The load on the tip was measured by a pressure transducer on top of the tip mount and the measured signal was sent via cable to the controlling computer. <\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"X Axis of Single Tip Scratching Tester\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/sgsKkIkHuh4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Y Axis of Single Tip Scratching Tester\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/lAorxvExKCU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Z Axis\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/mxCIDQtIZBw?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Location: George Washington University Test Rig: Single Tip Scratching Tribometer I fixed an &#8220;ancient time&#8221; tribometer by reprogramming the control system to control the movement<\/p>\n","protected":false},"author":1,"featured_media":120,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[6],"tags":[],"_links":{"self":[{"href":"https:\/\/samtari.com\/index.php?rest_route=\/wp\/v2\/posts\/118"}],"collection":[{"href":"https:\/\/samtari.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/samtari.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/samtari.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/samtari.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=118"}],"version-history":[{"count":2,"href":"https:\/\/samtari.com\/index.php?rest_route=\/wp\/v2\/posts\/118\/revisions"}],"predecessor-version":[{"id":121,"href":"https:\/\/samtari.com\/index.php?rest_route=\/wp\/v2\/posts\/118\/revisions\/121"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/samtari.com\/index.php?rest_route=\/wp\/v2\/media\/120"}],"wp:attachment":[{"href":"https:\/\/samtari.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=118"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/samtari.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=118"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/samtari.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=118"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
