Hey dear students I am again updating the course with addition of recent Question paper of Pune University held on Jan-2024 with complete solution in two video lectures and one resource file along with question paper in 2 image pages. I was guest faculty at one of the reputed Engineering colleges of Pune and taught this complete subject and most of the topics are reflected in question paper. So my intension to give you the best as possible and to gain more confident and knowledge in the said subject. I will also update all the units ( I to VI) step by step so as to get more simplified version of the subject. Till then have a nice day and best of luck. Also don't forget to provide your valuable feedback after completion of the course. Thanks.This is fourth and final update uploaded in the course on 15.06.2023. Answer sheet no. 4 (Question number 7 and 8 with answers) of Question Paper of April-2022 of SPPU university, Pune added. ( Video Lecture + Resource File). So its beneficial for you all how to write answers in final exam..Third update uploaded in the course on 01.06.2023. Answer sheet no. 3 (Question number 5 and 6 with answers) of Question Paper of April-2022 of SPPU university, Pune added. ( Video Lecture + Resource File). Second update uploaded in the course on 20.05.2023. Answer sheet no. 2 (Question number 3 and 4 with answers) of Question Paper of April-2022 of SPPU university, Pune added. ( Video Lecture + Resource File). First Update uploaded in the course on 02-05-2023 Answer sheet no. 1 (First 2 questions and answers) of Question Paper of April-2022 of SPPU university, Pune added. ( Video Lecture + Resource File). Third update will be soon uploaded after response to above. Mechanical Systems of Engineering / Systems in Mechanical Engineering / Elements of Mechanical Engineering is the subject designed for First year year Engineering students. This is to enable all engineering students to get acquainted with the subject and also to get clear ideas of the mechanical devices / appliances which come across in real life. The course consists of Theoretical as well as numerical part. Numericals are incorporated as per syllabus structure so it is very beneficial for beginners to get an idea about method / approach to solve the same. The data required for preparation of the subject takes more time as to search through various books and web sites. The course hence designed with the requirement of the students so that they can save lot of time and also gain confidence to get through the subject with good score.The course is divided into six units as below:Unit-I: Introduction to Energy sources and its Energy ConversionsUnit-II: Introduction to Thermal EngineeringUnit-III: Introduction to Vehicles / Automobile Engineering and their SpecificationsUnit-IV: Various Systems of Vehicle / AutomobileUnit-V: Introduction to Manufacturing ProcessesUnit-VI: Engineering Mechanisms and their application in Domestic appliancesUnit I Introduction of energy sources & its conversion Energy sources: Thermal energy, Hydropower energy, Nuclear energy, Solar energy, Geothermal energy, Wind energy, Hydrogen energy, Biomass energy and Tidal energy.
