Here I am providing the Mechanical Engineering Syllabus/pattern of NPCIL exam which you are looking for . The duration of the Written Test will be of 2 hours and will be of 100 marks. The Written Test will consists of two parts (I) Management & General Aptitude Test (English Language, Quantitative Aptitude, Logical Reasoning, Data Interpretation, Analytical Ability) for 50 marks and Functional Knowledge Test (comprise of questions related to relevant professional qualification) for 50 Marks. The questions will be of Objective type. Each objective question is followed by answers serially numbered as A, B, C, and D. NCPIL Mechanical Question Paper During the execution of a CNC part program block NO20 GO2 X45.0 Y25.0 R5.0 the type of tool motion will be A) circular Interpolation — clockwise B) circular Interpolation — counterclockwise C) linear Interpolation D) rapid feed Answer : (A) In an interchangeable assembly, shafts of size 25.000+0.040mm mate with holes of size 25.000+0.020 mm.

The exponent n in Taylor A) 1/8 B) 1/4 C) 1/3 D) 1/2 Answer : (C) In PERT analysis a critical activity has A) maximum Float B) zero Float C) maximum Cost D) minimum Cost Answer : (B) Environment friendly refrigerant R134a is used in the new generation domestic refrigerators. Its chemical formula is A) CH C1 F2 B) C2 C13 F3 C) C2 C12 F4 D) C2 H2 F4 Answer : (D) Which of the following statements is INCORRECT? (A) Grashof’s rule states that for a planar crank-rocker four bar mechanism, the sum of the shortest and longest link lengths cannot be less than the sum of the remaining two link lengths. (B) Inversions of a mechanism are created by fixing different links one at a time. (C) Geneva mechanism is an intermittent motion device (D) Gruebler’s criterion assumes mobility of a planar mechanism to be one. For the stability of a floating body, under the influence of gravity alone, which of the following is TRUE? (A) Metacentre should be below centre of gravity (B) Metacentre should be above centre of gravity (C) Metacentre and centre of gravity must lie on the same horizontal line (D) Metacentre and centre of gravity must lie on the same vertical line The material property which depends only on the basic crystal structure is (A) fatigue strength (B) work hardening (C) fracture strength (D) elastic constant Little’s law is relationship between (A) stock level and lead time in an inventory system (B) waiting time and length of the queue in a queuing system (C) number of machines and job due dates in a scheduling problem (D) uncertainty in the activity time and project completion time Vehicle manufacturing assembly line is an example of (A) product layout (B) process layout (C) manual layout (D) fixed layout Simplex method of solving linear programming problem uses (A) all the points in the feasible region (B) only the corner points of the feasible region (C) intermediate points within the infeasible region (D) only the interior points in the feasible region. |
