Misalai 4 na tambayoyin hanzarta kusurwa da hanzarta tangential
1. Tayar da ke da radius na santimita 30 tana juyawa tare da saurin kusurwa na 5 rad/s akai-akai2Yaya girman hanzarin tangential na wani wuri wanda yake (a) 10 cm daga gatari (b) 20 cm daga gatari (c) a gefen tayoyin?
Tattaunawa
2. Idan saurin gudu na wani wuri a gefen propeller mai radius na 50 cm shine 2 m/s2, menene saurin kusurwa na propeller?
Tattaunawa
An sani :
Radius (r) = 50 cm = mita 0,5
Hanzarin tangential (a)tan) = 2 m/s2
An tambaya : hanzarta kusurwar propeller
Jawab :
3. Ana hanzarta ƙafar da ke da radius na 20 cm wanda da farko yana hutawa daidai gwargwado. Bayan daƙiƙa 2, ƙafar za ta juya da saurin kusurwa na 10 rad/s. A ƙayyade girman saurin tangential na (a) maki 10 cm daga gatari (b) gefen ƙafafun!
Tattaunawa
An tambaya : hanzarin tangential (a) a r = mita 0,1 (b) a r = mita 0,2
Jawab :
Da farko, ƙididdige hanzarin kusurwa na tayoyin. Yi amfani da tsarin motsi na zagaye mai canzawa iri ɗaya lamba 1:
4. Famfo mai radius na 20 cm, wanda da farko yana juyawa a gudun kusurwa na 20 rad/s, yana tsayawa juyawa bayan daƙiƙa 2. Kayyade girman hanzarin tangential na (a) maki 10 cm daga axis (b) gefen famfo!
