in country X as in country Y. Taking both countries together, what is the percentage of people taller than 6 ft?(A) 3.0  (B) 2.5  (C) 1.5   (D) 1.25      

Answer (D)
Notes:-
Let population in county X is 300 & 100 in Y.

So, 3 people out of 300 in country X is taller than 6ft & 2 out of 100  people in country Y.

So, overall 5 people in 400 are taller than 6ft.

So, % = (5/400)x100 = 1.25

Noise Criteria for Rooms

Noise criteria (NC) curves can be used to evaluate existing situations by measuring sound levels at the loudest locations in rooms (preferably at user ear height).

They can also be used to specify the steady, or continuous background noise levels needed to help achieve satisfactory sound isolation, provided levels are 4 to 5 dB below the NC curve at both the low and high frequencies.

Each NC curve is defined by its sound pressure level over eight octave-band center frequencies shown on the following chart.

The table below presents recommended NC ranges for various indoor facilities.

• Concert halls, opera houses, broadcast, recording studios, large auditoriums, large churches and recital halls

Q 16. 

Among the following, the one that is NOT a land assembly technique is

(A)  Land Use Zoning   (B)  Accommodation Reservation

(C)  Town Planning Scheme  (D)  Transfer of Development Right 

Answer (A)

Notes:-

TDR is a regulatory strategy that harnesses private market forces to accomplish two smart growth objectives. First, open space is permanently protected for water supply, agricultural, habitat, recreational, or other purposes via the transfer of some or all of the development that would otherwise have occurred in these sensitive places to more suitable locations. Second, other locations, such as city and town centers or vacant and underutilized properties, become more vibrant and successful as the development potential from the protected resource areas is transferred to them. In essence, development rights are "transferred" from one district (the "sending district") to another (the "receiving district"). Communities using TDR are generally shifting development densities within the community to achieve both open space and economic goals without changing their overall development potential. While less common, TDR can also be used for preservation of historic resources.

 (C) Seismic & Geothermal Load        (D) Seismic & Wind Load

Answer (D)

Notes:-The Taipei 101, once the world's tallest building, sits a paltry 600 feet from a fault line.To counteract the forces working against it, architects installed a $4 million, 730-ton tune massed damper, which is a big ball 18 feet in diameter, made of 41 steel plates, and suspended by strong cables 3 1/2-inches think. It's said to cut down on the swaying of the building by almost 40%.

Q 19. 

 ‘Finger Plan’ concept of urban planning was initially adopted in

(A)  Canberra  (B) Paris 

(C)  Copenhagen  (D) Tokyo

Answer (C)

Notes:-

Copenhagen is famous for its urban planning concept which has pro-moted sustainable lifestyles and sustainable modes of mobility. The Finger Plan for Greater Copenhagen was introduced in 1947 when a group of town planners realized that Greater Copenhagen was beginning to spread uncontrollably.

Greater Copenhagen is a vast area consisting of 34 municipalities. The spreading of the area created difficulties for the public transport system, which was in danger of reaching its capacity. It was necessary to control the urban growth and develop a citywide network of railways and arterial roads. The idea of the plan was to concentrate the urban development of Greater Copenhagen in the urban “fingers” created around the railway network.

At the same time, the green wedges between the fingers would remain undeveloped. Greater Copenhagen resembles a hand where the city of Copenhagen covers the palm and five larger cities and their railway routes represent the fingers.

Here are some suggestions for how it could have worked:

1. build the railways with earth embankments as environmental noise barriers – probably with space for an express roadway in the same corridor
2. use the fingers as green infrastructure corridors for the urbanisation – growing the fingers as the urbanisation spreads
3. also use the fingers as utility corridors for: cycleways, habitat space, recreation space, a city forest, urban water runoff management, urban agriculture etc
4. extend ‘ribs’ of cycleway from rail stations into the urban areas between the green fingers
5. consider building above the railways and roads at some future date, to accommodate shops, offices and other commercial uses

Q 20. 

 The most important property of concrete in its fresh state is

(A)  Compressive  strength  (B) Tensile strength 

(C)  Elastic modulus  (D) Workability 

Answer (D)

NOtes:-

Workability is one of the physical parameters of concrete which affects the strength and durability as well as the cost of labor and appearance of the finished product. Concrete is said to be workable when it is easily placed and compacted homogeneously i.e without bleeding or Segregation. Unworkable concrete needs more work or effort to be compacted in place, also honeycombs &/or pockets may also be visible in finished concrete.

Definition of Workability

The property of fresh concrete which is indicated by the amount of useful internal work required to fully compact the concrete without bleeding or segregation in the finished product.

Factors affecting workability:

Water content in the concrete mix

Amount of cement & its Properties

Aggregate Grading (Size Distribution)

Nature of Aggregate Particles (Shape, Surface Texture, Porosity etc.)

Temperature of the concrete mix

Humidity of the environment

Mode of compaction

Method of placement of concrete

Method of transmission of concrete

Q. 26 – Q. 55 carry two marks each.

Q 26. 

A housing project is proposed to be designed in a plot of 2 hectare. Maximum permissible FAR is 2. The share of the numbers of dwelling units (DU) for MIG, LIG and EWS is 1:2:3 having sizes of 55, 35 and 25 sq.m respectively. The maximum number of DU which can be accommodated in the plot is  _______________

Answer (1200)

Notes:-

Plot area= 2hectare x 100 x 100 = 2 x 100 x 100 sq.m

Buildable area with 2 FAR = 2 x (2 x 100 x 100) sq.m

Total no of dwelling units = 1x + 2x + 3x = 6x

Area assigned for all MIG = (1x) X (55)sq. m

Area assigned for all LIG = (2x) X (35)sq. m

Area assigned for all EWS = (3x) X (25)sq. m

So,  [(1x) X (55)] + [(2x) X (35)] +[(2x) X (35)] = 2 x (2 x 100 x 100) sq.m

So, 200x = 40000

So, x =200

The maximum number of = 1x + 2x + 3x = 6x =1200

Q 30. 

 A neighborhood has 250 units of 80 sq.m each and 200 units of 100 sq.m each.  If the mandatory parking requirement is one per 100 sq.m of built space  then,  the total area(sq.m)  required for parking considering 30 percent additional area for circulation is  ________________

Answer (7150)

Note:-

As per the National Building Code (NBC) one car parking area must not be less than 13.75 Sq. Mtr and one two wheeler parking area must not be less than 1.25 Sq. Mtr.

Total built space = 250x80 + 200x100 = 40000 sq.m

Required no. of car parking = 40000/100 = 400 cars

Area required for 400 cars = 400 x 13.75 =5500 sq.m

For 30% extra space for circulation = 30% of 5500 = 1650 sq.m

Total area = 7150 sq.m

Q 40. 

A single span simply supported reinforced concrete beam (250 mm wide and 480 mm effective depth) is subjected to a concentrated load of 120 kN at its mid-span. Neglecting self-weight of the beam, the nominal shear stress (MPa) at the support section is  ______________

Answer (0.5)

Notes:-

 Reaction at the end = 120/2 = 60kN

Shear stress = force/area = 60kN/0.25mx0.48m = 0.5 MPa

(1 MPa = 106Pa =106N/M2)

Q 41.

The optimistic time, the pessimistic time and the most likely time of a job are 6, 13 and 8 days respectively. The variance for this job is   _______________

Answer (1.36)

Notes:-

Expected time  =  ( Optimistic  +  4 x Most likely  +  Pessimistic ) / 6

he variance is given by:[ ( Pessimistic  -  Optimistic ) / 6 ]2 =[( 13-6)/6]2 = 1.36

Q 42. 

A refuse  collection  system  consisting of two  chutes  is to be provided in a 20 storied residential building with 2 flats/floor (average family size = 5) and with each chute serving one flat on each floor. Average quantity of refuse and its density are 880 g/person/day and 240 kg/m3 respectively. If the cleaning interval is two days, then the minimum size of the refuse container (litre) at the bottom of each chute is _______________

Answer (733)

Total no. of person in the building = 2x5x20 = 200

No. person serving person chute = 200/2 = 100

Average quantity of refuse collected in 2 days in one chute = 2x0.88kgx100 = 176kg

So, volume of the chute = mass/density = 176/240 = 0.733m3 = 733L

Answer (D)

NOtes:-

• Caryatids are female figures serving as supports. The most likely derivation of their name is from the young women of Sparta who danced every year in honour of Artemis Karyatis ('Artemis of the Walnut Tree'). This is one of six caryatids that held up the roof of the temple on the Acropolis known as the Erechtheion. A caryatid is a sculpted female figure serving as an architectural support taking the place of a column or a pillar supporting an entablature on her head. The Greek term karyatides literally means "maidens of Karyai", an ancient town of Peloponnese.

• The hypocaust is one of the most ancient forms of an HVAC system.  Like many great innovations, it originated with the Romans over 2000 years ago

Q 45.

  In a dance hall the indoor and outdoor  temperatures are 28°C and 18°C respectively. There is an internal heat gain of 5 kW and the specific heat of air (on volume basis) is 1300 J/m3 °C, then the necessary cross sectional area (m2) of a duct with an air velocity of 2 m/s required for cooling by ventilation is  ____________

Answer (0.19)

Notes:-

5kW= 5kJoule of heat energy is generated in 1 sec.

Let, cross section area = A

So, V, the quantity of air passed in 1 sec.= 2A

Heat energy content in V amount of air = (amount of air)x(specific heat)x(temperature difference)

= (2A)x(1300)x(10) = 2600A

This heat energy must be compensated by 5k Joule as  heat gain.

So, 2600A=5000

ð  A= 0.19
