Simba rekushanda nesimba Simba risingachengetedzi kufamba mundege yakatsamira nekukakavadzana - Matambudziko nemhinduro

2 Musimboti wesimba rekushanda Simba risingachengetedzi Kufamba mundege yakatsamira nekukakavadzana - Matambudziko nemhinduro

1. Bhokisi rinotsvedza pasi ndege yakatsamira nekukweshana. Chii chinonzi bhokisi velocity bhokisi rinorova pasi riini? Chiyero che kukweshana kwekinetic i0.4. Kukurumidza kwesimba nekuda kwegiravhiti i10 m/s².

Zvinozivikanwa:

Kureba kwekutanga (h)_o) = 6 m Simba rekushanda nesimba, simba risingachengetedzi, kufamba kwakanangana nekukweshana - matambudziko nemhinduro 1

Kureba kwekupedzisira (h)_t) = 0 m

Kumhanya kwekutanga (v)_o= = 0 (vhara pakutanga pakuzorora)

Kukweshana kwekinetic (μ)_k= = 0.4

Basa rinoitwa mumaitiro ethermodynamic - matambudziko nemhinduro

1. Ku gasi rakanaka inodzvanywa kubva panhamba 1 kuenda panhamba 2 sezvakaratidzwa pagirafu iri pazasi. Sarudza kuti basa zvinoitwa negasi.

mhinduro

1 litre = 0.001 m³

Zvinozivikanwa: Basa rakaitwa mumaitiro ethermodynamic - matambudziko nemhinduro 1

Pressure 1 (P)₁) = 10 kPa = 10,000 Pa = 10,000 N/m²

Kumanikidzwa 2 (P)₂) = 20 kPa = 20,000 Pa = 20,000 N/m²

Kubonderana uye kuchengetedzwa kwesimba remakanika - mapurobhu nemhinduro

1. Zvinhu zviviri zvakafanana uremu, m₁ = m₂= 0.5 kg yakadonhedzwa kubva pakukwirira kwakafanana sezvakaratidzwa mumufananidzo uri pazasi. Radiyumu yedenderedzwa i 1/5 m. Iyo kudhumhana pakati pezvinhu zvese zviri zviviri panonyatsonamira. Sarudza kuti velocity chinhu chimwe nechimwe mushure mekubonderana. Kuwedzera nekuda kwegiravhiti iri 10 m/s².

Zvinozivikanwa:

Huremu hwechinhu (m) = m₁= m₂ = 0.5 kg Kubonderana uye kuchengetedzwa kwesimba remakanika - mapurobhemu nemhinduro 1

Kureba kwekutanga (h)₁) = 1/5 m

Kureba kwekupedzisira (h)₂= = 0 (hwaro hwenzira)

Kufamba kweMomentum Impulse uye Projectile - Matambudziko neMhinduro

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. Kuwedzera nekuda kwegiravhiti iri 10 m/s².

Zvinozivikanwa: Kufamba kwesimba, kusundidzira uye kufamba kwepfuti - matambudziko nemhinduro 1

Angle (θ) = 60^o

Misa yebhora (m) = 0.2 kg

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s²

Nguva yenguva (Δt) = 0.01 masekondi

Tafura iri pamusoro inoratidza data rezvinhu zvitatu zvinofamba daro rakafanana pa kukurumidza nguva dzose.

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 huwandu hwemarita mana uye kumanikidzwa kwawo kuri 3 atm (1 atm = 10⁵ Nm^-2). The magasi akakodzera inopisa nekumanikidzwa kunogara kuripo kubva pa27^oC kuti 87^oC. The kupisa simba yegesi i9 JK^-1Chii chinonzi huwandu hwekupedzisira hwemagasi uye shanduko yesimba remukati memagasi?

mhinduro

Maitiro eIsobaric (kumanikidzwa nguva dzose)

Zvinozivikanwa:

Huwandu hwekutanga hwegasi (V)₁) = marita mana

Kutenderera kwemiviri yakaoma - matambudziko nemhinduro

The mnguva yesimba

1. Masimba matatu anoshanda padanda rine hurefu hwemamita matanhatu, sezvakaratidzwa mumufananidzo uri pazasi. Chii chinonzi torque yemagetsi inotenderera danda rakatenderedza poindi O se axis yekutenderera?

Zvinozivikanwa: Kutenderera kwemiviri yakaoma - matambudziko nemhinduro 1

Mutsetse wekutenderera panzvimbo yeO.

Simba 1 (F)₁) = F

Daro riri pakati pemutsetse wekuita waF₁ne axis yekutenderera (r)₁) = mamita makumi matanhatu

Zvitubu zvakatevedzana uye zvakafanana - matambudziko nemhinduro

1. Chinhu che 160-gram chinonamira pamucheto wechitubu uye kuchinja kwehurefu hwechitubu i4 cm. Chii chinonzi kuchinja kwehurefu hwetatu? zvitubu zvakabatana zvakatevedzana uye zvakafanana, sezvakaratidzwa mumufananidzo uri pazasi?

Zvinozivikanwa:

Kuchinja kwehurefu hwechitubu (Δx) = 4 cm = 0.04 m Zvitubu zvakatevedzana uye zvakafanana - matambudziko nemhinduro 1

Misa (m) = magiramu 160 = 0.16 kg

Kuwedzera nekuda kwegiravhiti (g) = 10 m/s²

Maitiro ekufamba kwese kwese - matambudziko nemhinduro

1. Pure ine nguva ye inertia Ini = 2/5 MR² ine huremu hwe2 kg. Kana nguva yesimba Papulley pane 4 Nm saka chii chinonzi linear acceleration yepulley. Kukurumidza kunokonzerwa negravity g = 10 ms^-2.

Inozivikanwa : Maitiro ekufamba kwese kwese - matambudziko nemhinduro 1

Nguva yekusashanda kwepulley (I) = 2/5 MR²

Misa yepulley (M) = 2 kg

Nguva yesimba (τ) = 4 Nm

Maitiro ezvikamu - matambudziko nemhinduro

1. Chinhu A chine huremu hwe6-kg uye chinhu B chine uremu ye4-kg yakabatana netambo uye yakadhonzwa nesimba reF = 60 N, sezvakaratidzwa mumufananidzo uri pazasi. kukweshana kwekinetic pakati pepasi nezvinhu zvese zviri zviviri i0.5 (tan θ = ¾). Kuwedzera nekuda kwegiravhiti iri 10 m/s²Simba rekumanikidzwa rakakura sei?

Zvinozivikanwa:

Huremu hwechinhu A (m)_A) = 6 kg Maitiro ezvikamu - matambudziko nemhinduro 1

Huremu hwechinhu B (m_B) = 4 kg

Simba (F) = 60 Newton
