Core Mechanical Engineering Subjects for Undergrad Students

Mechanical Engineering is one of the largest and oldest discipline of study. Generally Mechanical engineering deals with the energy and its transformation along with its utilization. It also emphasizes on designing and manufacturing different machines and machine parts. A perfect mechanical engineering undergraduate and post graduate program with the core mechanical engineering subjects can provide great technical background for a person. A mechanical engineer can work on fields like fluid mechanics, heat transfer , cooling, designing and other multidisciplinary professions. In essence , mechanical engineering is perfect for professions where a good understanding of technology is required. Mechanical engineering is interesting, challenging and provides a vast field of knowledge. So if you are preparing yourself for studying Mechanical engineering , it would be great if you look at the most basic mechanical engineering subjects. In this post I am going to discuss about them.

Core Mechanical Engineering Subjects for Undergrad level

Now lets discuss about the subjects for basic ME knowledge and contents they should cover.

  • Introduction to Mechanical Engineering or Basic Mechanical Engineering

Basic ME is mainly taught in the first semester of the 4 years course. This subject will cover the following topics.

Different types of energy sources (both conventional and non-conventional), boilers or steam generators and their integral parts ( mountings and accessories), Turbines (Impulse and reaction), IC engines, some basic automotive knowledge, a brief but important knowledge about pumps, compressors , fans and blowers, basic thermodynamics with refrigeration and air conditioning, simple laws of mechanics.

  • Mechanical drawing without CAD

Introduction to mandatory instruments required for the drawing, Different types of projections, Orthographic drawings, Isometric views, drawing of sections of different machine parts, auxiliary views etc.

  • Basic Thermodynamics 

Very important subject for mechanical engineers. Discusses the different aspects of thermal physics. Thermal engineering is another named used for Mecha. Engineers. Thermodynamics includes The three important laws of thermodynamics, basic concepts and properties of gases and vapors, systems, boundaries, thermodynamic cycles and processes, enthalpy, entropy and internal energy, refrigeration system, thermal comfort, psychrometry and combustion of engines.

  • Engineering Mechanics

It is divided into two main parts : statics and dynamics. Statics deals with forces in static and rigid bodies. It also discusses friction, moment of inertia ( both masses and areas), analysis of forces in truss and friction in stationary bodies.

Dynamics has the kinetics and kinematics. It mainly discusses the Newtonian physics. Friction in moving bodies, energy and forces in bodies having linear and rotational motion, impulse-momentum etc.

  • Mechanics of Solids or Solid Mechanics 

It deals with stress analysis of different load carrying members. Discusses Beams and Columns and equation of torsion.

  •  Numerical Analysis

Numerical Analysis Deals with the roots of the polynomials and transcendental equations. It also discusses linear and non linear algebraic equations. Different interpolation methods and first-order differential equation is also included in this course. One of the important feature of this course is the curve fitting.

  • Heat Transfer 

It discusses different theories of conduction, radiation and convection heat transfer.

  • Fluid Mechanics 

Basic hydrostatic equations, compressible and incompressible flows , Velocity , momentum, continuity equation. Flow metering, boundary conditions etc.

  • Machine Design 

Stress analysis in different pressure vessels , designing, bearing, gears, springs, breaks, clutches, ropes etc.

  • Mechanics of Machinery 

Mechanisms, Velocity , balancing of the rotating and reciprocating parts, vibration theories etc.

  • Instrumentation and Measurement 

Rudimentary principles of measurement. Discusses sensors, elements, response times and many more.

  • Internal Combustion Engines (IC engines)

Basic engines types, operations, cycles, SI and CI engines classifications. Performance measurements.

  • Power Plant Engineering 

Discusses about power plant loads, fuels, operations, maintenance, cycles, turbines. generation of power.

  • Refrigeration and building mechanical systems 

Basic refrigeration theorems, COP, different refrigeration systems, basic elements of refrigeration, cooling load calculation.

These are some of th core mechanical engineering subjects which are taught in engineering schools. So if you are interested in building your career as a mechanical engineer then you can follow these courses.
