स्पष्टीकरण

माना कि εL और εh अनुदैर्ध्य विकृति और परिधीय विकृति है और μ प्वासों अनुपात और E प्रत्यास्थता मापांक है।

हम जानते हैं कि,

अनुदैर्ध्य विकृति:

परिधिक/हूप विकृति:

अब,

हूप विकृति = परिधि या परिधिक मूल परिधि विकृति में परिवर्तन।

 ( δd व्यास में परिवर्तन)

और भी, अनुदैर्ध्य विकृति  

सिलेंडर की आयतनिक विकृति के लिए हम जानते हैं कि = ϵl + 2ϵh
