Mechanical Engineering 3rd Semester K scheme Syllabus

Hello everyone Tejas from this side. In this post we are going to see Mechanical Engineering 3rd semester Case Scheme Syllabus.

Show guys in previous post we have done our Civil engineering Syllabus of MSBTE and we are moving forward for the mechanical engineering.

Also a few days ago we have completed computer engineering syllabus also.

Now today in this post we are going to share with you mechanical engineering syllabus along with subtopics and unit of each subject.

Yes friends this semi stars content approximately eight subjects.

The subject Cont strength of material fluid mechanics and machineries thermal engineering production engineering basic electrical and electronic essence of Indian Constitution Computer Aided Crafting and fundamental of Python programming.

So in this semester MSBT has covered cover subject along with the programming and software based subject for increasing the critical thinking of the students.

Strength of material fluid mechanics and machineries thermal engineering production drawing computer editor drafting these are the subjects related to core mechanical engineering.

And the subject basic electrical and electronics is going to the electrical and electronics engineering and the subject fundamental of Python programming is goes to the computer engineering that means you are able to understand the Python programming along with the basic electricals and electronics components in this semester.

So friends This semester is of 900 marks and most of the marks are in your head because some practical subjects are involved in this semester.

I know there is maybe the list of subject is huge that means covering the 8 subject in one semester within the 6 month is eventually not possible but friends focus on the studies if you are doing great then it will benefit to gain the knowledge of computer electrical electronics and also you become and pure mechanical engineering Along with the knowledge of all branches.
