Re: Railway JE Recruitment exam Previous year Question Paper
Hi friend here I am giving you the Railway JE Recruitment exam Previous year Question Paper 1 Lissajous pattern shown in a double-beam cathode-ray oscilloscope screen for two sinusoidal voltages of equal magnitude and of the same frequency but of phase shift of 300 electrical is A circle A straight line at 45 0 in the first and third quadrant An ellipse in the first and third quadrant An ellipse in the second and fourth quadrant Ans : (c To increase the range of a voltmeter A low resistance in series is connected with the voltmeter A low resistance in parallel is connected with the voltmeter A high resistance in series is connected with the voltmeter A high resistance in parallel is connected with the voltmeter Ans : (c Question1. Time and progress chart of a construction is also known as Bar chart Gantt chart Modified milestone chart Any of the above Question2. Low turbidity of water is detected by Turbidity tube Jackson turbid meter Baylis turbid meter Hellipe turbid meter Question3. What is the pH value for neutral water? 1 7 10 14 Question4. Two steel parts at right angles are weided with fillet weld of 10 mm size. The throat thickness of the fillet weld should be? 7mm 10 mm 12 mm 5 mm Question5. In a moment resisting connection, the moment carrying capacity is provided by Tension in rivets Compression in rivets Shear in rivets Bearing strength in rivets Question6. A good brick when immersed in water bath for hours, should not observe more than 20% of its saturated weight 30% of its dry weight 10% of its saturated weight 15% of its dry weight Question7. Plaster of Paris can be obtained from the calcinations Lime stone gypsum dolomite bauxite Question8. Two equal angles, each being ISA 100 mm × 100 mm of thickness 10 mm, are placed back-to-back and connected to either side of a gusset plate through a single row of 16 mm diameter rivets in double shear. The effective areas of the connected and unconnected legs of each of these angles are 775mm2 and 950 mm2 respectively. If these angles are not tack-riveted, the net effective area of this pair of angles is 3650 mm2 3450 mm2 2899 mm2 3076 mm2 Question9. In a steel plate girder, the web plate is connected to the flange plates by fillet welding. The size of fillet welds is designed to safely resist. The bending stresses in the flanges The vertical shear force at the section The horizontal shear forces between the flanges and the web plate The forces causing buckling in the web Question10. Out of the two beams of the same material and same cross-sectional area, one is of circular cross-section and the other is of square cross-section. If each of these is subjected to bending moment of the same magnitude, then Both Sections Would Be Equally Strong Both Sections Would Be Equally Economical Square Section Would Be More Economical Than Circular Section Square Section Would Be Less Economical Than Circular Section Question11. The Muller-Breslau principle in structural analysis is used for Drawing Influence Line Diagram for Any Force Function Superimposition of Load Effects Writing Virtual Work Equation None of The Above Question12. In relation to the synchronous machines, which one of the following statements is false? In salient pole machines, the direct-axis synchronous reactance is greater than the quadrature-axis synchronous reactance The damper bars help the synchronous motor self start Short circuit ratio is the ratio of the field current required to produce the rated voltage on open circuit to the rated armature current The V-curve of a synchronous motor represents the variation in the armature current with field excitation, at a given output power. Answer : (C) Question13. A 800 kV transmission line is having per phase line inductance of 1.1 mH/km and per phase line capacitance of 11.68 nF/km. Ignoring the length of the line, its ideal power transfer capability in MW is? 1204 MW 1504 MW 2085 MW 2606 MW Answer : (C) Question14. High Voltage DC (HVDC) transmission is mainly used for Bulk power transmission over very long distances Inter-connecting two systems with the same nominal frequency Eliminating reactive power requirement in the operation Minimizing harmonics at the converter stations Answer : (A) Question15. Body effect in MOSFETs results in Increase in the value of trans conductance Change in the value of threshold voltage Decrease in the value of trans conductance Increase in the value of output resistance Question16. A 2-port network has parameters of ABCD. If all the impedences in the network are Doubled, then A and D are remain unchanged B is doubled and C is halved A, B, C and D are all Doubled A and D are doubled C and B remain unchanged A and D remain unchanged C is doubled and B is halved. Ans : (a
