गोल क्यों होते है ज्यादार गटर के ढक्कन?

दोस्तों आपने भी देखा होगा की गटर के ढक्कन अधिकतर हमे गोल ही देखने को मिलते हैं , जानते हैं क्यों? दरअसल इनका आकार गोल होने के पीछे रचनात्मिक कारण हैं , पहला तो यह की एक गोलाकार ढक्कन आसानी से फिट हो जाती है जबकि अगर यह ढक्कन स्क्वायर या रेक्टेंगल होता तो इसे उसी तरीके से फिट करना पड़ता जैसे इसे बनाया गया था ।

और दूसरा यह की एक स्क्वायर मैनहोल कवर तो गटर में गिर भी सकता है लेकिन एक राउंड मैनहोल का ढक्कन गड्ढे से बड़ा व्यास होने के कारण उसमे गिर नहीं सकती । यह ढक्कन सुरक्षित होने के साथ साथ आसानी से खुलता और बंद होता है। इसे इस्तेमाल करना और कही लेकर जाना भी आसान होता है। इसलिए विश्व में सभी जगह गटर का ढक्कन ज्यादातर गोल ही होता है ।
