Q8 | For storeyed building plinth area estimate is not prepared for each storey separately.
  • true
  • false
Answer: false
Explaination:
for storeyed building plinth area estimate is prepared for each storey separately.
Q9 | is prepared on the basis of plinth area of building, the rate being deducted from the cost of similar building having similar specification, heights and construction, in the locality.
  • cube rate estimate
  • supplementary estimate
  • maintenance estimate
  • plinth area estimate
Answer: plinth area estimate
Explaination:
plinth area estimate is calculated by finding the plinth area of the building and multiplying by the plinth area rate. the plinth area should be calculated for the covered area by taking external dimension of the building at the floor level.
Q10 | In this method approx. total length of walls is found in running metre and this total length multiplied by the rate per running metre of wall gives a fairly accurate cost.
  • annual repair
  • item rate estimate
  • approximate quantity method estimate
  • cubical content estimate
Answer: approximate quantity method estimate
Explaination:
for this method the structure may be divided into two parts viz. foundation including plinth and superstructure.
Q11 | estimate is a detailed estimate and is prepared to maintain the structure or work in proper order and safe condition.
  • supplementary and revised estimate
  • maintenance estimate
  • item rate estimate
  • revised estimate
Answer: maintenance estimate
Explaination:
for building; this includes white washing, colour washing, painting, minor repairs etc. for road works the a.r. estimate provides for patch repairing, renewals, repair of culverts, etc.
Q12 | The term is used to denote a procedure of costing or valuing an item of work on the basis of actual labourers and materials required.
  • prime cost
  • hour-work
  • day-work
  • sub-work
Answer: day-work
Explaination:
certain items of work which cannot be measured as- a design in the plaster work, front architectural finish of a building, work under water, etc. are valued and paid by ‘day work’. in such cases the schedule of rates of materials and different classes of labourers likely to be engaged in th work should be included in the tender and in contract agreement.
Q13 | Shaping of metal by squeezing them in between two or more dies in order to obtain desire shape is done by?
  • forming
  • forging
  • welding
  • grinding
Answer: forging
Explaination:
forging is the term applied to a
Q14 | Which of the following is a type of forging?
  • open die
  • closed die
  • impression dies
  • hold dies
Answer: hold dies
Explaination:
there are basically three methods (or processes) to make a forged part,
Q15 | In which of the following forging metal is kept in the lower die?
  • open die
  • closed die
  • impression dies
  • hold dies
Answer: open die
Explaination:
when shaping a solid piece of metal by closed die forging, the die is initially open. the work piece is placed in the lower die half, and the top die is then brought down to engage with the work piece the
Q16 | In which of the forging process metal is kept in between a pair of dies and a gutter is provided in the lower die?
  • open die
  • closed die
  • impression dies
  • hold dies
Answer: closed die
Explaination:
in closed die forging process metal is kept in between a pair of dies and a gutter is provided in the lower die. in impression die forging process metal is kept in between a pair of dies and no gutter is provided in the lower die.
Q17 | The extra metal which settles down in the gutter is known as?
  • flash
  • slag
  • flux
  • barrelling
Answer: flash
Explaination:
in impression die forging, the die surfaces contain a shape that is given to the work piece during compression, thus restricting the metal flow significantly. there is some extra deformed material outside the die impression which is called as flash. this will be trimmed off later.
Q18 | In which of the following forging process no flash is formed?
  • open die
  • closed die
  • impression dies
  • hold dies
Answer: closed die
Explaination:
in flashless forging, the work piece is fully restricted within the die and no flash is produced. the amount of initial work piece used must be controlled accurately so that it matches the volume of the die cavity.
Q19 | Cogging, which is also called as drawing out, is basically?
  • open die forging operation
  • closed die forging operation
  • impression dies forging operation
  • hold die forging operation
Answer: open die forging operation
Explaination:
cogging is an open die forging process in which flat or slightly contoured die are employed to compress a work piece, reducing its thickness and increasing its length.
Q20 | In rolling operation, the roll rotates with surface velocity?
  • exceeding the speed of incoming metal
  • lower than the speed of incoming metal
  • equal to speed of the incoming metal
  • very higher than the speed of incoming metal
Answer: equal to speed of the incoming metal
Explaination:
the rolls rotate with a surface velocity exceeding the speed of the incoming metal, friction along the contact interface acts to propel the metal forward. the metal is squeezed and elongated and usually changed in cross section.
Q21 | A round billet made of 70-30 brass is extruded at a temperature of 675°C. The billet diameter is 125 mm, and the diameter of the extrusion is 50 mm. Calculate the extrusion force required.
  • 4 mn
  • 5 mn
  • 5.6 mn
  • none of the mentioned
Answer: 5.6 mn
Explaination:
the extrusion force is calculated using
Q22 | In which type of extrusion, a billet is placed in a chamber?
  • forward
  • indirect
  • hydrostatic
  • impact
Answer: forward
Explaination:
in forward extrusion, a billet is placed in a chamber and forced through a die opening by a hydraulically driven ram. the die opening may be round, or it may have various shapes, depending on the desired profile.
Q23 | In which type of extrusion, the die moves toward the unextruded billet?
  • forward
  • indirect
  • hydrostatic
  • impact
Answer: indirect
Explaination:
in indirect extrusion, (also called reverse, inverted, or backward extrusion), the die moves toward the unextruded billet. indirect extrusion has the advantage of having no billet-container friction, since there is no relative motion.
Q24 | In which type of extrusion, the billet is smaller in diameter than the chamber?
  • forward
  • indirect
  • hydrostatic
  • impact
Answer: hydrostatic
Explaination:
in hydrostatic extrusion, the billet is smaller in diameter than the chamber
Q25 | Scope of automation in foundry process is
