Re: How to apply for Engineering Services Examination?

Union Public Service commission conducts Engineering Services Examination for recruitment to the posts of Civil Engineering, Mechanical Engineering, Electrical Engineering, and Electronics & Telecommunication Engineering.

Important dates:
Opening Date for Registration: 22 March 2014
Closing Date for Registration: 21 April 2014
Date of Examination: 20 June 2014

As you can see that all dates are over, so you can not fill the application form now, generally the application form are made available at the official website of the UPSC and students need to fill it online.

Eligibility:
The applicant should have completed engineering with good academic record from any recognized university of India.

Age limit:
Between 21 to 30 Years. A relaxation in the upper age limit is available as per government norms.

Application Fee:
Rs. 200/- (SC/ ST/ PH/ Female Candidates are exempted)

Engineering Services Exam paper

3. (a) Designed a closed coiled helical spring to have spring index of 8. Axial defelction in spring is not to exceed 100 mm under an axial load of 2600 N and shear strees developed in spring is not to exceed 300 N/mm2 . Steel wires are available in diameters of 10, 11, 12, 13, 14 mm (in steps of 1mm). Determine most suitable wire diameter, mean coil diameter and number of coils in spring.

Given G = 84000N/mm2 . 10

(b) A two-cylinder uncoupled locomotive has inside cylinders 70 cm apart, the cranks are at right angles and are each 0.3 m long. The mass of revolving parts per cylinder is 160 kg and the mass of reciprocating parts per cylinder is 180 kg. The whole of the revolving and two-thirds of the reciprocating parts are to be balanced and the balance masses are to be placed in the planes of rotation of the driving wheels at a radius of 80 cm. The driving wheels are 2 m diameter and 1.5 m part.

Find the magnitude and position of the balance masses. The driving crank speed is 300 r.p.m. 15

(c) Draw a neat sketch of a cotter joint and show how its various elements are likely to fail under tensile loading. Give one engineering application of this joint. 5+4+1

(d) What is Bauschingers's effect ? Make a neat sketch of strees-strain diagram and explain how yield strength in compression is reduced than the yield strength in tension. 5
2. (a) An engine fitted with a single jet carburettor having a jet diameter of 1.25 mm has a fuel consumption of 6 kg/hr. The specific gravity of fuel is 0.7. The level of fuel in the float chamber is 5mm below the top of the jet when the engine is not running. Ambient conditions are 1 bar and 17°C. The fuel jet diameter is 0.6 mm. The discharge coefficient of air is 0.85. Air-fuel ration is 15. Determine the critical velocityof flow at throat and the throat diameter. Exprexx the pressure at throat in mm of water column. Neglect compressibility effect. Assume discharge coefficient of fuel flow is 0.60. 15

(b) Find the percentage increase in the efficiency of a Diesel Cycle having a compression ratio 'r' of 16 and cut off ratio 'r' is 10% of the swept volume, if Cv decrease by 2%. Take Cv← 0.717 kJ/kg °K and γ← 1.4. 15

(c) Explain the knocking phenomenon in a CI engine. Compare it with that of SI engines. Discuss the effect of operating variables on delay period and diesel knock. 10
