[amp_mcq option1=”Less than 60%” option2=”50%” option3=”More than 50%” option4=”None of these” correct=”option3″]<\/p>\n
The correct answer is: C. More than 50%<\/strong><\/p>\n A self-locking machine is a machine that can lock itself in place without the need for external assistance. This is achieved by using a mechanism that allows the machine to generate its own power, which is then used to lock the machine in place.<\/p>\n The efficiency of a self-locking machine is the percentage of the input energy that is converted into output energy. A machine with an efficiency of 100% would convert all of the input energy into output energy, while a machine with an efficiency of 50% would convert only half of the input energy into output energy.<\/p>\n In order for a self-locking machine to be effective, it must have an efficiency of greater than 50%. This is because the machine must be able to generate enough power to lock itself in place, even when there is a load on the machine.<\/p>\n If the efficiency of the machine is less than 50%, then the machine will not be able to generate enough power to lock itself in place, and it will not be able to function as a self-locking machine.<\/p>\n Option A: Less than 60%<\/p>\n This option is incorrect because a self-locking machine must have an efficiency of greater than 50% in order to be effective.<\/p>\n Option B: 50%<\/p>\n This option is incorrect because a self-locking machine must have an efficiency of greater than 50% in order to be effective.<\/p>\n Option D: None of these<\/p>\n This option is incorrect because there is one option that is correct.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Less than 60%” option2=”50%” option3=”More than 50%” option4=”None of these” correct=”option3″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[645],"tags":[],"class_list":["post-6784","post","type-post","status-publish","format-standard","hentry","category-applied-mechanics-and-graphic-statics","no-featured-image-padding"],"yoast_head":"\n
