ABOUT THE COURSE:This course is the second part of a three-part series which gives a brief introduction about basic mechanical engineering concepts. The course, due to the huge amount of content, is split into three: This course encompasses the concepts of fluid mechanics including the basic concepts of fluid mechanics, the basic and important theorems, laws, and equations governing fluid flow, types of flow, and advanced concepts like aerodynamics. The course also discusses thermal sciences concepts like properties, state, equilibrium, heat, energy, and work, processes, cycles, heat transfer methods, etc. Some optimization concepts like gradient descent and simplex methods are also covered in this course. The course will enable the student to have a firm grasp on these basic concepts and will serve as an introductory course which will discuss these topics and help students to develop interest and knowledge in basic and core concepts of mechanical engineering.INTENDED AUDIENCE: Students of all Engineering and Science disciplines.PREREQUISITES: The student should have completed two semesters of UG Engineering or Science program.INDUSTRY SUPPORT: HAL, NAL, SAIL, ISRO
