Mechanical roadmap

Mechanics, thermodynamics, design

Start with Engineering Mechanics, follow the steps in order, then build a project, prepare for interviews and earn your certificate.

Foundations

  1. Engineering Mechanics — Forces, moments and motion — the physics every machine obeys. The foundation of mechanical engineering: forces and their resultants, moments and couples, equilibrium and free-body diagrams, friction, centroids and moments of inertia, and the kinematics and dynamics of moving bodies.
  2. Strength of Materials — How parts stretch, bend, twist, buckle and eventually fail. Turn loads into stresses and deformations. Learn stress and strain, elastic behaviour, shear, bending, torsion, beam deflection, column buckling and fatigue — the tools used to size every shaft, beam, bolt and bracket safely.
  3. Thermodynamics — Energy, heat, work — and the rules that limit every engine. The science of energy conversion. Learn properties of substances, the laws of thermodynamics, entropy and enthalpy, heat engines, refrigerators and heat pumps, and the Otto, Diesel, Brayton and Rankine cycles behind cars, jets and power stations.

Core skills

  1. Fluid Mechanics — Pressure, flow and the machines that move fluids. How liquids and gases behave at rest and in motion. Learn fluid properties, hydrostatic pressure, continuity, Bernoulli's equation, momentum forces, laminar and turbulent flow, pipe losses, and the pumps, compressors and turbines that move fluids or extract energy from them.
  2. Heat Transfer — How heat moves — and how engineers speed it up or stop it. Thermodynamics says how much heat flows; heat transfer says how fast. Learn conduction, convection and radiation, thermal-resistance networks, and the design of heat exchangers — for engines, electronics cooling, buildings and process plants.
  3. Manufacturing — Turning designs into real parts — casting, forming, joining, cutting, printing. How parts are actually made. Learn casting, forging, welding, machining, CNC programming, grinding, industrial additive manufacturing and practical 3D printing — with the process physics, calculations and design-for-manufacture rules that decide cost and quality.

Advanced

  1. Machine Design — Sizing the elements every machine is built from. Apply mechanics and strength of materials to real machine elements. Learn to design shafts, gears, bearings, springs, couplings, brakes, clutches and fasteners — with the standard formulas, catalogue-selection methods, safety factors and failure modes engineers use every day.
  2. CAD/CAE — Design, document and simulate — the digital toolchain of modern engineering. The software engineers design and verify with. Learn 2D drafting in AutoCAD, parametric solid modelling in SolidWorks, Creo and NX, advanced surfacing in CATIA, and finite element simulation in ANSYS and Abaqus — with the underlying concepts, command syntax, scripting, and the checks that make results trustworthy.
  3. Robotics — Machines that sense, decide and move. The mechanical engineering of robots. Learn forward and inverse kinematics, robot dynamics and torque sizing, actuators and drives, sensors and feedback, trajectory planning and motion control, and how industrial robots are selected, programmed and deployed safely.
  4. Automotive — How vehicles go, stop, turn — and are going electric. Mechanical engineering on wheels. Learn IC engines, transmissions, braking, steering and suspension systems, electric and hybrid powertrains, and vehicle dynamics — with the calculations used to size, compare and tune real cars.
