I&#8217;m not sure what the issue is. my vibratory movement comes from a displacement at one end. any advice or ideas would be greatly appreciated&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-370896","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["84"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["199","138935"],"_bbp_topic_id":["370896"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","138935"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["371633"],"_bbp_last_active_id":["371633"],"_bbp_last_active_time":["2024-07-12 10:29:23"]},"test":"2956092istudent-gla-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/370896","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/370896\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=370896"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
