Frictional urovha - chiri "nzvimbo" pakanga wose

Urovha inomuka apo mabasa zvishoma pane vashandi. Uyewo, kuti basa vashandi ipfupi nokuti kuti akatanga itsva, kunyanya zvoga, ano.

The unopinza kuwedzera kwemabasa kuonekwa panguva kudzikira. Izvi zvinoitika kana shoma kugadzirwa mavhoriyamu uye vazhinji zvinobatanidzwa pamusika, ayo vanogumurwa kubva mabasa avo.

Kuti tinzwisise zviri nani pfungwa iyi, funga zvinokonzera uye mhando urovha.

Saka, zvikonzero:

1) nokuti kuti zvekudya achibudiswa svomhu kunoita, uye vagari zvakunokura geometric (asi pano pane "dzinongoitika" kwevanhu kudzora - denda, hondo, njodzi dzinongoitika dzoga);

2) kurasikirwa kumabasa;

3) itsva vasingashandi (vadzidzi, somuenzaniso).

Zviri chokuzvidira, involuntary, STRUCTURAL, cyclical, Isimba rakadini rinogona kubudiswa, chirwere uye frictional urovha. Hazvisi zvose zvayo mhando, asi kakawanda dzinounzwa mune upfumi.

Kwokuzvidira urovha zvinoreva kuti kudzingwa kunoitwa mushandi ari chikumbiro yake. Kudzosera chokuita kuti zvinoderedza kugadzirwa, somugumisiro mudonzvo uri kunze basa. Structural urovha kunoitika apo rutapudzo vamwe maindasitiri uye chimiro nevamwe, kana, panguva reorientation makambani vavo yezwi chigadzirwa itsva ndewe kuda kudzidzisazve revashandi kana kuderedza zvimwe uye vakabhadhara vatsva.

Cyclical urovha kunoitika kana kutsiviwa nebasa zvinogara. Zvinonzi dzichichinja ari papi uye nziyo. Yakavanzwa vari navavezi, varimi uye vashandi, avo vanoshanda havasi yakazara. A chirwere urovha - uye kugara guru.

Frictional urovha - imwe mismatch nguva mushandi runoita kubva zvebhizimisi kune mumwe. Zvinoitawo kunoitika apo kutamira kubva basa mumwe, kubva bhizimisi mumwe. Frictional urovha - zvinokwanisika kuudza, vakawanda zvisingadiwi mhando kwemabasa. Vanhu vari kutsvaka uye achitarisira kushanda, kutama uchibva panzvimbo imwe neimwe, kutamira kune basa yemapurisa mumwe.

Frictional urovha - ndiko kushaya nebasa sezvazviri zvakafanira basa mufambo. Sezvo zvinoitika pamwe yekupindurwa munzanga yacho mushandi. mamiriro ezvinhu akawanda anogona kunzi kuti tinzwisise zviri nani pane frictional urovha. mienzaniso:

- kudzingwa kuitira kuti kuchinja basa;

- mushandi kunoita kuti imwe nzvimbo uye, naizvozvovo, anofanira kusiya yaimbova nzvimbo;

- chido kuti kune imwe kambani imwe chete dzakagadzirirwa.

Urovha ane zveupfumi nemigumisiro:

1) bhuku chakakomba National chigadzirwa shure zvichiita;

2) kodzero nomushandi pamwe nguva yakarasika.

Panguva zvepanyama mwero kwemabasa anogona kutaura zvinobudirira basa, izvo zvinoreva mumwe ukama pakati urovha uye basa. Tinogona kutaura kuti kumusika gadziriro contraindicated sezvo urovha uye basa zvizere.
