2 Musimboti wesimba rekushanda Simba risingachengetedzi Kufamba mundege yakatsamira nekukakavadzana - Matambudziko nemhinduro
1. Chivharo chinotsvedza pasi chakarerekera nekukweshana. Kumhanya kwechivharo chii kana chivharo charova pasi? Chiyero chekukweshana kwekinetic i0.4. Kukurumidza kunokonzerwa negiravhiti i10 m/s 2.
Zvinozivikanwa:
Kureba kwekutanga (h)o) = 6 m
Kureba kwekupedzisira (h t ) = 0 m
Kumhanya kwekutanga (vo o ) = 0 (block pakutanga yasara)
Kukweshana kwekinetic (μ k ) = 0.4
Basa rinoitwa mumaitiro ethermodynamic - matambudziko nemhinduro
1. Gasi rakakodzera rinomanikidzwa kubva padunhu 1 kuenda padunhu 2 sezvakaratidzwa mugirafu riri pazasi. Sarudza basa rinoitwa negasi.
mhinduro
1 litre = 0.001 m3
Zvinozivikanwa:
Kumanikidzwa 1 (P 1 ) = 10 kPa = 10,000 Pa = 10,000 N/m 2
Kumanikidzwa 2 (P 2 ) = 20 kPa = 20,000 Pa = 20,000 N/m 2
Kubonderana uye kuchengetedzwa kwesimba remakanika - mapurobhu nemhinduro
1. Zvinhu zviviri zvine huremu hwakafanana , m 1 = m 2 = 0.5 kg zvakadonhedzwa kubva pahurefu hwakafanana sezvakaratidzwa mumufananidzo uri pazasi. Radius yedenderedzwa i 1/5 m. Kubonderana pakati pezvinhu zvese zviri zviviri kwakanyatsosimba. Sarudza kumhanya kwechinhu chimwe nechimwe mushure mekubonderana. Kukurumidza kunokonzerwa negiravhiti i 10 m/s 2.
Zvinozivikanwa:
Huremu hwechinhu (m) = m1 = m2 = 0.5 kg
Kureba kwekutanga (h 1 ) = 1/5 m
Kureba kwekupedzisira (h 2 ) = 0 ( hwaro hwenzira )
Kufamba kweMomentum Impulse uye Projectile - Matambudziko neMhinduro
1. Bhora re 0.2-kg richapinzwa mugomba C, sezvakaratidzwa mumufananidzo uri pazasi. Munhu anorova bhora anorova musekondi 0.01 uye nzira yeBC yakafamba musekondi imwe chete. Sarudza hukuru hwesimba kuitira kuti bhora rigone kupinzwa mugomba C. Kukurumidza kunokonzerwa negiravhiti ndeye 10 m/s 2.
Zvinozivikanwa:
Angle (θ) = 60 o
Huremu hwebhora (m) = 0.2 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Nguva yenguva (Δt) = 0.01 masekondi
Kufamba kwemutsetse kusingaenzaniswi - matambudziko nemhinduro
1.
Tafura iri pamusoro inoratidza data rezvinhu zvitatu zvinofamba daro rakafanana nekumhanya kwakasimba.
Ndeipi kumhanya kwekupedzisira kwechinhu P uye kumhanya kwekutanga kwechinhu Q?
Dzidziso yeKinetic yemagasi uye mutemo wekutanga wethermodynamics - matambudziko nemhinduro
1. Magasi akakodzera ari mumudziyo une vhoriyamu yemarita mana uye kumanikidzwa kwawo kuri 3 atm (1 atm = 10 5 Nm -2 ). Magasi akakodzera anopiswa nekumanikidzwa kunogara kuripo kubva pa27 o C kusvika 87 o C. Kugona kupisa kwegasi i9 JK -1 . Ndeipi vhoriyamu yekupedzisira yemagasi uye shanduko yesimba remukati memagasi?
mhinduro
Maitiro eIsobaric (kumanikidzwa nguva dzose)
Zvinozivikanwa:
Huwandu hwekutanga hwegasi (V 1 ) = 4 malita
Kutenderera kwemiviri yakaoma - matambudziko nemhinduro
Nguva yesimba
1. Masimba matatu anoshanda padanda rine hurefu hwemamita matanhatu, sezvakaratidzwa mumufananidzo uri pazasi. Chii chinonzi net torque inotenderedza danda pamusoro penzvimbo O se axis yekutenderera?
Zvinozivikanwa:
Mutsetse wekutenderera panzvimbo yeO.
Simba 1 (F 1 ) = F
Daro riri pakati pemutsetse wekuita weF 1 ne axis of rotation (r 1 ) = mamita matatu
Zvitubu zvakatevedzana uye zvakafanana - matambudziko nemhinduro
1. Chinhu che 160-gram chinonamira pamucheto wechitubu uye kuchinja kwehurefu hwechitubu i4 cm. Chii chinonzi kuchinja kwehurefu hwezvitubu zvitatu zvakabatana zvakatevedzana uye zvakafanana , sezvakaratidzwa mumufananidzo uri pazasi?
Zvinozivikanwa:
Kuchinja kwehurefu hwechitubu (Δx) = 4 cm = 0.04 m
Huremu (m) = magiramu makumi mana = 0.16 kg
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Maitiro ekufamba kwese kwese - matambudziko nemhinduro
1. Pulley ine nguva yekusashanda I = 2/5 MR 2 ine huremu hwe2-kg. Kana nguva yesimba papulley iri 4 Nm saka chii chinonzi linear acceleration yepulley. Kukurumidza kunokonzerwa negravity g = 10 ms -2.
Inozivikanwa :
Nguva yekusashanda kwepulley (I) = 2/5 MR 2
Huremu hwepulley (M) = 2 kg
Nguva yesimba (τ) = 4 Nm
Maitiro ezvikamu - matambudziko nemhinduro
1. Chinhu A chine huremu hwe6-kg uye chinhu B chine huremu hwe4-kg chakabatanidzwa netambo uye chakadhonzwa nesimba reF = 60 N, sezvakaratidzwa mumufananidzo uri pazasi. Coefficient yekinetic friction pakati pepasi nezvinhu zvese i0.5 (tan θ = ¾). Kukurumidza kunokonzerwa negiravhiti i10 m/s 2 . Simba rekumanikidzana rinokura sei?
Zvinozivikanwa:
Huremu hwechinhu A (m)A) = 6 kg
Huremu hwechinhu B (m B ) = 4 kg
Simba (F) = 60 Newton
