The North Rhine-Westphalia Abitur Technology - independent engineering foundations study guide has 7 sections and about 3,347 words.
01Materials, testing and selection
This independent materials study 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.
489 words, about 2 min02Statics, strength and mechanical transmission
This foundations field 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.
555 words, about 3 min03Manufacturing, machining models and metrology
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.
490 words, about 2 min04Measurement, feedback, PLC and automation
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.
489 words, about 2 min05Pneumatic and hydraulic model reasoning
This foundations field 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. Ideal force relations can be shared, but compressibility, leakage, friction and flow-reference conditions matter; not every liquid-flow simplification transfers unchanged to compressed air.
440 words, about 2 min06Energy, thermal machines and environmental assessment
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.
429 words, about 2 min07Engineering models, drawings, evidence and project decisions
Engineering reasoning starts with a purpose, a system boundary and the assumptions that permit a calculation. A free-body diagram, circuit diagram, energy-flow model and process chart represent different relationships.
