Basque PAU Technology & Eng II study guide
Basque PAU Technology & Eng II · Work through your exam, one topic at a time.
Tecnología e Ingeniería II is the second-year Bachillerato subject examined in the Euskadiko Unibertsitatera Sartzeko Ebaluazioa (EvAU/PAU) for students heading into engineering, architecture and technical degrees at Basque universities. It is a subject-specific exam within the admission phase, so it usually matters for weighting the admission score in engineering-related degrees rather than for simply qualifying. The Basque PAU Technology & Eng II study guide has 9 sections and about 3,588 words.
01Materials: properties, structure, testing and selection
Materials questions in the Basque PAU Technology & Engineering II paper typically ask you to link structure to properties, select a material for a stated service condition, and interpret a mechanical test. You need numbers as well as names: density, Young's modulus, yield strength, toughness and cost.
434 words, about 2 min02Mechanical systems and mechanisms: kinematics, dynamics, transmission and transformation
Kinematics (motion without forces), dynamics (forces, torque, energy), and transmissions that change speed, torque or direction. Expect mobility calculations, velocity ratios, gear trains, belt/chain drives, cams and power screws.
409 words, about 2 min03Electrical and electronic circuits: DC/AC analysis, components and basic electronics
DC circuit analysis (Ohm, Kirchhoff, series/parallel, Thévenin), AC steady state (RMS, phasors, impedance, resonance, power factor), and basic electronics (diodes, BJT switching, op-amps, logic interface). KCL: sum of currents at a node = 0; KVL: sum of voltages around a loop = 0.
409 words, about 2 min04Control and automatic systems: open/closed loop, sensors, actuators and logic control
Block diagrams, feedback, steady-state error, stability, sensor/actuator selection, and combinational logic for automated systems. Open loop: the controller acts without measuring the output; cheap but sensitive to disturbance.
394 words, about 2 min05Pneumatic and hydraulic systems: components, schematics and circuit design
Symbol recognition (ISO 1219), circuit design for cylinders and motors, pressure/flow control, force and speed calculations, and safety. Pascal's principle: pressure is transmitted equally, p = F/A.
409 words, about 2 min06Manufacturing and production systems: machining, forming, joining and metrology
Process selection for a shape/material/volume, machining parameters, forming and joining, and metrology with tolerances. Turning: the workpiece rotates and a single-point tool feeds; cutting speed v = πDN/1000 (m/min), feed f (mm/rev), depth of cut.
380 words, about 2 min07Energy and power: energy sources, generation, conversion and environmental impact
Energy sources and conversion chains, efficiency, power calculations, capacity factor, and environmental impact. Fossil: chemical → thermal → mechanical → electrical; emissions include CO2, SO2 and NOx.
367 words, about 2 min08Engineering project and technical drawing: representation, dimensioning and design process
Orthographic projection, dimensioning to ISO, sections, tolerances, scales, and the design process from brief to solution. First-angle projection (ISO, Europe): the object is between observer and plane; the front view is placed above the top view, and the left view is placed on the right.
410 words, about 2 min09Technological innovation and digital tools: CAD/CAM, ICT and product development
The product development cycle, CAD/CAM/CIM, simulation, ICT, and how innovation is protected and managed. CAD: 2D drafting and 3D parametric modelling (sketch → constraints → features → assembly → drawing).
