Unformatted text preview: 9. The steel bed of a suspension bridge is 175 m long at 68 degrees F. The bridge is designed to be safe between the temperature limits of — 25 degrees F to + 105 degrees F. How much will the bridge contract and expand between these thermal limits? The linear coefﬁcient of expansion for steel is 12 x 106/ degree C. L0 = WEM To: 935’: = 26¢ Tm“ ‘1 '0??? = HO.Q0C T .

The next day the temperature rises to + 25 degrees C. How much gasoline will spill from the tank? The volume coefﬁcient of thermal expansion for steel is 3.6 x 105/ degree C. The volume coefﬁcient of themial expansion for gasoline is 9.5 x 104/ degree C.
