# ME201 - Solid Mechanics

#### Instructor

Krishna Jonnalagada

#### Section

S2

#### Semester

Autumn ‘20

#### Course Difficulty

Difficulty can be broken down in 2 parts

- Content - Content is easy to follow in the first half but gets trickier in the latter half. For someone not concentrating in class, it is a good idea to pay attention in tutorials and stay in touch with the course flow
- Examination - Quizzes are easy, with class averages above 65% (purely an estimate) in most quizzes. Endsemester examinations are extremely challenging, with the maximum score in my year being 26/40

#### Time Commitment Required

On an average, other courses took less time compared to this. Mostly due to complicated concepts in the latter half

#### Grading Policy and Statistics

Grading policy: Based on the marks received by the topper. Here’s how it works

If the the topper scores X, then (your marks/X)*100 = Score

If score >= 90, you get AA

If 80<=score<90, you get AB

and so on.

There is also the rule that no student can fail if they score above 35% in a course so keep in mind that for FR, this rule may not apply exactly as is.

Example: Topper get 90, AA cutoff would be 81, AB cutoff would be 72 and so on

#### Attendance Policy

No attendance policy in normal lecture, tutorial have 10% weightage though

#### Pre-requisites

None

#### Evaluation Scheme

Best 5 out of 6 quizzes of 10% each,

Best n-1 out of n tutorials such that their total weightage is 10%

End Sems for 40 marks

#### Topics Covered in the Course

Fundamentals of mechanics of deformable solids. Concepts of stress and strain and their relationships. Fatigue and thermal stresses, creep. Equilibrium equations, strain displacement relation. Combined stresses, Mohr s circle diagram for stress and strain rosettes. Simple beams, bending moments, shear forces and stresses in beams. Torsion,

#### Teaching Style

Lectures and tutorial. I attended only 2 courses regularly in my third sem, this was one of them. Instructor is engaging

#### Tutorials/Assignments/Projects

Tutorials are easy to get full in, you can take help from TAs or friends

#### Feedback on Exams

Quizzes - Moderate to challenging

End semesters - Extremely Challenging, please study before this

#### Course Highlights

End semesters - maybe you have to be there to understand how difficult it is

#### Going Forward

List of courses that it can help in:

ME 202 Strength of Materials

ME 423 Machine Design

ME 601 Stress Analysis

ME 602: Fatigue, fracture and failure analysis

ME 616 Fracture Mechanics

ME 734: Vibro Acoustics
