Qhov sib piv ntawm qhov yooj yim ntsia hlau jack formula yog txhais raws li qhov piv ntawm ob zaug π multiplied rau qhov ntev ntawm caj npab mus rau lub suab ntawm lub hau thiab yog sawv cev raws li vratio=(2pil)/p or velocity_ratio=(2piLength of lever arm)/Pitch.

Koj ua li cas xam qhov nrawm piv ntawm lub qhov ntsia hlau?

Lab Manual | Txhawm rau xam qhov ua tau zoo ntawm cov ntsia hlau yooj yim jack

  1. Velocity ratio (V. R.): Nws yog qhov piv ntawm qhov nrug (y) txav los ntawm kev siv zog mus rau qhov nrug (x) txav los ntawm kev thauj khoom.
  2. V. R=y/x.

Qhov sib piv ntawm cov ntsia hlau yog dab tsi?

Qhov sib piv ntawm cov ntsia hlau jack =e/l=37.7/(1/6)=226. Txawm hais tias cov xov ntawm cov ntsia hlau tau khaws cia kom huv si thiab zoo greased, tseem yuav muaj kev sib txhuam ntawm cov ntsia hlau thiab ob qho tib si lifting block thiab lub hauv paus phaj.

Vim li cas piv txwv yog dab tsi?

Qhov sib piv nrawm (V. R.) ntawm lub tshuab yog qhov sib piv ntawm qhov kev ncua deb los ntawm kev siv zog rau kev ncua deb ntawm lub load. Formula – Velocity Ratio=nrug txav los ntawm kev siv zog / nrug txav los ntawm kev thauj khoom=y/x Lub nrawm ntawm muab tshuab kuj tuaj yeem txiav txim siab los ntawm kev xav lub tshuab kom zoo tagnrho.

Veocity ratio sib npaug li cas?

Qhov sib piv qhov nrawm (V. R.) ntawm lub tshuab yog txhais raws li qhov piv ntawm qhov nrawm ntawm kev siv zog rau qhov nrawm ntawm lub nra. Hauv lwm lo lus, nws yog qhov piv ntawm kev hloov pauv ntawm kev siv zog rau kev hloov pauv ntawm lub thauj khoom.
