32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Young's Modulus

Ratio of tensile or compressive stress to the corresponding strain within the elastic limit; a measure of a material's stiffness, denoted E and expressed in pascals or N/mm².

Section Modulus

Geometric property equal to the moment of inertia divided by the distance from the neutral axis to the extreme fibre; for a rectangle it equals bd²/6.

Slump Test

Workability test for fresh concrete using a standard cone; the vertical fall of the concrete after the cone is removed indicates consistency and ease of placing.

Transformer EMF Equation

The induced RMS voltage in a winding equals 4.44 times frequency times turns times peak flux; it links winding design to supply frequency and core flux.

Four-Stroke Cycle

Engine cycle of intake, compression, power and exhaust strokes completed in two crankshaft revolutions; the camshaft therefore turns at half the crankshaft speed.

Three-Phase Power

In a balanced three-phase circuit, active power equals √3 times line voltage times line current times power factor, assuming sinusoidal supply and balanced loading.

CHSL Tier I Pattern

Computer-based test with four sections of 25 questions each: General Intelligence, General Awareness, Quantitative Aptitude and English Language, totalling 100 questions.

Successive Percentage Change

A rise of a per cent followed by b per cent gives a net change of a + b + ab/100 per cent; use negative signs for decreases.

Compound Interest Formula

Amount equals principal multiplied by (1 + rate/100) raised to the number of years; compound interest is the amount minus the principal.

CHSL Negative Marking

In Tier I, each wrong answer deducts 0.50 mark from the total; questions left unattempted attract no deduction.

Typing Test Norms

Skill test usually requires about 35 words per minute in English or 30 words per minute in Hindi, with marks adjusted for typing errors.

Ratio Chaining

To combine a:b and b:c, equalise the common term by cross-multiplication of the ratios, giving a single three-term ratio such as 15:20:24.

GD Constable Paper Pattern

Eighty objective questions of one mark each across reasoning, general knowledge, elementary mathematics and English or Hindi, completed in sixty minutes.

GD Negative Marking

Each incorrect response in the Constable GD computer-based examination deducts one quarter of a mark, while unattempted questions carry no penalty.

Physical Efficiency Test

Qualifying physical test with notified running and jump events; male candidates typically run 5 km and female candidates 1.6 km within prescribed times.

Physical Standard Test

Measurement of height, chest and weight against regional and category-wise norms; candidates failing the notified standards are disqualified from the recruitment.

Direction Sense Reasoning

Technique of tracing movement on paper using cardinal directions and turning angles to determine final distance or facing direction from the starting point.

Idiomatic Translation

Rendering a source-language idiom by a target-language idiom of equivalent meaning and register, rather than a literal word-for-word substitution.

Register in Translation

The level of formality and specialist vocabulary appropriate to the text type; official documents demand formal, impersonal and consistent terminology in both languages.

Bilingual Glossary Use

Applying the standard administrative glossary so that terms such as Comptroller and Auditor General are rendered identically throughout the translated text.

Transliteration

Writing a source-language term in the target script when no accepted equivalent exists, often retaining the original term in brackets for clarity.

Essay Assessment Criteria

Evaluation of a Hindi or English essay on relevance to the topic, logical structure, coherence, grammatical accuracy and appropriateness of vocabulary and style.

SI Paper I Sections

Computer-based paper covering General Intelligence and Reasoning, General Knowledge and General Awareness, Quantitative Aptitude, and English Comprehension, with negative marking.

SI Physical Endurance Test

Qualifying event sequence including a long-distance run plus long jump and high jump, with separate norms for male and female candidates as notified.

English Comprehension

Section testing reading comprehension, grammar, vocabulary such as synonyms and antonyms, sentence correction and idioms in the SI and CGL examinations.

Selection Post Qualification Levels

Selection Posts are grouped by required qualification: Matriculation, Higher Secondary, and Graduation and above, each with its own paper pattern and marking.

Selection Post CBT Parts

Computer-based test with General Intelligence, General Awareness and Quantitative Aptitude sections; question counts and marking differ by qualification level.

Post-Specific Skill Test

Typing or computer proficiency test administered only for posts whose notified specification requires it; qualifying in the skill test is essential for selection.

CGL Tier I Pattern

Four sections of 25 questions each in reasoning, general awareness, quantitative aptitude and English comprehension, totalling 100 marks in 60 minutes.

CGL Tier II Modules

Separate computer-based modules for mathematical abilities, reasoning, English, general awareness and computer knowledge, with sectional qualifying cut-offs.

Steno Skill Test

Dictation of 10 minutes at 100 words per minute followed by computer transcription in 40 minutes for English or 55 minutes for Hindi.

Steno Objective Pattern

Computer-based test of reasoning and general awareness at 50 questions each, plus English language and comprehension at 100 questions, with negative marking.
