10 सेमी लम्बाई के एक स्टील के तार के सिरों पर जब ताप में `100^(@)C` की वृद्धि की जाती है, तब इसकी लम्बाई स्थिर रखने के लिये सिरों पर लगाया गया दाब है :
(स्टील का यंग-प्रत्यास्थता गुणांक `2xx10^(11)" न्यूटन मी"^(-2)` और रैखिक प्रसार गुणांक `1.1xx10^(-5)K^(-1)` हैं)
A. `2.2xx10^(8)" Pa"`
B. `2.2xx10^(9)" Pa"`
C. `2.2xx10^(7)" Pa"`
D. `2.2xx10^(6)" Pa"`.

Best answer
विकृति `=(DeltaL)/(L)=alpha DeltaT`
अब दाब = उष्मीय प्रतिबल `=Yxxalphaxx" ताप में वृद्धि"`
`=2xx10^(11)xx1.1xx10^(-5)xx100`
`=2.2xx10^(8)" Pa".`
