Heat of the force that press a gram bilges cold the method that shrink,

Especially beautiful 亞 overcomes the 熱 脹 cold 縮 of force to measure 計 to calculate a method

1.The 溫 that assumes the 亞 of 1000 millimeter 長 overcomes force board is spent rise by 15 degrees 42 degrees, 熱 Peng 脹 measures 則 為 :

× of 10 of × of 7 of 1000 millimeter × (42 - 15) 1.89 millimeter of ＝

2.Board 溫 spends the 亞 gram force that assumes 長 spends 1000 millimeter of 為 to fall by 20 degrees 30 degrees, receive 縮 to measure 為 :

× of 10 of × of 7 of 1000 millimeter × (20 - (, 30) 3.5 millimeter of ＝
