SAURARA: FA mai mahimmanci shine mafi aminci. Dole ne a yi amfani da shi a hade tare da murfin nauyi mai tsauri. Ya zo daga gwaninta da gwaji. Darajar ma'ana ce dangane da iyakar nauyin aiki.
Misali: Tashar Craan Crane
Hanyar lissafin da aka bayar da shawarar an ba da shawarar kamar haka:
Kafin zabar tallafin Rotary, abin da ya kamata a yi la'akari da shi don mai watsa shiri ya kamata a ƙaddara shi, wanda za'a iya samu a cikin jadawalin 1. Fs = 1.45
Lokacin da matsakaicin nauyin da aka sani an san shi, tsarin lissafin sa shine kamar haka:
1) Matsakaicin aiki mai nauyin iska mai ƙarfi
FAILE FA = Q + A + O + G
Lokaci na Tudewa M = Q × lmex + A × AN R - O × O - G
2) Ba tare da la'akari da ƙarfin iska ba, la'akari da nauyin gwajin 25%
FAIEL FARE FA = 1.25 × Q + A + B + G
Lokacin Twerarning M = 1.25 × q × l× lm + × nix - o × o - s ×
Misali: nauyin aiki da amplitude na tashar jirgin ruwa ana sansu da haka:
Q = 260 kn lmax = 23 m 1max = 23m
A = 75 Kn Amaq = 11 m Amax = 11m
O = 450 kn O = 0.75 m o = 0.75m
G = 900 kn g = 3 m g = 3m
W = 27 kn r = 6.5 m1) r = 6.5m
Matsakaicin nauyin aiki na ƙarfin iska a matakin 8
FA = Q + A + O + G
= 260 + 75 + 900 + 900
= 1685 kn
M = q × lm + a × nox + w × r - o × o - g × g
=260 × 23 + 75 × 11 + 27 ×6.5×450 ×0.75×900 × 3
= 3943 knm
2) Ba tare da la'akari da ƙarfin iska ba, la'akari da iyakar aikin aiki 25% gwajin kaya
FA = 1.25 × Q + A + B + G
= 325 +75 +950 +900
= 1750kn
M = 1.25 × q × l× lm + A × nix - o × o - g
= 325 × 23 + 75 × 11 × 45 × 0.75 × 900 × 3
= 5566.3 knm
3) Matsakaicin aikin aiki ba tare da amfani da ƙarfin iska ba
FA = 1685 kn
M = q × lmax + × nix - o × o - g
= 260 × 23 + 7 + 75 × 11 × 450 × 0.75 × 900 × 3
= 3767.5 knm
Ana amfani da yanayin kaya 2 azaman nauyin aiki na ma'aunin motsi

Matsakaicin Magana mai Bayani na Tallafin Rotary shine:

Accoultar dala na baka shine:
FA = 1750 Kn M = 5566.3 knm
Dangane da tsarin lissafin da ke sama sakamakon, zaɓi na ƙarfin ƙarfin ƙarfin da za a iya ƙuduri don zaɓar tallafin Rotary na 13 * .45.2000.002
