The remaining contacts all are bonded<\/p>\n<p><strong>Results- I see that the back wheel of the cart is lifting off from the ground before the front wheel impacts. and after impact entire cart is flying. What could be the reason for this how can I control the cart to remains stay with the ground?<\/strong><\/p>\n","protected":false},"template":"","class_list":["post-160054","topic","type-topic","status-closed","hentry","topic-tag-transient-structural"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["2605"],"_bbp_likes_count":["0"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["160054"],"_bbp_forum_id":["27791"],"_bbp_engagement":["199","240","156272","180472"],"_bbp_voice_count":["4"],"_bbp_reply_count":["18"],"_bbp_last_reply_id":["184328"],"_bbp_last_active_id":["184328"],"_bbp_last_active_time":["2021-07-14 11:38:19"]},"test":"happykiran"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/160054","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\/160054\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=160054"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
