ESE ME Prelims study guide
ESE ME Prelims · Work through your exam, one topic at a time.
The Engineering Services Examination (Preliminary) in Mechanical Engineering is a UPSC-conducted screening stage for engineering graduates aiming at Group A and Group B technical posts in the central government. The Commission lists it among its active examinations on upsc.gov.in, but the official pages give no current figures for paper structure, marks, duration, cut-offs or fees, so candidates must read the annually issued examination notice before planning. The ESE ME Prelims study guide has 9 sections and about 2,641 words.
01Engineering Aptitude and General Principles
This domain tests the quantitative and professional-judgment layer of ESE Prelims Paper I: unit and dimension discipline, error handling, engineering drawing conventions, safety principles, standards, and professional ethics. Questions are usually short but punish loose notation.
304 words, about 2 min02Fluid Mechanics
ESE Prelims Paper II tests property definitions, hydrostatics, control-volume analysis, pipe losses, dimensional analysis, and turbomachinery selection. Most numerical items reduce to one conservation equation plus a loss model.
303 words, about 2 min03Thermodynamics
The exam tests property relations, the first and second laws, gas cycles, steam cycles, and combustion basics. Sign conventions and absolute temperatures are common mark-losers.
311 words, about 2 min04Heat Transfer
Questions cover conduction resistance networks, convection correlations, radiation exchange, and heat-exchanger sizing. The exam favors combined-mode and LMTD problems.
278 words, about 1 min05Theory of Machines
This domain tests mobility, velocity and acceleration analysis, cams, gears, governors, flywheels, balancing, and vibration. Mechanism counting and gear ratios are high-yield.
304 words, about 2 min06Machine Design
The paper tests static failure theories, fatigue design, shaft–key–bolt joints, bearings, springs, and design for manufacture. Candidates lose marks by choosing the wrong failure criterion.
306 words, about 2 min07Strength of Materials
This domain covers stress–strain, beams, torsion, columns, and combined loading. Free-body diagrams and boundary conditions decide most answers.
264 words, about 1 min08Manufacturing and Production Engineering
The exam tests casting, forming, welding, machining, metrology, and tolerances. Numerical items often use Taylor's tool life, allowance, or gauge design.
273 words, about 1 min09Industrial Engineering
This domain tests work study, inventory control, project management, quality control, and plant layout. The exam expects formula recognition and correct units.
