Zvechokwadi unoziva magirazi akati sandara 🙂 Usati waenda kuchikoro, ungangove wakapedza nguva yakareba uchitarisa girazi rako, uchitarisa kana chiso chako chaive chakanaka kana kuti chakanaka 😀 Magirazi chishandiso chiri nyore chekuona chatinowanzo shandisa zuva nezuva.
Tsanangudzo yeGirazi reNdege
Muhupenyu hwezuva nezuva, magirazi eplane anowanzonzi magirazi. Kana munhu akati "girazi," anowanzoreva girazi replane. Mufizikisi, unofanira kuati magirazi eplane kuti usiyanise magirazi akakombama ( magirazi akakombama uye akakomberedzwa ).
Girazi replane igirazi rine nzvimbo yakati sandara, apo imwe yenzvimbo dzacho dzakaputirwa nesimbi inopenya kuitira kuti nzvimbo yegirazi yakati sandara igone kuratidza chiedza chinodarika 95 muzana chinorirova. Kana ukavhenekera tochi pamusoro pegirazi, girazi rinoratidza chiedza chetochi kuitira kuti maziso ako apenye kana chiedza chetochi chinopenya chichirova maziso ako. Kusiyana neizvi, kana ukamira pamberi pegirazi masikati, chiso chako chinovhenekera chiedza chezuva pamusoro pegirazi uye panguva imwe chete, girazi rinodzosera chiedza kwauri. Kana ukamira pamberi pegirazi usiku, chiso chako chinovhenekera chiedza kubva parambi remagetsi pamusoro pegirazi uye panguva imwe chete, girazi rinodzosera chiedza kubva parambi remagetsi kwauri.
Sei chiso chako chichionekwa mugirazi uye mufananidzo uyu unoumbwa sei?
Mvuri
Tarisa muenzaniso wekuumbwa kwemufananidzo wechinhu negirazi sezvakaratidzwa pamufananidzo uri kurudyi. Chinhu (chegirini) chiri pamberi pegirazi. Chinhu chacho chinoratidza chiedza chakawanda. chiedza chemwenje yakananga pamusoro pegirazi asi inoratidzwa semaranzi maviri matete echiedza kana maranzi maviri. Maranzi maviri anorova pamusoro pegirazi anoonekwa nepamusoro pegirazi, uko mutemo wekuratidzira chiedza inoshanda pakuratidzwa kwemwaranzi mbiri. Chiedza chinouya 1 yakatwasuka kana kuti inogadzira kona yemadhigirii makumi mapfumbamweo nemutsetse wakajairika (mutsetse wakajairika = mutsetse wekufungidzira wakatarisana nepamusoro pegirazi iro chiedza chinopfuura napo) nokudaro zvichienderana nemutemo wechiedza, mwaranzi 1 inoonekwa zvakare yakatwasuka kana kuti ichiumba kona yemadhigirii makumi mapfumbamweo ine pamusoro pegirazi. Chiedza chinouya 2 kugadzira angle yemadhigirii makumi mapfumbamweo dengan mutsetse wakajairika Saka, zvichienderana nemutemo wekuratidzira chiedza, mwaranzi wechipiri unooneka unoumbawo kona ye30o nemitsetse yakajairika.
Chiedza chinobva kuna P chichienda kugirazi hachipindi mugirazi asi chinoonekwa. Kana chiedza chikaonekwa negirazi, divi rechiedza chinoratidzwa rinoita serinobva kuna P'. Kana chinhu chacho chikatsiviwa netochi, chiedza chinoburitswa netochi chinoonekwawo negirazi. Ziso remuoni, iro rinongoona kuratidzwa kwetochi chete uye risingazive kuti chiedza chacho chiedza chinoonekwa, rinoona sekunge chiedza chetochi chakabva kuna P'. Mutsetse une madotsi uri mumufananidzo unomiririra "nzira" yechiedza chiri kuseri kwegirazi uye P' mufananidzo wechinhu chacho. Nekuti chiedza hachipindi mugirazi rakati sandara kana kupfuura neseri kwegirazi, mufananidzo waP' ndiwo mumvuri chaiwo kana chirotoKana ukaisa skrini panzvimbo P, hapana mumvuri wechinhu uchaonekwa pachidzitiro.
Muenzaniso wezvinetso
1. Tarisa mufananidzo!
Chinhu chinoiswa 4 cm pamberi pegirazi replane, ipapo kukwirira kwemufananidzo uye daro remufananidzo kubva pagirazi zvinoteerana...
A. 1 cm uye 4 cm
B. 4 cm uye 1 cm
C. 3 cm uye 5 cm
D. 4 cm uye 4 cm
Kukurukurirana
Mugirazi rakati sandara, kukwirira kwemufananidzo = kukwirira kwechinhu uye daro remufananidzo = daro rechinhu.
Kana kukwirira kwechinhu = 1 cm saka kukwirira kwemumvuri = 1 cm.
Kana daro rechinhu = 4 cm saka daro remufananidzo = 4 cm.
Saka kukwirira kwemufananidzo uye daro remufananidzo kubva pagirazi rakati sandara i1 cm uye 4 cm zvichiteerana.
Mhinduro chaiyo ndiA.
2. Hunhu hwemufananidzo unoumbwa negirazi rakati sandara ndehwekuti...
A. yakatwasuka, saizi yakaenzana
B. yakatwasuka, yakaderedzwa
C. yakatwasuka, yakakura
D. yakapindurwa, yakakura
Kukurukurirana
Magirazi akatsetseka anowanzo shandiswa kuratidzira. Mufananidzo unogadzirwa negirazi rakatsetseka wakamira uye saizi yakaenzana.
Mhinduro chaiyo ndiA.
