The wire pulls back in proportion to the angle, giving rotational simple harmonic motion. A disc with I = 2 × 10⁻³ kg·m² on a 0.02 N·m\/rad wire swings with a 2.0 s period. Pixel-art kiss-cut sticker in 2, 3, 4 and 6 inches; equation, symbols and sources in the physics panel below.\u003c\/p\u003e","brand":"Printify","offers":[{"title":"2\" × 2\" \/ White","offer_id":50658857255015,"sku":"24921642728375588356","price":4.99,"currency_code":"USD","in_stock":true},{"title":"3\" × 3\" \/ White","offer_id":50658857287783,"sku":"23444580357187371882","price":6.99,"currency_code":"USD","in_stock":true},{"title":"4\" × 4\" \/ White","offer_id":50658857320551,"sku":"25116912481898429304","price":8.99,"currency_code":"USD","in_stock":true},{"title":"6\" × 6\" \/ White","offer_id":50658857353319,"sku":"53254759951032261815","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/8746\/9159\/files\/01_clean_cf281457-4a6a-44ba-bb0b-ba8dcae1f2d3.jpg?v=1792806218","url":"https:\/\/pixelatedphysics.com\/products\/twistel-torsion-pendulum-pixel-sticker","provider":"Pixelated Physics","version":"1.0","type":"link"}
