Part 2: Engineering Drawing & Technical Concepts
- Solid cutting for medium line is?
A) 1mm
B) 0.2mm
C) 0.33mm
D) 0.55mm
Ans: A) 1mm
Explanation: In standard engineering drawing practices, thick solid lines (used for visible outlines and cutting planes) are typically drawn bolder, often around 1mm in thickness (or between 0.6mm to 1mm depending on paper size), to distinguish them clearly from thin dimension lines. - In Engineering Drawing normally ……… are used?
A) Vernier scale
B) Plain scale
C) Diagonal scale
D) B and C both
Ans: B) Plain scale
Explanation: For most general, basic engineering drafting applications, a plain scale (which represents two consecutive units, like mm and cm) is standardly used for its simplicity. Diagonal scales are used when higher precision (three units) is needed. - Representative fraction for full-size scale is?
A) Half
B) Equal to one
C) Less than one
D) More than one
Ans: B) Equal to one
Explanation: Representative Fraction (RF) = (Length of the drawing) / (Actual length of the object). When an object is drawn to its exact real-world dimensions (full-size), the ratio is 1:1, meaning RF = 1. - If a semicircle is rotated with respect to its radius, then it forms a?
A) Cube
B) Cylinder
C) Sphere
D) Cone
Ans: C) Sphere
Explanation: Geometrically, a sphere is known as a solid of revolution. When a 2D semicircle is rotated a full 360 degrees around its straight diametrical edge, it sweeps through 3D space to form a perfect sphere. - Isometric projection is ……….. to its isometric view of any object?
A) One and half times
B) Smaller
C) Equal
D) Bigger
Ans: B) Smaller
Explanation: An isometric projection is drawn using an isometric scale and is mathematically smaller (about 81.6% or roughly 0.82 times the actual length). An isometric view is drawn using true lengths, making the projection visually smaller than the view. - Threads of a bolt are?
A) Deep
B) Internal
C) External
D) Both
Ans: C) External
Explanation: Fasteners like bolts and screws feature threads on their outside surface, classifying them as external threads. Nuts, which mate with bolts, have internal threads. - The line at which the surface of two solids contacts is known as?
A) Firm line
B) Cutting Line
C) Line of intersection
D) Sectional Line
Ans: B) Cutting Line
Explanation: In drawing problems dealing with sections of solids, the imaginary plane that slices through the object is represented by a cutting plane line. (Note: “Line of intersection” is technically the geometric term, but in draftsmanship exams, a cutting plane yields this contact surface).
Part 3: Basic Electrical Knowledge
- Induction type instrument can be used in?
A) D.C. circuit only
B) A.C. circuit only
C) Both A.C. and D.C. circuit
D) None is correct
Ans: B) A.C. circuit only
Explanation: Induction instruments work on the principle of electromagnetic induction (creating torque via changing magnetic fluxes interacting with eddy currents), which requires a changing magnetic field. Therefore, they only function with Alternating Current (AC). - Among all wiring systems, the …… wiring system is the most common in today’s wiring?
A) Casing-capping
B) Cleat
C) Concealed conduit
D) Surface conduit
Ans: C) Concealed conduit
Explanation: Concealed conduit wiring (where PVC pipes are laid inside the walls and plaster) is the standard for modern residential and commercial buildings because it is highly safe, protects against fire, and maintains interior aesthetics. - Fuse is always placed on?
A) Neutral line
B) Phase line
C) On both the lines
D) On any line
Ans: B) Phase line
Explanation: A fuse or circuit breaker must always be connected in series with the live (phase) wire. If a fault occurs, the fuse blows and entirely disconnects the phase supply, ensuring the appliance is completely dead and safe to touch. - The commonly used wiring system in a building is?
A) Looping in system
B) Tree system
C) Distribution board system
D) Joint box system
Ans: C) Distribution board system
Explanation: The Distribution Board (DB) system is utilized in buildings because it divides the main electrical feed into subsidiary circuits. Each circuit is protected by an individual breaker, meaning a fault in one room won’t cause the whole building to lose power. - The body of an M.C.B. (Miniature Circuit Breaker) is made of?
A) Plastic alloy
B) Porcelain
C) Plastic
D) Bakelite
Ans: A) Plastic alloy
Explanation: The outer casing of an MCB is typically manufactured from molded fire-retardant plastic alloys or thermoplastics. These materials are excellent insulators and can withstand the heat generated during electrical tripping. - To test the transformer oil, the sample is always taken from the?
A) Conservator tank
B) Top of the tank
C) Bottom of the tank
D) Anywhere
Ans: C) Bottom of the tank
Explanation: Transformer oil is tested for its dielectric strength and purity. Since water, sludge, and solid impurities are heavier than the oil, they settle at the bottom. Taking the sample from the bottom provides the most accurate assessment of worst-case contamination.
Frequently Asked Questions (FAQs)
1. Are these questions enough to pass the RRB Exams?
No, these model questions are meant for practice and self-assessment. To pass the RRB exams, you need a comprehensive study plan covering the entire official syllabus, regular mock tests, and previous years’ question papers.
2. Is there negative marking in the RRB Centralised Exams?
Yes, most RRB examinations like NTPC, Group D, and ALP have a negative marking of 1/3rd of the marks allotted for each incorrect answer. It is highly advised not to guess blindly, which is why reading explanations to understand the core concept is so important.
3. How can I improve my technical score for RRB ALP & Technician?
Focus heavily on core concepts of basic engineering drawings, electrical circuits, and safety tools. Solving topic-wise technical MCQs, like those shared in parts 2 and 3 above, and understanding why an answer is correct will significantly improve your accuracy.
