GATE Wallah (English)・29 minutes read
The text introduces Engineering Mechanics as a crucial subject for various exams, detailing the instructor's background, course content, recommended books, and the importance of understanding mechanics principles. It emphasizes the division of mechanics into Statics, Dynamics, Kinematics, and Kinetics, highlighting key topics like forces, moments, equilibrium, and motion analysis for comprehensive preparation.
Insights
- Mechanics in engineering is the study of forces on bodies at rest or in motion, applied to mechanical design, divided into mechanics of solids and fluids, with further subdivisions like mechanics of rigid and deformable bodies, highlighting the importance of simplifying calculations by assuming rigidity and delving into statics and dynamics, including kinematics and kinetics.
- Engineering mechanics is a foundational subject crucial for various exams like GATE ME, GATE XC, Engineering Services, SSC, and semester exams, carrying significant weightage in GATE exams, with recommended books and detailed syllabus covering topics from basic concepts to Lagrange's equation of motion, emphasizing the need for understanding this subject for related topics like strength of materials, theory of machines, and vibrations, with the course structure including approximately 30-35 lectures over 6-8 weeks, providing comprehensive preparation through theory, numericals, and practice questions available on the PW app.

Engineering Mechanics Course for GATE Preparation
- The problem discussed involves kicking a football at a 30-degree angle, focusing on determining the maximum height and range without considering the applied force.
- Kinematics is highlighted as the study of motion without considering forces, while kinetics involves studying both forces and motion, combining statics and kinematics.
- The syllabus for the engineering mechanics course includes 11 chapters, starting with basic concepts covering forces, moments, and vector addition, progressing to equilibrium, friction, truss, frames, centroid, moment of inertia, kinematics, and rigid bodies, culminating in Lagrange's equation of motion.
- The course is recommended for GATE ME, GATE XC, Engineering Services, SSC, and semester exams where engineering mechanics is a subject.
- Recommended books for further study include RC Hibbeler for Statics and Dynamics, BRN Johnston, and AK Tayal for concise and relevant questions for GATE preparation.
- In GATE ME, engineering mechanics carries a weightage of 6-8 marks on average, with 9 marks in some sets, while in GATE XC, it constitutes at least 15 marks out of the 35 marks allocated to solid mechanics.
- Understanding engineering mechanics is crucial not only for GATE but also for related subjects like strength of materials, theory of machines, and vibrations, as it lays the foundation for these topics.
- The course will span approximately 30-35 lectures over 6-8 weeks, with classes scheduled from Monday to Friday, 7 pm to 8:30 pm, covering theory, numericals, and homework questions.
- Lecture notes and practice questions will be available on the PW app under the free batch for GATE 2024, ensuring comprehensive preparation for the subject.
- Students are encouraged to attend the live classes punctually at 7 pm to engage in discussions, ask questions, and benefit from the course effectively.
