App\Entity\MediaTranslation {#1381 -id: 6845 -title: "Gears sketch" -description: """ <p>A gear train is formed when at least two toothed wheels are interconnected. Only a toothed wheel is driving. The others are just trained (or "led"). A smaller driven wheel than the driver wheel will rotate faster and conversely a larger driven wheel will rotate more slowly.</p>\r\n \r\n <p>It is on this principle that the mechanisms of changes of speed are based. The gear ratio is also called the "transmission ratio". The gear system + chain transmission of the bike is a very good illustration of the transmission of a rotational movement between two wheels. The rotation speed of the rear gears depends on the transmission ratio between the platform (front wheel) and the pinion (rear wheel).</p>\r\n \r\n <p>To find the transmission ratio of a gear train is to compare the numbers of teeth and thus the radii.</p>\r\n \r\n <p><strong>Draw</strong> a circle in the screen to create a wheel. The size of the wheels is constrained to illustrate simple ratios: 10, 15, 20, 30, 40, 50, 60 teeth.</p>\r\n \r\n <p>The driving wheel is grayed out. All driving wheels rotate at the same speed.</p>\r\n \r\n <p><strong>Surround</strong> two wheels to create a transmission chain.</p>\r\n \r\n <p><strong>Click</strong> on a wheel to select or drag it.</p>\r\n \r\n <p><strong>Strike </strong>through an item to remove it.</p>\r\n \r\n <p>Credit: Frank Leenaars & eduMedia</p> """ -legends: "Teeth" -goals: """ <ul>\r\n \t<li>To make a gear train and identify the drive wheel and the driven wheel(s).</li>\r\n \t<li>To illustrate how to convey a movement through a chain.</li>\r\n \t<li>To calculate a transmission ratio.</li>\r\n \t<li>To explain how the bike works and the ability to change gears.</li>\r\n </ul> """ -more: null -scenario: null -features: "<p>Draw a circle on the stage to create a wheel.
