Fomura yekudzungudza yeHarmonic yependulum iri nyore

Mienzaniso yemibvunzo nemafomura ekutenderera kweharmonic kwe pendulum iri nyore

Kudengenyeka kuri nyore kweharmonic

1. Chinhu chinodedera nefrequency ye5 Hz munzira yekuruboshwe-kurudyi. Chinhu chinotanga kufamba kubva panzvimbo yacho yekuenzanisa kuenda kurudyi. Nguva inodiwa kuti usvike panzvimbo yekurudyi kagumi nerimwe i….

1. 2,05
2. 2,20
3. 2,25
4. 2,50

Kukurukurirana
Zvinozivikanwa kuti:
Kakawanda (f) = nhamba yekudedera pasekondi = 5 Hz
Nguva (T) = nguva yekuita vibration imwe chete = 1/f = 1/5 = 0,2 masekondi
Akabvunzwa: Nguva inodiwa kuti usvike panzvimbo chaiyo kagumi nerimwe ndeye….
Mhinduro:
Maitiro ekufamba kwechinhu (1 vibration): B → C → B → A → B
Munguva yekuzununguka kamwe chete, chinhu chinoita mafambiro mana, anoti B kusvika C, C kusvika B, B kusvika A, A kusvika B.
Nguva inodiwa kuti uite kufamba kamwe chete imasekondi 0,2 / 4 = masekondi 0,05.

Saka nguva inodiwa kuti usvike panzvimbo chaiyo (C) kagumi nerimwe = (10 x 0,2 seconds) + 0,05 seconds = 2 seconds + 0,05 seconds = 2,05 seconds.

2. Chitubu chinoturikwa nemutoro wodedera. Kuti frequency yekudedera ipetwe kaviri frequency yekudedera yekutanga, huremu hwemutoro hunochinjwa kuita...

1. kaviri uremu hwemutoro wekutanga
2. uremu hwemutoro hwepakutanga hwakapetwa kana kana
3. hafu yehuremu hwemutoro wekutanga
4. chikamu chimwe muzvina chehuremu hwemutoro wekutanga

Kukurukurirana
Fomura yekuwanda kwekutenderera kwechitubu:
Information :
f = frequency, k = spring constant, m = huremu hwemutoro
Kuwanda (f) kwekudengenyeka kwechitubu kana k = 1 nguva, m = 1 nguva:
Kuti frequency (f) yekuzununguka kwechitubu ive kaviri, huremu (m) hunochinjwa kuita 0,25 times kana 1/4 times:

Pendulum iri nyore

3. Mapendulum maviri ari nyore ari panzvimbo mbiri dzakasiyana. Kureba kwetambo yependulum yechipiri kwakapetwa ka0,4 kupfuura tambo yependulum yekutanga, uye kukurumidza kunokonzerwa negiravhiti panzvimbo yependulum yechipiri kwakapetwa ka0,9 kupfuura kukurumidza kunokonzerwa negiravhiti panzvimbo yependulum yekutanga. Chiyero chefrequency yependulum yekutanga nefrequency yependulum yechipiri nde….

1. 2/3
2. 3/2
3. 4/9
4. 9/4

Kukurukurirana
Zvinozivikanwa kuti:
Kureba kwetambo yekutanga yependulum (l)₁= = 1
Kureba kwetambo yechipiri yependulum (l)₂) = 0,4 (l)₁) = 0,4 (1) = 0,4
Kukurumidza kunokonzerwa negiravhiti panzvimbo yependulum yekutanga (g₁= = 1
Kukurumidza kunokonzerwa negiravhiti panzvimbo yechipiri yependulum (g₂) = 0,9 (1) = 0,9
Akabvunzwa: Kuenzanisa kwehuwandu hwependulum yekutanga (f)₁) nekakawanda ke pendulum yechipiri (f₂)
Mhinduro:
Kuwanda kwependulum yekutanga (f)₁):
Kuwanda kwependulum yechipiri (f)₂):
Kuenzanisa kwehuwandu hwependulum yekutanga (f)₁) nekakawanda ke pendulum yechipiri (f₂):

4. Mutoro unoturikwa patambo uye unotendeutswa kuitira kuti uite kufamba kuri nyore kweharmonic nefrequency ye0,5 Hz. Kana tambo ikatambanudzwa kusvika paurefu hwayo hwepakutanga ka4, nguva yacho inova….

1. ¼ sekondi
2. ½ sekondi
3. 2 detik
4. 4 detik

Kukurukurirana
Zvinozivikanwa kuti:
Kakawanda kwePendulum (f) = 0,5 hz
Akabvunzwa: Ndeipi nguva (T) yependulum kana kureba kwetambo (l) kwakapetwa ka4 kupfuura kureba kwayo kwekutanga
Mhinduro:
Nguva yekutanga ye pendulum:
Kureba kwekutanga kwetambo:
Kana tambo yacho yakatambanudzwa kusvika pahurefu hwayo hwepakutanga hwakapetwa ka4:
Saka nguva ye pendulum ndeiyi:
Nguva ye pendulum imasekondi mana.
