On the method estimating the sag of the loaded skyline cable by using a period of oscillation (1)横揺れ週期に依る負荷架空索の中央垂下量の推定法に就て(第1報)鳥山, 清美34954By using a period of oscillation of a skyline cable on which one concentrated load hangs, a value of its middle sag can be estimated. Formula (14) is practical formula under this case. Now, C_0 and β are coefficients whose value are given in Fig.1 and Fig.2 respectively. β in (14), however, contains fo to be pursued, therefore we have to put forward the oparation as follows. First of all the first approximate value (f_1) is calculated by formula (15), then get a value of β_1 corespohding v_1=e/f_1 Through Fig.2. the second approximate value (f_2) will be soon calculated thus f_2=β_1f_1. When we repeat this oparation several times in the same way, f_1, f_2, f_3……will astrigent to a true value (f_0). Generally, the third approximate value (f_3) may satisfy our demand enough.Article信州大学農学部学術報告 5: 68-75(1956)departmental bulletin paper信州大学農学部1956-04-20application/pdf信州大学農学部学術報告568750559-8605AN00121341https://soar-ir.repo.nii.ac.jp/record/11150/files/Bulletin_Agri-05-08.pdfjpn
