Umthetho legolide ubucukubhede.

Nkqu kumaxesha amandulo, xa kusetyenziswa iindlela ezilula (esangweni block lever njalo njalo.), A inkalo omhle aba matshini wafunyanwa. Ndafumanisa ukuba zonke iintshukumo e iindlela ezilula sibe nolwalamano elithile imikhosi ephuhlisa imoto. Kufuneka kuqatshelwe ukuba intshukumo eziphelweni 2 yindlela elula apho amandla kusoloko kukho lobudlelwano elinemikhosi ziyasetyenziswa kwiinjongo.

Amandla, kuchaphazela ilungelo ingalo lever yi amaxesha n incinane ungamandla enza izinto kwigxalaba lasekhohlo. Ngako oko, intshukumo kwengalo yasekunene (s2) kumaxesha n ngaphezu intshukumo kwengalo yasekhohlo (S1).

Umzekelo, ukuba ukwenzela ukugcina sokunqika ukulingana, ubukhulu amandla F2 kufuneka n ezincinane amaxesha ngaphezu ubukhulu bezinto F1 amandla. Kulo mzekelo, xa sokunqika esijikeleziswa, intshukumo isiphelo s2 yesibini iya kuba n amaxesha ezinkulu kuno intshukumo S1 ka ekupheleni yokuqala. Ukuba yunithi a kabini, ngoko ke eneneni lulwahlulo efanayo phakathi imikhosi ukuba incamathele iintambo ukuba isilonda zombini iyunithi uze uyigcine imo lizama, kunye nentshukumo ngentambo iphela xa iyunithi iyajikeleza. Njengoko ukubaluleka kwale lungiselelo ngazo zabaxwa, ngokuba mnandi kakhulu, "ulawulo yegolide ubucukubhede".

Ukusebenzisa notation aye wangena, ubucukubhede ulawulo segolide lungabonakaliswa yi ifomula:

S1 / s2 = F2 / F1

okanye S1 * F1 = s2 * F2.

Emva koko, kwabakho ingxaki chu yeendidi iintshukumo kunye nohlobo koomatshini ezazisetyenziswa ubucukubhede. Kwathi ke ukuba umthetho yegolide ukukhanda azisoloko igcina ukufaneleka kwayo ngendlela elula. Noko ke, xa kuba nzima iintlobo umatshini kunye iintlobo zeentshukumo, bobabini eyenzekayo nokuntsonkotha ulawulo yegolide ubucukubhede. Ngenxa yoko, phantsi amatyala alo impembelelo yaqala ukuna nzima. Kufuneka kuqatshelwe ukuba ulawulo yegolide ukukhanda yaba isiseko ukuvela iimbono ezahlukeneyo malunga namandla kunye nomsebenzi. Kulo mzekelo, umthetho lowo wokuqala, ekuqulunqeni elula yomthetho yolondolozo amandla, ukufaneleka okuqhubekayo kuzo zonke iziganeko zendalo.

Ukusetyenziswa "umthetho yegolide"

Lo mgaqo usasebenza kuphela kwimeko sesindululo efanayo oomatshini ezilula (okanye ukukhawulezisa kancinane). Ngokomzekelo, xa ijikelezwe ibloko kabini, kukho intshukumo ye iziphelo iintsontelo phezu s1 imigama kunye s2, ezo nxeba phakathi zaziibloko weerediyasi R1 R2 kwaye ukhuselekile kunye. Ezi imigama ke ngokomlinganiselo radii R1 / R2 = S1 / s2.

Ngoko ke, ukuba ulawulo segolide sele yokungxamiseka ibloko kabini, kufuneka ukuhlangabezana iimeko ezithile ilandelayo: F1 / F2 = R2 / R1.

Kulo mzekelo, yenzeka kuvuselele imikhosi F1 kunye F2. Ngoko ke, lo matshini kufuneka enze, okanye isindululo iyunifomu, okanye uhlale ukuphumla. Nakuba kunjalo, ukwenzela ukuba uqale kwibhloko kabini, ukuba aphume eseleyo. Ukuza kuthi ga ngoku, nayiphi na amandla, umzekelo, ukuya F1, ufuna ukongeza amandla f. Intshukumo okwenzeka emzimbeni, iza kukhawuleziswa.

lwemali kazwelonke

Lwemali kazwelonke icandelo mali, nto leyo isenza i-National Bank okanye urhulumente ngenjongo yokuba ukusetyenziswa kwayo kuloo mmandla SoNA okanye kwamanye amazwe. Oku kusetyenziswa zombini kwi exchange yoqoqosho lwehlabathi, ngokunjalo kwezinye iindawo, apho isekelwe kwiintlawulo zekheshi.

Collection evela kwintengiso lwemali

Umbuzo azinikele ukuqaliswa kwe-lokuqokelela kunye olu hlobo lomsebenzi njengoko intengiso imali amazwe ngemali ezinkozo, livakale ukuba ukho na kuluntu, ngaphandle kokuba uyakwazi enokuthelekiswa unyulo igunya elongamileyo kunye ekuqaleni nokusebenza lepalamente olawulo asanda kunyulwa. Njengoko inani elikhulu izimvo ezahlukeneyo neengcali ngokubhekiselele kwesi ezintsha, i-National Bank linyanzelekile ukuba ngenkuthalo ukwenza iphulo lolwazi phakathi kwabantu karhulumente. Ngaloo ndlela, uya kuchaza abantu imithetho ethile nesigama eziya kuba luncedo kwixesha elizayo yonke njengelungu lombutho woluntu.
