Catalonia PAU Technology and Engineering II study plan

Catalonia PAU Technology and Engineering II · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Mechanical systems and machine elements: transmission, support, union and motion conversion & Materials: properties, structure, selection and environmental criteria

  • Classify the six classical machine elements (axles/shafts, bearings, gears, belts, clutches/brakes, fasteners) and state the load each transmits or supports

  • Compute velocity ratio, torque and output speed for a two-stage gear train and a belt-and-pulley pair, showing units at each step

  • Relate the four material families (metals, ceramics, polymers, composites) to stiffness, toughness and density using a qualitative Ashby-style comparison

  • Match a stated service requirement (wear resistance, low mass, electrical insulation, corrosion) to a material family and justify the choice in two sentences

Your checkpoint

A one-page formula sheet for transmission ratios, efficiency chains and mechanical stress, plus five solved gear/belt problems with checked units

Week 2

Mechanical systems and machine elements: transmission, support, union and motion conversion & Materials: properties, structure, selection and environmental criteria

  • Solve screw, rack-and-pinion and cam-follower motion-conversion problems, converting rotary input to linear output

  • Select a rolling bearing type from radial/axial load and speed conditions and justify the choice

  • Distinguish reversible from non-reversible joints (welded, riveted, bolted, adhesive) and pick one for a given disassembly requirement

  • Describe how crystal structure and defects (grains, dislocations, alloying) explain ductility and hardness in metals

  • Apply an environmental selection criterion (recyclability, embodied energy, toxicity) to reject a technically valid material option

Your checkpoint

A comparative table of three candidate materials for one component, with mechanical and environmental criteria scored and a defended final pick

Week 3

Electrical and electronic circuits: direct and alternating current, components, analysis and measurement & Control systems and automation: open/closed loop, sensors, actuators, logic and block diagrams

  • Apply Ohm's law, Kirchhoff's laws and series/parallel reduction to solve mixed DC resistor networks

  • Compute power dissipation and select a resistor rating with a safety margin

  • Analyse series RLC AC circuits: calculate impedance, phase angle and resonant frequency

  • Distinguish open-loop from closed-loop control and identify the sensor, controller and actuator in a described system

  • Interpret a simple block diagram and derive the overall transfer relationship of series and feedback blocks

Your checkpoint

A worked problem set of two DC networks and one AC RLC circuit, each with a labelled schematic, full calculation and a stated result with correct units

Week 4

Electrical and electronic circuits: direct and alternating current, components, analysis and measurement & Control systems and automation: open/closed loop, sensors, actuators, logic and block diagrams

  • Read and draw pneumatic/hydraulic schematics using ISO 1219 symbols for valves, cylinders and actuators

  • Design a circuit for a double-acting cylinder with 5/2 valve and speed control, and explain the function of each element

  • Convert between truth tables, Boolean expressions and logic gate diagrams for two- and three-input functions

  • Simplify a Boolean expression algebraically or with Karnaugh maps and implement it with NAND gates

  • Size a cylinder force and flow requirement from pressure and bore, checking units

Your checkpoint

One complete fluid-power circuit schematic with symbol legend and a truth-table-to-NAND implementation for a three-input safety interlock

Week 5

Manufacturing and production: processes, machining, forming, joining and quality & Technical drawing and graphical expression: views, dimensioning, sections and CAD conventions

  • Compare casting, forging, rolling, extrusion and machining by achievable tolerance, cost and suitable batch size

  • Choose a joining process (arc welding, MIG, riveting, adhesive, threaded fastener) for a stated material and load case and justify it

  • Produce three-view orthographic drawings (front, plan, side) of a simple part applying first-angle projection correctly

  • Add dimensions, tolerances and a section view to a drawing following standard conventions

  • Identify the quality-control stage (incoming, in-process, final) appropriate to a described defect risk

Your checkpoint

A fully dimensioned first-angle three-view drawing of one part, including one section view and a tolerance note, plus a short process-selection justification

Week 6

Energy, resources and sustainability: sources, conversion, efficiency and environmental impact & Product design, projects and technological innovation: methods, documentation and evaluation

  • Compute energy efficiency and primary-energy demand for a conversion chain (e.g. fuel to electricity to motor output)

  • Compare renewable and conventional sources on capacity factor, dispatchability and land or resource use

  • Quantify the environmental impact of a design choice using embodied energy or CO2 payback reasoning

  • Apply a structured design method (requirements, constraints, concept generation, criteria matrix) to select among three concepts

  • Draft a project document containing objective, specifications, budget outline and evaluation criteria

Your checkpoint
