MPPSC SES Mechanical study guide
MPPSC SES Mechanical · Work through your exam, one topic at a time.
The MPPSC State Engineering Service Examination (Mechanical Engineering) is a Madhya Pradesh Public Service Commission recruitment test used to shortlist candidates for state government engineering posts, typically Assistant Engineer and equivalent technical roles in departments such as PWD, Water Resources, and energy utilities. It is intended for mechanical engineering graduates who want a stable public-sector technical career in Madhya Pradesh rather than private industry or central services. The MPPSC SES Mechanical study guide has 11 sections and about 3,293 words.
01Engineering Mathematics and Basic Engineering Sciences: Formula-Driven Accuracy
Engineering Mathematics and Basic Engineering Sciences covers linear algebra, calculus, differential equations, numerical methods, and the foundation physics and electrical concepts that later mechanical subjects assume. MPPSC SES papers favour short computational items over long proofs, so formula recall and numerical accuracy matter more than derivation length.
337 words, about 2 min02Engineering Mechanics and Strength of Materials: Equilibrium to Buckling
A body in equilibrium satisfies ΣF = 0 and ΣM = 0. Draw the free-body diagram first, replace supports by reactions (roller: one normal; pin: two components; fixed: two forces plus a moment), and treat a two-force member as carrying force along its axis.
324 words, about 2 min03Theory of Machines and Mechanical Vibrations: Mechanisms, Gears and Resonance
Degrees of freedom by Grübler's criterion: F = 3(n − 1) − 2j − h, where n includes the frame, j is the number of lower pairs and h the number of higher pairs. A four-bar linkage has one DOF; a slider-crank also has one.
340 words, about 2 min04Design of Machine Elements: Failure Theories, Fatigue and Shaft Sizing
Design applies a factor of safety to a chosen strength: n = S/σ. For ductile materials use maximum shear stress (Tresca) or von Mises; for brittle materials use maximum principal stress (Rankine).
296 words, about 1 min05Fluid Mechanics and Fluid Machinery: Bernoulli, Losses and Turbomachines
Pressure at depth p = ρgh; absolute pressure = gauge + atmospheric. Continuity gives A₁V₁ = A₂V₂, and Bernoulli along a streamline gives p/ρg + V²/2g + z = constant.
271 words, about 1 min06Thermodynamics, Heat Transfer and Energy Systems: Cycles and Thermal Resistance
First law for a closed system: Q − W = ΔU; for steady flow: q − w = Δh + ΔKE + ΔPE. The second law limits performance: no engine exceeds Carnot efficiency 1 − T L/T H, with temperatures in kelvin.
280 words, about 1 min07Manufacturing Processes and Production Engineering: Casting, Welding and Machining
Casting: pattern allowances for shrinkage, draft and machining; riser sized by Chvorinov's rule t = B(V/A)² and placed at the hottest section; gating ratio controls turbulence. Welding: arc welding uses a consumable or tungsten electrode; TIG suits thin, clean sections, MIG is faster on thicker plate; resistance welding relies on I²Rt at the interface.
299 words, about 1 min08Industrial Engineering and Production Management: Work Study to Quality Control
Method study follows select–record–examine–develop–install–maintain. Time study sets standard time = observed time × rating factor + allowances.
280 words, about 1 min09Materials Science and Metallurgy: Crystal Structure, Phase Diagrams and Heat Treatment
Metals crystallise as BCC, FCC or HCP. FCC (Cu, Al, γ-iron) has 4 atoms per unit cell and APF 0.74; BCC (α-iron, W) has 2 and 0.68; HCP has 6 and 0.74.
273 words, about 1 min10General Studies: Madhya Pradesh Focus with Polity and Environment
General Studies in MPPSC SES tests Madhya Pradesh history, geography, polity, economy, schemes, current affairs, and general science and environment. Questions are factual and often state-linked, so district-level and scheme-level detail matters.
287 words, about 1 min11Aptitude and Engineering Ethics: Shortcuts and Professional Obligations
Successive percentage changes a% and b% give a + b + ab/100. Convert km/h to m/s by multiplying by 5/18; for a train crossing a platform, add train length to platform length.
