It features a double-spring oscillator configuration with two coiled springs extending in opposite directions from a central yellow mounting block. A built-in horizontal beam functions as a scale marked in centimeters for measuring displacement, amplitude, and equilibrium points. The setup is supported by a stable white rectangular base and a vertical metal rod. Overall dimensions: 45 cm length, 43 cm height.\u003c\/p\u003e","brand":"World Products","offers":[{"title":"Double Spring","offer_id":50414291288303,"sku":"dcd-30003967932","price":4.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0807\/5486\/8463\/files\/2bdcf1ae-629d-41ee-b608-a195751cce9a.jpg?v=1786269934","url":"https:\/\/sendfromchina.ai\/products\/wp-dcd-10001398197","provider":"World Products","version":"1.0","type":"link"}
