Syllabus of the RRB JE mechanical exam:
The RRB JE ME syllabus is given below.
- Mathematics- Under this you must prepare in detail algebra, number system, profit, loss, time, distance, work, etc and every concept of mathematics.
- General science- Under this major subject like physics, chemistry, and life sciences should be covered.
- General awareness- Try to cover every information relating to polity, environment, scientific field, sports, geography, history, etc.
- Basics of computer- Under this the candidate must be good enough in understanding the basic concepts of computer applications.
- Engineering mechanics- This solution is devoted to the solution of mechanics problems through the integrated application of mathematics and engineering principles. The main emphasis is laid on the physical principles of modern engineering design.
- Material science- This study is all about the properties of solid materials and also how to determine them with the help of material composition and structure. The material science study is followed by four categories including metals, polymers, semiconductors and ceramics. This will also cover mechanical properties of the material- tensile strength, ductility, hardness, toughness, brittleness etc.
- Strength of material- Also, known as mechanics of material, this will tell you the ability to withstand an applied load failure or any plastic deformation. This study will calculate the stresses and strains on the materials.
- Machining- This study includes the working principle of lathe, general and special operations, cutting fluids, coolants and lubricants, introduction to shaper, slotter, plainer, heat treatment process applied to gears.
- Welding- This set includes introduction and classification of welding processes, pros and cons of welding, arc welding, choice of electrodes, gas welding, applications of solders and fluxes, flame-cutting processes etc.
Other subjects like grinding and finishing process, metrology, fluid mechanics and hydraulic machinery, industrial management and thermal engineering. It is important to prepare well for these subjects to ace the exam.
