a hands-on introduction to Python meant to give mechanical students a general-purpose scripting and data-handling skill they can apply to engineering computation, not just software electives.

• Core language exercises: syntax, control structures, functions/modules, lists/tuples, dictionaries/sets, string handling, and file I/O
• Applied exercises: exception handling, object-oriented programming, and using third-party libraries and packages
• Data-focused exercises: data manipulation and visualization with Pandas/Matplotlib, plus basic web-scraping, API, and database (SQLite) interaction

Embedded Systems and IoT

introduces microcontroller interfacing and internet-connected sensing, the building blocks behind smart manufacturing and mechatronic systems covered later in the programme.

• Embedded systems experiments: sensor signal acquisition, PWM generation, serial/SPI communication, and stepper-motor and accelerometer interfacing using Arduino
• IoT experiments: Raspberry Pi setup and Python-based development, distance/LED interfacing, public API/SDK interaction, and Zigbee protocol basics

Environmental Science

a mandatory audit course covering ecological literacy and environmental law, meant to instil awareness of the sustainability trade-offs engineers create.

• Unit 1: Multidisciplinary nature of environmental studies and the use/over-exploitation of forest, water, mineral, and food resources
• Unit 2: Ecosystem structure and function, food chains/webs, and biodiversity conservation
• Unit 3: Causes and control of air, water, soil, marine, noise, and thermal pollution, plus solid-waste and disaster management
• Unit 4: Sustainable development, water conservation, environmental legislation (Environment Protection Act, Water Act, Air Act, Wildlife Protection Act, Forest Conservation Act)
• Unit 5: Population growth, human health, and the role of information technology and value education in environmental welfare

JNTUK R23 B.Tech Mechanical IV Year II Semester (4-2) Syllabus & Subject-wise Topics

by Rishi | Jul 10, 2026 | JNTUK R23 Syllabus

Total: 12 credits.

IV Year II Semester in the R23 Mechanical Engineering structure consists entirely of a full-semester internship and project work — there are no theory subjects, electives, or a unit-wise syllabus for this semester in the source PDF; the credit is earned through the internship/project placement itself.
