Study Notes
Boolean Algebra
- The Boolean equation A B = Z can be represented by a logic diagram.
Forces and Diagrams
- A free body diagram should include one piece of information: the forces acting on the object.
- A sign hangs from the ceiling by two cables, A and B, with cable A having an original length of 4.5 m and stretching by 0.0013 m.
- Strain in cable A is calculated as 0.0013/4.5.
Flowcharts and Sequences
- A sequence involves checking the seatbelt sensor, and if off, turning on the warning lamp and then the buzzer three times over 1.8 seconds.
- The flowchart would include input/output connections, pin numbers, and delay units.
Forces and Materials
- A force of 15 N mm-2 is applied to a seatbelt strap with a cross-sectional area of 48 mm2.
- The force applied is calculated as 15 x 48 = 720 N.
Pneumatic Circuits
- A pneumatic circuit is used to arrange bottles ready for packaging in a production line.
- The circuit operates by receiving a signal from the microcontroller, which then activates cylinders A and B.
- Air at a pressure of 0.32 N mm-2 is supplied to cylinder B, resulting in an outstroking force of 620 N.
- The area of the piston is calculated as 620/0.32, and the diameter of the piston is calculated accordingly.
Microcontrollers and Programming
- A microcontroller based system is used to detect bottles and count six bottles.
- The program uses a loop to check the input and increment a count, and then switches on a signal when the count reaches 6.
- The program includes a time delay of 500 ms.
- The wiring of the bottle sensor and transistor to the microcontroller is completed with reference to the program.
Electronic Engineering and Sustainability
- An electronic engineer would complete a task such as designing the warning sign's power supply when using solar energy.
- Using LEDs instead of lamps in the warning sign has an economic impact of reducing energy costs.
- Using solar powered LEDs in the warning sign has an environmental impact of reducing carbon emissions.
