SSC JE Syllabus
Mechanical Engineering

 SSC 2020 Syllabus – JE (Mechanical Engineering)  – Staff Selection Commission (SSC) conducts JE (Junior Engineering) Examination every year for recruitment of junior engineers (JEs) for different-different government departments. The recruitment of SSC JE is done in three branches of engineering – Electrical, Civil and Mechanical Engineering.

SSC Junior Engineering (SSC-JE) exam has two papers – Paper-I and Paper-II. Candidates appearing for SSC JE exam should be aware of SSC JE syllabus along with the important topics. In this article, we have provided detailed SSC JE Syllabus for Mechanical Engineering.

Paper-I – Syllabus

(1) General Intelligence & Reasoning :

The Syllabus for General Intelligence would include questions of both verbal and non-verbal type. The test may include questions on analogies, similarities, differences, space visualization, problem solving, analysis, judgment, decision making, visual memory, discrimination, observation, relationship concepts, arithmetical reasoning, verbal and figure classification, arithmetical number series, etc. The test will also include questions designed to test the candidate‟s abilities to deal with abstract ideas and symbols and their relationships, arithmetical computations and other analytical functions.

(2) General Awareness :

Questions will be aimed at testing the candidate‟s general awareness of the environment around him/ her and its application to society. Questions will also be designed to test knowledge of current events and of such matters of everyday observations and experience in their scientific aspect as may be expected of any educated person. The test will also include questions relating to India and its neighbouring countries especially pertaining to History, Culture, Geography, Economic Scene, General Polity and Scientific Research, etc.

(3) General Engineering : Mechanical Engineering : 

Theory of Machines and Machine Design, Engineering Mechanics and Strength of Materials, Properties of Pure Substances, 1st Law of Thermodynamics, 2nd Law of Thermodynamics, Air standard Cycles for IC Engines, IC Engine Performance, IC Engines Combustion, IC Engine Cooling & Lubrication, Rankine cycle of System, Boilers, Classification, Specification, Fitting & Accessories, Air Compressors & their cycles, Refrigeration cycles, Principle of Refrigeration Plant, Nozzles & Steam Turbines.

Properties & Classification of Fluids, Fluid Statics, Measurement of Fluid Pressure, Fluid kinematics, Dynamics of Ideal fluids, Measurement of Flow rate, basic principles, Hydraulic Turbines, Centrifugal Pumps, Classification of steel.
