কোন এক পার্কের একটি দোলনায় ঝুলতে লোহার তার ব্যবহার করা হয়েছে। কয়েকজন ছেলে-মেয়ে দোলনায় যখন দোল খাচ্ছিল তখন এক বাচ্চার অভিভাবক লক্ষ্য করেন যে, ফুলন তার 1 m থেকে বৃদ্ধি পেয়ে 1.01 m হয়েছে এবং তারটির ব্যাস হ্রাস পেয়েছে। পয়সনের অনুপাত 0.2 হলে দোলনার তারের ব্যাস কতখানি হ্রাস পায় ? (The iron wires have been used in a park to swing.
