Engineering ScienceQ&A by dot point
A short Q&A bank for every Scotland Engineering Science syllabus dot point. Each question and answer is drawn directly from our worked dot-point page, so you can scan key concepts before opening the long-form answer.
Area: Electronics and control
- The capacitor charge and discharge through a resistor, the time constant, and passive RC filters selecting signals by frequency.3Q&A pairs
- Combinational logic built from logic gates, described by truth tables and Boolean expressions, simplified using Boolean algebra and Karnaugh maps.3Q&A pairs
- Control systems described by the system model, the difference between open-loop and closed-loop control, and the role of feedback, the error signal and the components of a closed-loop system.3Q&A pairs
- Programmable control with a microcontroller: inputs and outputs, programs described by flowcharts and pseudocode, and the use of loops, decisions and sub-routines.3Q&A pairs
- The operational amplifier as a high-gain difference amplifier, and the inverting, non-inverting, summing and difference configurations with their closed-loop gain relationships and saturation.3Q&A pairs
- Sequential logic with memory: flip-flops storing a bit, counters dividing and counting pulses, and astable and monostable timing circuits.3Q&A pairs
Area: Engineering project and analysis
- Engineering analysis and modelling: mathematical modelling and simulation, data handling with graphs and uncertainty, and the correct use of quantities, SI units and prefixes.3Q&A pairs
- The Advanced Higher Engineering Science project: a candidate-chosen engineering investigation worth half the course assessment, covering the aim, research, planning, analysis, synthesis, evaluation and report.3Q&A pairs
Area: Mechanisms and structures
- Dynamics with Newton's laws of motion, momentum and impulse, the conservation of momentum, and work, energy and power applied to moving bodies.3Q&A pairs
- Linear kinematics with the equations of motion for uniform acceleration, the analysis of displacement, velocity and acceleration, and the interpretation of motion graphs.3Q&A pairs
- Mechanisms transmitting motion: gear trains and compound gears, velocity ratio and mechanical advantage, the relationship between torque, speed and power, and drive-system efficiency.3Q&A pairs
- Stress, strain and Young's modulus, the tensile test and material properties, and the use of a factor of safety to set a safe working stress.3Q&A pairs
- The analysis of loaded beams: shear force and bending moment, their diagrams along the span, and the role of the second moment of area in resisting bending.3Q&A pairs
- Static equilibrium of structures with the conditions for equilibrium, finding support reactions by taking moments, and resolving the internal forces in pin-jointed frameworks as ties and struts.3Q&A pairs
