We use the gyroscopic balance condition of Moffatt and Shimomura and analyze the slip velocity of the bodies at the point of contact as a function of θ, the angle between the axis of symmetry and the vertical axis, and find the existence of the critical angle u c . When the bodies are spun with an initial angle θ initial > θc, θ will increase to p, implying that the body will spin at the thin end. Alternatively, if θ initial < θc, then θ will decrease. For some oval curves, θ will reduce to 0 and the corresponding bodies will spin at the fat end. For other oval curves, a fixed point atθf is predicted, where 0 < θf < θc. Then the bodies will spin not at the fat end, but at a new stable point with θf. The empirical fact that eggs more often spin at the fat than at the thin end is explained.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ササキ, ケン"}]}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Association of Physics Teachers"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1119/1.1634966","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00521097","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00029505","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Physics, Faculty of Engineering, Yokohama National University = 横浜国立大学大学院工学研究院  知的構造の創生部門  物理科学と知の創造分野"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sasaki, Ken"}],"nameIdentifiers":[{"nameIdentifier":"17622","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-09-16"}],"displaytype":"detail","filename":"ks-eggs.pdf","filesize":[{"value":"113.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ks-eggs.pdf","url":"https://ynu.repo.nii.ac.jp/record/3962/files/ks-eggs.pdf"},"version_id":"a9b4b284-af60-4937-b8be-c002b7b56e72"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Spinning eggs : which end will rise?","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Spinning eggs : which end will rise?"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-28"},"publish_date":"2011-03-28","publish_status":"0","recid":"3962","relation_version_is_last":true,"title":["Spinning eggs : which end will rise?"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T21:35:44.927935+00:00"}
