Q1 | Which of the following is the type of permanent joining process?
  • welding
  • soldering
  • both welding and soldering
  • none of the mentioned
Answer: both welding and soldering
Explaination:
in welding and soldering, once the join has made, we have to break the joint to get different part. so, both welding and soldering are known as permanent joining process.
Q2 | Which of the following is the type of temporary joining process?
  • brazing
  • mechanical joining
  • both brazing and mechanical joining
  • none of the mentioned
Answer: mechanical joining
Explaination:
brazing is the one type of permanent joining process and mechanical joining is the one type of temporary joining process because we can remove the joint with the help of equipments like some type of bolts and so on. breaking of joint is not necessary in this case.

  • casting process
  • joining process
  • forming and shaping process
Answer: machining process
Explaination:
in machining process, some raw material is wasted in or in order to perform different operations like drilling, turning etc.
Q4 | Which of the following is included in machining process?
  • extrusion
  • soldering
  • drilling
  • coating
Answer: drilling
Explaination:
drilling is included in machining process. for drilling, the drill is rotated with a downward pressure causing the tool to penetrate into the material.
Q5 | With the use of Jigs and fixture rate of production will
  • increase
  • decrease
  • remains same
  • jigs are not used in any production process
Answer: increase
Explaination:
total production increase with the use of jigs and fixture. jigs are holding device and fixture are generally used for the bigger work piece.

Answer: true
Explaination:
accuracy of parts increases by use of jigs and fixture. jigs are holding device and fixture are generally used for the bigger work piece.
Q7 | Jigs And fixture are used to provide interchangeability.
  • true
  • false
Answer: true
Explaination:
interchangeability of parts increases by use of jigs and fixture. jigs are holding device and fixture are generally used for the bigger work piece.
Q8 | With the use of Jigs and fixture
  • labour cost decreases
  • labour cost increases
  • none of the mentioned
Answer: labour cost decreases
Explaination:
less skilled labour required. interchangeability of parts increases by use of jigs and fixture. jigs and fixture increases accuracy. jigs are holding device and fixture are generally used for bigger work piece.
Q9 | Which of the following is not correct about fixture?
  • it is used to hold the work
  • it is used to position the work the work
  • it assures high accuracy of parts
  • it is used to guide the cutting tool
Answer: it is used to guide the cutting tool
Explaination:
fixture do not guide cutting tool. jigs and fixture increases accuracy. jigs are holding device and fixture are generally used for bigger work piece.
Q10 | Which of the following is not correct about jig?
  • it is used to hold the work
  • it is used to position the work the work
  • it is used to guide the cutting tool
  • none of the mentioned
Answer: none of the mentioned
Explaination:
all of the mentioned are correct about jigs. jigs and fixture increases accuracy. jigs are holding device and fixture are generally used for bigger work piece.
Q11 | In which of the following operation jigs are preferred over fixture?
  • drilling
  • turning
  • milling
  • grinding
Answer: drilling
Explaination:
jigs and fixture increases accuracy. jigs are holding device and fixture are generally used for bigger work piece. jigs are preferred over fixture in drilling because they also help in guidance of tool.
Q12 | Number of degree of freedom of a workpiece in space is equal to
  • 10
  • 12
  • 14
  • 16
Answer: 12
Explaination:
work piece has 16 degree of freedom. it can have 16 different movements.
Q13 | Land use, transportation and road network plans are                      
  • inter linked
  • intra linked
  • not linked
  • depends on the network
Answer: inter linked
Explaination:
land use, transportation and road network plans are inter linked to each other and they are inseparable.
Q14 | The first stage in the function of traffic engineering department is?
  • planning and design
  • collection of data
  • investigations
  • finance
Answer: collection of data
Explaination:
the first stage in the function of the traffic engineering department is a collection of data followed by analysis and design.
Q15 | Traffic forecast is not influenced by
  • gdp
  • industrial output
  • population
  • weather
Answer: weather
Explaination:
weather cannot influence the traffic forecast, as it is not related to traffic engineering, the remaining directly or indirectly are related to the traffic.
Q16 | Demographic factors do not include
  • gdp
  • population in urban cities
  • population in rural areas
  • overall population
Answer: gdp
Explaination:
demographic factors include
Q17 | The NHDP are being undertaken by private companies on the basis of                      
  • profit
  • revenue
  • bot
  • commission basis
Answer: bot
Explaination:
in india mostly private and govt. sectors follow bot which means build operate transfer, it is built by a private firm and later transferred to govt.

Answer: price of vehicles decreases
Answer: price of vehicles decreases
Explaination:
the traffic increases if the prices of vehicle decreases, price of fuel may increase and decrease, but if the price of the vehicle decreases then the traffic increases.

Answer: geometric method
Explaination:
the population forecast is calculated by
Q20 | The process of working out the cost per unit of each item is known as                    
  • work
  • sheet
  • data
  • analysis
Answer: data
Explaination:
the preparation of a detailed estimate comprises of working out quantities of different items of work and then determining the cost of each item. the

  • specific data record
Answer: standard data book
Explaination:
while fixing rate per unit of an item, the quantity of materials and labour needed for one unit of an item are strictly per the standard data book. however, the rates of labour and materials are obtained from the current standard scheduled of rates.
Q22 | In the case of works which require some special types of equipment, an amount of

  • 16-20
Answer: 1-2
Explaination:
in the case of works that require some special types of equipment, an amount of 1-2 percent of the estimated cost is given. while preparing a detailed estimate, it is also important to select a suitable site of work to reduce damage during the loading and unloading of materials.

  • unit base method
  • plinth area method
  • cylindrical base method
Answer: cylindrical base method
Explaination:
there are various methods used for preparing approximate estimates. these are the plinth area method, unit base method
Q24 | In the plinth area method, the cost of construction is computed by the multiplication of
