Course Description

The "Engineering Mechanics" course is specifically designed for Mechanical Engineering students who are eager to deepen their understanding of the fundamental principles of mechanics. This comprehensive professional course, spanning 40 hours and 32 minutes, is categorized under Engineering and Mechanics, and aims to equip learners with a robust foundation in engineering mechanics, which is essential for their academic and professional growth.

The course begins with an introduction to Engineering Mechanics, explaining key terminologies and setting the stage for more complex topics. Students will familiarize themselves with basic terms in a structured manner across several lectures, ensuring a solid grasp of the preliminary concepts before moving on.

Diving deeper, the curriculum covers critical aspects such as the system of forces, equilibrium conditions, and principles like the principle of transmissibility and the parallelogram law of forces. These foundational principles are essential for understanding the behavior of different forces acting on a body.

Students will also learn about the resolution and conditions of equilibrium of forces, enhanced by practical examples and numerical exercises. The concept of the free body diagram is thoroughly explained with multiple lectures dedicated to its applications, including Lami's theorem, which provides a powerful tool for solving force-related problems.

The course delves into the concepts of moments, including the moment of force and the calculation of resultant moments. Varignon's theorem and the principles governing couples are explored extensively, with relevant numerical exercises to solidify the understanding.

Structural analysis is another significant component of the course. Concepts of trusses and frames are discussed, along with their mathematical conditions and types of supports. Analytical methods for solving truss and frame problems are presented, accompanied by numerous practice questions to reinforce learning.

The topic of friction, including the concept of friction force and idealized graphs, is meticulously covered in a series of lectures. Students will gain insight into the location of centroid and center of gravity in various planes, complete with formulas and numerical examples.

The moment of inertia is addressed in detail, explaining its definition, calculation, and practical applications. The course covers both planar and mass moments of inertia, using the parallel and perpendicular axis theorems, radius of gyration, and more, with ample numerical practice to ensure competency.

Moving on to kinematics and kinetics of motion, the course tackles the equations of rectilinear and curvilinear motion, motion under gravity, and circular motion, providing a thorough understanding of these fundamental mechanics topics.

Lectures on impact mechanics differentiate between elastic and inelastic collisions and introduce the conservation of momentum and Newton's law of collision. Kinetics is further explored through D'Alembert's principle, along with a detailed discussion on work, power, and energy.

This meticulously structured course ensures that Mechanical Engineering students gain a profound knowledge of engineering mechanics, preparing them for further academic pursuits and professional excellence in their field.
