Engineering

In engineering you remember system vocabulary, quantities, units and modelling methods. Lumi has you recall them so you can read a diagram or a specification without getting lost.

How to turn this subject into cards

In this subject, separate system vocabulary (information chain, energy chain, sensor, actuator), quantities and their units, methods (diagrams, balances, models) and orders of magnitude. Make one card per diagram, with what each block stands for. The common trap is recognising a diagram without being able to explain what it models, or mixing up power and energy. Lumi quizzes you on definitions and on reading the blocks. A large review of the research rated practice testing as high utility (Dunlosky et al., 2013). It helps you remember vocabulary, formulas, units and method steps.

Engineering · teach this card to Lumi

Efficiency is useful energy output divided by total energy input. Stress is force divided by area and is measured in pascals. A sensor converts a physical quantity into an electrical signal. An actuator converts energy into movement. The factor of safety is the ratio of failure load to working load.
