Pre Requisites: Strength of Materials - I

Course Objectives:

Study of the subject provides the understanding of principal stress, strains, springs, columns, and structures.

Course Outcomes:

At the end of the course, the student will be able to 

-Determine stresses in the member subjected to Torsion 

-Analyze columns and struts

-Understand the concept of direct and bending stresses 

-Analyze and design springs, thin and thick cylinders 

-Understand the concept of unsymmetrical bending.

10 Years of Experience

Engineering Mathematics(M2) is one of the most critical subjects for B-tech students (common to all branches of engineering). A clear understanding obviously helps in dealing core subjects in a better way. Here in this course we start with the basics of the subject and cover the complete syllabus. I have been taking this course since last 6 years with at least 4 batches each year. And It has helped the students a lot.

"The experience was beyond expectation, Sir has in depth and immense knowledge about the subject and can easily explain problems while explaining thoroughly the procedure and the concept of that problem, He is the best there is. I did not like Maths that much but learning it from him made maths challenging and fun again. Most teachers would not care about the student and just rush with the explanation to cover the subject, However he will make sure you understand the problem and the fundamentals of it in a polite manner. 10/10 would recommend to anyone seeking to improve their skill in mathematics and pass your exams or just basically get better at it.

"First of all ,thanks to urbanpro for getting me in contact with Abdul sir ! For the first time I started feeling comfortable with mathematics and I can say that is solely because of the teaching of this sir , he exactly knows how to make a student understand a method in the easiest possible way and sir is not very strict as well so that we don't shy away from asking him doubts.
