Q1— Section header —

1.1As the pressure in the pipe changes it will cause the plates of t he capacitor to move in and out resulting in the dielectric strength changing the

1.2(4\

1.3monostable multivibrator has one stable state he circuit will flip into the unstable state for a determined period, but will eventually return to the stable state. Such circuit is useful for creating a timing period of fixed duration in

Q2— Section header —

2.1Single axis control (1\

2.2bsolute encoder s are used to measure angular position. Depending on its resolution or accuracy each angular position of the motor shaft will produce a specific output signal.

Q3— Section header —

3.1The potential energy created at point A is low due to the small distance of the outlet from the top of the tank and therefore less pressure is created. The potential energy created at point B is higher

3.2Marks only awarded for correctly connect ed units (10\

3.3Good lubrication Low volatility Low density Low toxic ity Environmental and chemical stability High degree of incompressibility Fire resistance Good heat transfer

Q4— Section header —

4.1Control is the process where a group of elements are connected together to govern the power delivered to an application It is the switching action of a toggle switch to a hardwired complex network of elements or to a hybrid

4.2Pumping glue to a glue gun Pressing body parts Plastic processing machinery Steel making Primary metal extraction applications Automated production lines Machine tool

Q5— Section header —

5.1.1essure Power to the hydraulic pack (2\

5.1.2Not enough oil in the reservoir Leaking seals Loose inlet lines Incorrect oil type Excessive oil temperatures with no o r very low electrical impedance whereas an open circuit is an infinite resistance between two nodes.

About Mechatronic Systems examination preparation

This TVET examination resource can be used as part of a structured revision programme. Past papers are most useful when learners attempt questions independently, work within a realistic time limit, and review their answers afterwards.

How to use this resource for revision

A TVET past examination paper is most useful when it is treated as an active revision exercise. Try the questions yourself before checking the corresponding memorandum. Where you make an error, identify the reason — was it a knowledge gap, a calculation mistake, an interpretation issue, or an examination technique problem?

For stronger examination practice, complete the paper without unnecessary interruptions and keep track of the questions that take the most time. Afterwards, review the memorandum and separate knowledge gaps from mistakes caused by interpretation, calculation, structure, or examination technique.

A practical revision approach

Start by completing the resource without looking at the memorandum. Review incorrect and incomplete answers afterwards and make a short revision list based on the areas that caused difficulty.
