Gears are a system of interlocking wheels that can create immense mechanical advantages. The amount of mechanical advantage, however, will depend on the gear ratio; that is, on the relation in size between the gears.<\/p>\n<p>Let\u2019s start with something straightforward first.<\/p>\n<p>Problems like these are simple when you know the shortcut.<\/p>\n<p>Now, let\u2019s see a more complicated version of the same thing.<\/p>\n<p>There are two questions regarding this picture, so let\u2019s take them one at a time, first mechanical advantage.<\/p>\n<p>Now, let\u2019s examine the gear ratio and how that impacts the amount of turning these gears do.<\/p>\n<p>Now for a couple fun ones to try by yourself\u2026<\/p>\n<p>Last one\u2026<\/p>\n<p>The answer here is C because we know the ratio is 1:2 which means the larger gear makes half as many turns as the smaller one. Half of 12 turns is 6.<\/p>\n<p>Thanks for watching this video tutorial.<\/p>\n<\/div>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":{"0":"post-19249","1":"page","2":"type-page","3":"status-publish","5":"page_category-simple-machines","6":"page_type-video","7":"page_domain-science"},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/pages\/19249","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/comments?post=19249"}],"version-history":[{"count":5,"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/pages\/19249\/revisions"}],"predecessor-version":[{"id":266257,"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/pages\/19249\/revisions\/266257"}],"wp:attachment":[{"href":"https:\/\/www.mometrix.com\/academy\/wp-json\/wp\/v2\/media?parent=19249"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
