JNTUK R23 B.Tech Mechanical II Year II Semester (2-2) Syllabus & Subject-wise Topics

Total: 15-1-10, 21 credits.

Also mandatory: a Community Service Project Internship of 8 weeks during the summer vacation — the source PDF lists this as a mandatory fieldwork requirement without any unit-wise syllabus, so there is nothing further to summarise here.

Industrial Management

introduces the management-science side of running a factory, from layout and productivity through to the financial and HR decisions a working engineer eventually has to weigh in on.

• Unit 1: Industrial engineering fundamentals, scientific management principles (Taylor, Fayol), plant layout types, and plant maintenance strategy
• Unit 2: Work study — method study, time study, work sampling, motion-time systems, and ergonomics principles
• Unit 3: Statistical quality control (control charts, sampling inspection) and total quality management, including Six Sigma basics
• Unit 4: Financial management — sources of finance, ratio analysis, working-capital management, and capital-budgeting techniques (NPV, IRR, payback period)
• Unit 5: Human resource management, job evaluation and wage incentives, and value engineering/supply-chain concepts

Complex Variables, Probability and Statistics

extends the maths sequence into complex analysis and statistical inference, both of which show up later in vibration analysis, signal processing, and quality-control coursework.

• Unit 1: Analytic functions, Cauchy-Riemann equations, and complex integration via Cauchy’s integral theorems
• Unit 2: Taylor/Laurent series expansions, types of singularities, and the residue theorem for evaluating real integrals
• Unit 3: Probability review, random variables, and standard distributions (Binomial, Poisson, Uniform, Normal)
• Unit 4: Sampling theory, the central limit theorem, and t/chi-square/F-distributions for point and interval estimation
• Unit 5: Hypothesis testing — null/alternative hypotheses, Type I/II errors, and one- and two-sample tests

Manufacturing Processes

surveys the major ways raw material becomes a finished mechanical part, giving students a working vocabulary across casting, joining, forming, and additive routes before they specialise later.

• Unit 1: Metal casting — pattern making, moulding, gating/risers, furnace types, solidification defects, and special processes like die and investment casting
• Unit 2: Welding processes (gas, arc, resistance, friction, laser, electron-beam) and their defects, plus soldering and brazing
• Unit 3: Bulk deformation processing — hot/cold working, forging, rolling, and extrusion/wire-drawing
• Unit 4: Sheet-metal forming (blanking, deep drawing, bending) and high-energy-rate forming methods
• Unit 5: Additive manufacturing — process classification, materials, and post-processing of AM parts

Fluid Mechanics & Hydraulic Machines

covers how fluids behave at rest and in motion and how that behaviour is harnessed in pumps and turbines, a prerequisite for thermal and hydraulic system design later on.

• Unit 1: Fluid statics — pressure measurement, manometry, and buoyancy/stability of floating bodies
• Unit 2: Fluid kinematics and dynamics — continuity, Euler’s and Bernoulli’s equations, and pipe-flow losses
• Unit 3: Boundary layer theory and dimensional analysis via the Buckingham Pi theorem
• Unit 4: Turbomachinery basics — force of jets on vanes, and impulse/reaction turbines (Pelton, Francis, Kaplan)
• Unit 5: Turbine and pump performance — unit/specific quantities, cavitation, and centrifugal/reciprocating pump characteristics

Theory of Machines

the kinematics and dynamics course behind every mechanism, gear train, and rotating assembly a mechanical engineer will later design or troubleshoot.

• Unit 1: Mechanism classification, degrees of freedom, Grashof’s law, and common mechanisms like quick-return and straight-line linkages
• Unit 2: Displacement, velocity, and acceleration analysis of mechanisms, including instantaneous centres and Coriolis acceleration
• Unit 3: Gyroscopic effects in vehicles and aircraft, plus gear profile theory (involute/cycloidal) and gear trains
• Unit 4: Balancing of rotating masses and cam/follower design (displacement diagrams, pressure angle, undercutting)
• Unit 5: Free and forced vibration of single-degree-of-freedom systems, plus turning-moment diagrams and flywheel design

Fluid Mechanics & Hydraulic Machines Lab

puts the turbomachinery and flow-measurement theory from the lecture course into practice on real pumps, turbines, and metering devices.

• Turbine and pump performance testing: Pelton wheel, Francis turbine, Kaplan turbine, single- and multi-stage centrifugal pumps, and reciprocating pumps
• Flow-measurement calibration: venturimeter, orifice meter, and pipe friction-factor determination
• Additional exercises: impact-of-jet-on-vanes testing and turbine flow-meter measurement

Manufacturing Processes Lab

hands-on casting, welding, and forming practice that mirrors the process theory covered in the lecture course.

• Pattern-making and sand-testing exercises: single-piece and split patterns, sieve/clay/moisture/strength/permeability tests, and mould preparation
• Joining exercises: gas cutting, manual metal arc welding, TIG/MIG welding, spot welding, brazing, and soldering
• Forming and additive exercises: injection and blow moulding, sheet-metal operations, deep drawing/extrusion, and 3D-printed parts

Soft Skills

a communication and employability-focused course meant to prepare students for interviews, teamwork, and workplace interpersonal dynamics alongside their technical training.

• Intra-personal and inter-personal skills: SWOT analysis, emotional intelligence, time/stress management, teamwork, negotiation, and leadership
• Verbal skills: listening, speaking, reading, and writing (including resumes and statements of purpose)
• Non-verbal and interview skills: body language, dress code, and structured interview technique

Design Thinking & Innovation

introduces a human-centred design process so students learn to frame problems and prototype solutions, not just apply existing formulas.

• Unit 1: Design fundamentals and the history of design thinking as a discipline
• Unit 2: The design thinking process — empathise, analyse, ideate, prototype — applied to social innovation
• Unit 3: Innovation versus creativity, and building teams that sustain innovation
• Unit 4: Product design — problem framing, product strategy, and specification-writing
• Unit 5: Applying design thinking to business strategy, startups, and business-model testing
