Hidrouliese en pneumatiese stelsels

Module 13

Om ’n hidrouliese stelsel te bou

Fokustaak1:

Om ’n hidrouliese stelsel te bou

[lu 2.3 – 1.13]

  • Gebruik die werkstekening en bou ’n model van ’n hidrouliese stelsel wat aan ’n hefboom gekoppel is.

  • Jy benodig:
  • 1 x 10 mℓ-plastiekspuit
  • 1 x 20 mℓ-plastiekspuit
  • plastiekbuisie (lengte soos benodig)
  • lang spyker
  • geriffelde karton (onthou al die beginsels van versterking)
  • skêr, gom, maskeerband, kleeflint

PROJEK:

DIE TEGNOLOGIESE PROSES

[LU 1.1, 3.2]

  • Gebruik jou kennis van strukture en/of elektronika en/of meganismes en integreer dit met jou kennis en ondervinding van hidrouliese of pneumatiese stelsels om EEN van die volgende situasies op te los. Die probleem moet in terme van ’n TEGNOLOGIESE PROSES opgelos word en in ’n PORTEFEULJE voorgestel word.
  • Vir die PRAKTIESE WERK moet ’n prototipe, so goedkoop as moontlik, gebou word. Hierdie prototipe moet kan funksioneer.
  • Gebruik die assesseringsskale/matrikse om seker te maak of jy aan die vereistes van die proses voldoen.

Situasie I

Jou woonbuurt word geteister deur ’n brommerplaag. In verskeie koerantberigte is die mense van die omgewing gevra om die probleem hok te slaan deur die asblikke toe te hou. Dit is nie so maklik nie. Rondloperkatte wat gedurig die asblikke oopmaak, is een van die groot frustrasies. Die ander groot probleem is die verspreiding van kieme wat hand aan hand met die plaag gaan.

’n Inwoner het tot die slotsom gekom dat hy iets moet ontwerp wat hom in staat stel om die asblik oor ’n afstand oop te maak en wat hom waarsku wanneer die blik oop is.

Situasie II

In die kleedkamers vir gestremdes is die oopmaak van die deur altyd ’n groot probleem. Die gestremdes kan net ’n druk-aksie met hul hand, kierie of rolstoel se wiel uitvoer. Hierdie aksie moet hulle dan in staat stel om die deur oop te maak.

Situasie III

Die plak van posseëls kan baie tydrowend en vermoeiend wees wanneer dit op groot skaal gedoen word. ’n Toestel wat die posseël plak deur die druk van ’n knoppie en aandui dat dit suksesvol voltooi is, kan die probleem oplos.

Stappe van die Tegnologiese Proses wat gevolg moet word:

1. ONDERSOEK

1.1 ANALISE VAN ONTWERPVOORSTEL

  • Kern van die probleem
  • WAT sal ek doen?
  • WIE gaan dit gebruik?
  • WANNEER sal dit gebruik word?
  • WAAR sal dit gebruik word?
  • WAAROM sal dit gebruik word? [LU 1.1]

1.2 ONTWERPVOORSTEL

  • Ontwerp en maak……..wat, vir wie, waar, waarom en wanneer.

1.3 BEPERKINGS EN SPESIFIKASIES

  • Beperkings: Vereistes wat die keuse van die oplossing beperk.
  • Spesifikasies: Sluit beperkings in en word deur leerder self bepaal. Dit is ’n lys van faktore wat bepaal hoe die eindproduk gaan lyk en funksioneer.

2. ONTWIKKELING VAN IDEES

2.1 NAVORSING

  • Navorsing gaan oor die vaardigheid om data te versamel, data te noteer, data te analiseer en besluite volgens verwerkte data te neem.
  • Maak ’n lys van alle inligting wat jy benodig om jou idees te ontwikkel.
  • Hier is ’n paar voorstelle om jou te help.

STRUKTURE:

  • Materiale wat beskikbaar is.
  • Hoe kan die materiale versterk word?
  • Hoe word verskillende materiale gebruik?

why is communication effective
Dakolo Reply
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment

because it helps many people around the world to understand how to interact with other people and understand them well, for example at work (job).

Isn't practices worldwide, be it psychology, be it science. isn't much just a false belief of control over something the mind cannot truly comprehend?

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills

hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities. before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these

continue.. sometimes due to these physical problems..the diagnosis may be misdiagnosed. treatment for autism. well it depends on the severity. since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective
Jharna
results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
