The Pendulum set consists of the following elements: Escapement Wheel, Needle Indicator, Pendulum with an Anchor, and Pendulum Bob. In the heart of this set is a rubber band that both powers the mechanism and compensates for the kinetic energy loss. The force of gravity together with the tension force of the rubber band affects the amplitude oscillation which illustrates the working principle of any pendulum mechanism. The oscillation’s frequency is controlled by means of the weight of the Pendulum Bob and the resistance in the rubber band, while the mechanism is started with the help of a wind-up wheel that is connected to a gear unit.\u003cbr\u003e\u003cbr\u003eSpecifications:\u003cbr\u003e\u003cbr\u003eDimensions: 8.1 × 7.4 × 2.5 in \u003cbr\u003eAssembled size: 4.5\"x3.3\"x6.6\" \u003cbr\u003eEstimated time of assembly: 1-3 hours\u003cbr\u003eDifficulty level: Easy\u003cbr\u003eNumber of parts: 92\u003cbr\u003eTools and materials: Made of high quality plywood; assembly requires no glue or cutting\u003cbr\u003eRecommended Age: 14+\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Factory New\u003cbr\u003e\u003cstrong\u003eOperational Status:\u003c\/strong\u003e \u003ca href=\"#\" title=\"This item is brand new from the factory.\"\u003eFunctional\u003c\/a\u003e\u003cbr\u003e\u003cstrong\u003eOriginal Box:\u003c\/strong\u003e Yes\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eManufacturer:\u003c\/strong\u003e UGears\u003cbr\u003e\u003cstrong\u003eModel Number:\u003c\/strong\u003e 12116\u003cbr\u003e\u003cstrong\u003eMSRP:\u003c\/strong\u003e $25.99\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCategory 1:\u003c\/strong\u003e Model Kits\u003cbr\u003e\u003cstrong\u003eCategory 2:\u003c\/strong\u003e Other Scales\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eThe Trainz SKU for this item is P12606767. \u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size: 6px !important; color: #d3d3d3 !important; line-height: 8px !important;\"\u003eTrainz Product Id: 12606767\u003c\/span\u003e","brand":"UGears","offers":[{"title":"Default Title","offer_id":39822899544186,"sku":"P12606767","price":22.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1260\/4747\/products\/P12606767-922A60D4.jpg?v=1678333339","url":"https:\/\/www.trainz.com\/products\/ugears-12116-stem-lab-pendulum-3d-wooden-model-kit","provider":"Trainz","version":"1.0","type":"link"}
