Faahfaahinta casharka

Natiijada casharka

Waxaan aqoonsan karaa levers-ka (levers) oo waxaan sharxi karaa ujeeddadooda iyo sida ay u shaqeeyaan.

Hordhac

Darsigani wuxuu ku saabsan yahay levers (levers) iyo sida ay u shaqeeyaan. Waa inaad hore u garanaysid fikradaha guud ee xoogga (force) iyo dhaqdhaqaaqa. Soo dhawoow, aan wada bilowno!

Muuji qoraalka
Levers can multiply a small force into a larger force. Levers can multiply a small movement into a larger movement. There are different types of lever, each with the pivot in a different position.

Imtixaannada

  1. 1. Waa kuwee kuwan soo socda kuwa u shaqeeya sida levers (levers)?

    • Jawaabta saxda ah:gaari-gacmeed (wheelbarrow)
    • maqas (scissors)
    • gogo (springs)
    • xadhko (ropes)
    • garaashka isteerinka (steering wheel)

  2. 2. Maxay tahay sababta ay u fududahay in la xakameeyo baaskiil leh gacmo **ballaadhan** marka loo eego midka leh gacmo cidhiidhi ah?

    • gacmuhu waxay noqon doonaan kuwo ka fiican
    • Jawaabta saxda ah:xoogga shaqada (effort force) wuxuu ka fogaan doonaa meesha wareega (pivot)
    • xoogga shaqada (effort force) wuxuu u dhowaan doonaa meesha wareega (pivot)
    • waxay yihiin kuwo hawo fiican u leh
    • meesha wareega (pivot) waxay u dhowdahay xarunta

  3. 3. Maxay tahay sababta uu spanner-ku u shaqeeyo sidii kordhiyaha xoogga (force multiplier)?

    • Qabashadu waxay si adag u haysaa boolkaha si uusan u siibin.
    • Jawaabta saxda ah:Xoogga shaqada (effort force) wuxuu ka fog yahay meesha wareegga (pivot) marka loo eego xoogga culeyska (load force).
    • Xoogga shaqada wuxuu ka dhow yahay meesha wareegga marka loo eego xoogga culeyska.
    • Gacantu waxay ka dhigtaa spanner-ka mid fudud in la qabsado sidaas darteed waxaa soo baxa xoog weyn.

  4. 4. Waa maxay weedhaha saxda ah marka loo isticmaalayo faashad (screwdriver) si loo furo daasad rinji ah?

    • Jawaabta saxda ah:Faashadu waxay u shaqeysaa sidii kor-u-qaade xoog (force multiplier).
    • Xoogga culeysku (load force) wuxuu aad ugu dhow yahay meesha wareegga (pivot).
    • Xoogga dadaalku (effort force) wuxuu aad ugu dhow yahay meesha wareegga (pivot).
    • Meesha wareeggu (pivot) waa cidhifka daasadaha rinjiga.
    • Xoogga dadaalka iyo xoogga culeysku waa inay isku mid yihiin oo iska soo horjeedaan.

  1. 1. Xaggee ayay tahay meesha uu ku yaallo pivot-ka (barta wareegga) ee wheelbarrow-ka (gaari-gacmeedka)?

    • meesha carrada la saaro
    • meel u dhow gacmaha lagu qabsado
    • meesha uu shaaggu taabto dhulka
    • Jawaabta saxda ah:xarunta shaagga

  2. 2. Jaantusku wuxuu muujinayaa albaab furan. Bal yee hadal kee ayaa sax ah?

    • Xoog yar ayaa loo baahan yahay si loo xiro albaabka oo lagu riixo A halkii laga riixi lahaa B.
    • Jawaabta saxda ah:Xoog yar ayaa loo baahan yahay si loo xiro albaabka oo lagu riixo B halkii laga riixi lahaa A.
    • Xoog isku mid ah ayaa loo baahan yahay si loo xiro albaabka oo lagu riixo A iyo B.
    • Albaabka waxaa ugu fudud in la xiro marka lagu riixo meel aad ugu dhow qabsashada (hinges).

  3. 3. Waa maxay ereyga loo isticmaalo lever-ka (lever) soo saara xoog culus (load force) ka weyn xoogga shaqada (effort force) ee la adeegsaday?

    • soo-saare xoog (force producer)
    • kordhiye xoog (force increaser)
    • Jawaabta saxda ah:badhiye xoog (force multiplier)
    • ku-dar xoog (force adder)

  4. 4. Jaantusku wuxuu muujinayaa winch loo isticmaalo in lagu jiido xadhig. Winch-ka waxaa lagu shideeyaa iyadoo la jiidayo gacanta hareeraha pivot-ka dhexda. Waa maxay sifada ka dhigeysa lever-kan mid kor u qaada xoogga (force multiplier)?

    • Wuxuu si fudud u wareegaa.
    • Jawaabta saxda ah:Xoogga shaqada (effort force) waxaa lagu dabaqaa meel fog oo ka fog pivot-ka.
    • Xoogga shaqada waxaa lagu dabaqaa meel u dhow pivot-ka.
    • Xoogga culeyska (load force) waxaa lagu soo saaraa meel u dhow pivot-ka.
    • Xoogga culeyska waxaa lagu soo saaraa meel fog oo ka fog pivot-ka.

  5. 5. Sidee loo kordhin karaa xoogga culeyska (load force) ee soo saara birta culus (crowbar)?

    • Jawaabta saxda ah:kordhinta xoogga dadaalka (effort force)
    • kordhinta masaafada u dhaxaysa xoogga dadaalka iyo meesha wareega (pivot)
    • yaraynta masaafada u dhaxaysa xoogga dadaalka iyo meesha wareega
    • kordhinta masaafada u dhaxaysa xoogga culeyska iyo meesha wareega
    • yaraynta masaafada u dhaxaysa xoogga culeyska iyo meesha wareega
