Ulwazi Lomkhiqizo: Isitsha se-Hemispherical Sundial
Lesi sitsha senzelwe ukusetshenziswa ne-hemispherical sundial futhi yakhelwe ngokukhethekile izindawo eziwela ku-latitude 30 degrees eningizimu. Indandatho yomkhathizwe ye-sundial kanye nama-gnomons nakho kuklanyelwe ukusebenza ngokuhambisana nalesi sitsha ukuze kuchazwe ngokunembile isikhathi ngokusekelwe endaweni yelanga.
Imiyalo yokusetshenziswa komkhiqizo
- Khetha indawo engenazithiyo view wezulu futhi uyamukela ampukukhanya kwelanga usuku lonke.
- Beka isitsha endaweni eyisicaba, uqinisekise ukuthi isezingeni futhi ivikelekile.
- Faka indandatho yomkhathizwe endishini, uyiqondanise nezimpawu endishini ezibonisa i-latitude engu-30 degrees eningizimu. Qinisekisa ukuthi ihlezi kahle futhi ivikelekile.
- Faka ama-gnomons emigodini esemkhathizwe, uqondanise nezimpawu ezihambisana nosuku lwamanje.
- Linda kuze kube yilapho ilanga lifika endaweni yalo ephakeme kakhulu esibhakabhakeni (emini) futhi ulungise ama-gnomons njengoba kudingekile ukuze ahambisane nesithunzi esidalwe yilanga. Lokhu kuzokuvumela ukuthi unqume isikhathi esifanele ngokusekelwe emakhakheni akwindandatho yomkhathizwe. Usuku lonke, bheka ukunyakaza kwesithunzi futhi ulungise ama-gnomons njengoba kudingeka ukuze uwagcine ehambisana nesithunzi. Lokhu kuzokuvumela ukuthi utshele ngokunembile isikhathi ngokusekelwe endaweni yelanga esibhakabhakeni.
- Uma usuqedile usebenzisa i-sundial, susa ama-gnomons nendandatho yomkhathizwe endishini bese uwagcina endaweni ephephile. Isitsha singashiywa endaweni noma sigcinwe njengoba kuthanda.
