Tlhokomeliso: Hol ke karolo e matla ea tšireletso. E tlameha ho sebelisoa kopanong e nang le li-curve tsa matla tsa matla. E tsoa ho boiphihlelo le ka lebaka. Ke boleng ba bosholu bo thehiloeng mojaro o phahameng o sebetsang.

Ha moroalo o phahameng oa static o tsejoa, mokhoa oa ho bala o le tjena:
1) Moroalo o matla oa ho sebetsa ka bongata ba moea o mongata oa moea
Axial Force Fa = Q + a + o + g
Nako e feteletseng M = q × hoox + a × r -
2) Ho sa tsotellehe lebotho la moea, nahana ka mojaro oa mojaro oa liteko tsa 25%
Axial Force Fa = 1.25 × Q + A + g
Lekhetlong la ho phomola M = 1.25 × × olx - O × o - g
Mohlala: Moroalo o sebetsang le boholo ba kokoanyana ea conmshell e tsejoa ka tsela e latelang:
Q = 260 KN LMAX = 23 M 1Max = 23M
A = 75 kn e amax = 11 m maria = 11m
O = 450 kno o = 0,75 m o = 0,75m
G = 900 kno = 3 m g = 3m
W = 27 kn r = 6.5 m1) r = 6.5m
Moroalo o matla oa matla a motlakase oa moea ho isa lilemong tse 8
Fa = Q + a + o + g
= 260 + 75 + 4000 + 900 + 900 + 900
= 1685 kn
M = q × × Amax + w × r - o - g × g
= 260 × 23 + 75 × 11 + 27 + 27 + 27 + 27 + 27 × 20 × 4505 × 900 × 300 × 300 × 300 × 300 × 300 × 300 × 300 × 300

2) Ho sa tsotellehe lebotho la moea, nahana ka mojaro o phahameng oa ho sebetsa ka bongata ba 25% ea liteko
Fa = 1.25 × Q + A + g

M = 1.25 × × × ob
= 325 × 23 + 75 × 11 × 4,75 × 900 × 3

3) Moroalo o matla oa ho sebetsa o sa tsotelehe oa matla a moea
Fa = 1685 kn
M = q × × obsaete
= 260 × 23 + 75 × 11 × 450 × 0505 × 900 × 3

Boemo ba Moroallo ba 2 bo sebelisoa e le moroalo o sebetsang oa palo ea lipalo
Ho latela kemiso ea 1, Crate ea Portal (Grab Crocket) e lokela ho tšehetsoa ke mela e meraro ea suller -
Moroalo oa litšupiso oa Statical oa tšehetso ea potoloho ke:

Moroalo oa lipalo oa bolt ke:
Fa = 1750 kno m = 5566.3 knon
Ho latela lintlha tse ka holimo ho lipalo tse kaholimo
Tlhaloso e kaholimo ke mokhoa o qaqileng oa ho balaho rokella ho llaboholo. Ho latela sephetho sa lipalo, o ka khetha tse loketsengho rokella ho llamohlala ho ronaCatalog ea sehlahisoa. Haeba u sa tsebe ho bala, ka kopo ikutloa u lokolohile ho ikopanya le rona ka lengolo-tsoibila. Re tla u sebeletsa ka pelo eohle!
