This subject is an unsolved problem in physics and naval architecture, even though the buoyancy taught by Archimedes' principle (1) can be obtained clearly by the surface integral of hydrostatic pressure.  Then we thought that the reason why the vertical position of the center of pressure could not be determined was that the horizontal force would be zero due to equilibrium in the upright state.\n　As a breakthrough, we dared to assume the left - right asymmetric pressure field by inclining the ship with heel angle θ.  In that state, the force and moment due to hydrostatic pressure were calculated correctly with respect to the tilted coordinate system fixed to the floating body.  By doing so, we succeeded in determining the center of pressure.\n　Then, by setting the heel angle θ to zero, it was proved that the center of hydrostatic pressure is equal to the well-known center of buoyancy, i.e., the centroid of the cross - sectional area under the water surface.\n　Specifically, the above proof is first shown for a rectangular cross - section, and then for an arbitrary shape of floating body by applying Gauss's integral theorem.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1_publisher_20":{"attribute_name":"発行者","attribute_value_mlt":[{"subitem_publisher":"長崎総合科学大学附属図書館運営委員会","subitem_publisher_language":"ja"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1274191X","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"24239976","subitem_source_identifier_type":"EISSN"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagasaki Institute of Applied Science"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"長崎総合科学大学"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-01-06"}],"displaytype":"detail","filename":"pp.135-154 ”Proof that the Center of Buoyancy is Equal to the Center of Pressure by means of the Surface Integral of Hydrostatic Pressure Acting on the Inclined Ship” By Tsutomu HORI(Vol.61 No.2).pdf","filesize":[{"value":"817.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Proof that the Center of Buoyancy is Equal to the Center of Pressure by means of the Surface Integral of Hydrostatic Pressure Acting on the Inclined Ship","url":"https://nias.repo.nii.ac.jp/record/864/files/pp.135-154 ”Proof that the Center of Buoyancy is Equal to the Center of Pressure by means of the Surface Integral of Hydrostatic Pressure Acting on the Inclined Ship” By Tsutomu HORI(Vol.61 No.2).pdf"},"version_id":"d92f3787-6c47-49f7-aa32-047712ef5128"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Center of Buoyancy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hydrostatic Pressure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Inclined Ship","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Surface Integral","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Archimedes' Principle","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Rectangular Section","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Arbitrary Shape","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Gauss’s Integral Theorem","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Proof that the Center of Buoyancy is Equal to the Center of Pressure by means of the Surface Integral of Hydrostatic Pressure Acting on the Inclined Ship","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Proof that the Center of Buoyancy is Equal to the Center of Pressure by means of the Surface Integral of Hydrostatic Pressure Acting on the Inclined Ship","subitem_title_language":"en"}]},"item_type_id":"1","owner":"16","path":["169"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-01-06"},"publish_date":"2022-01-06","publish_status":"0","recid":"864","relation_version_is_last":true,"title":["Proof that the Center of Buoyancy is Equal to the Center of Pressure by means of the Surface Integral of Hydrostatic Pressure Acting on the Inclined Ship"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-02T07:35:47.271829+00:00"}
