Galicia PAU Technology and Engineering II study guide
Galicia PAU Technology and Engineering II · Work through your exam, one topic at a time.
Tecnoloxía e Enxeñaría II is the second-year subject of the Galician bacharelato science-and-technology track, and its PAU exam is the optional paper taken by students who want the subject to count toward their university admission score. It is aimed at candidates heading for engineering degrees, architecture, industrial design or technical vocational pathways, and it rewards the ability to solve quantitative problems rather than to recite definitions. The Galicia PAU Technology and Engineering II study guide has 7 sections and about 2,737 words.
01Materials: properties, structure, testing and selection
This block of the PAU Tecnología e Ingeniería II checks whether you can go from a material's internal structure to a measurable property and from there to a choice justified with numbers. The usual content is metals, polymers, ceramics and composites, the tensile test with its stress–strain curve, hardness and impact tests, and selection using specific indices.
409 words, about 2 min02Mechanical systems: statics, strength of materials and mechanisms
Here the exam asks for free-body diagrams, support reactions, stress calculations in bars and beams, and the kinematics of mechanisms. It is the block where a sign error or a missing reaction costs the most marks, because the whole exercise follows from it.
441 words, about 2 min03Electrical and electronic systems: circuits, machines, power electronics and digital electronics
This domain covers DC and AC circuit analysis, transformers and rotating machines, power converters and Boolean logic. The exam usually mixes a quantitative circuit problem with a simplification of a logic function.
368 words, about 2 min04Control systems and automation: sensors, actuators, open/closed loop, PLCs and robotics
This domain tests whether you can describe a control loop, choose a sensor from its specifications, explain what a PLC does in each scan and justify a robot morphology. Expect questions on sensor characteristics, PID behaviour, PLC I/O and degrees of freedom.
387 words, about 2 min05Pneumatics and hydraulics: components, circuit design and simulation
The exam asks for cylinder forces and speeds, correct interpretation of ISO 1219 symbols and the design or reading of a circuit with directional, flow and pressure valves. Hydraulics and pneumatics share the same formulas but differ in pressure level, compressibility and achievable force.
367 words, about 2 min06Manufacturing and production systems: machining, forming, joining, metrology and quality
This section tests process calculations in machining, the logic of forming and joining processes, correct use of measuring instruments and statistical quality control. The numeric part is usually cutting speed, machining time or a capability index.
390 words, about 2 min07Energy and environmental technology: sources, conversion, efficiency and sustainability
This domain asks you to compare energy sources, apply conversion efficiencies with correct units and assess sustainability. Typical items are a hydraulic or wind power calculation, a thermal efficiency question and a comment on the environmental impact of the energy mix.
