A 0.4974 mile long concrete bridge has thermal expansion coefficient of 0.00158 m/K. The summer heat can get up to 48 degrees C, and the winter down to 4 degrees C. What is the overall change in length over the course of a year, in feet?
Answer: is 182.58 ft
Homework Answers
Length given is 0.4974 mile or 2626.272ft
We know that change in length per unit length is
(thermal expansion coefficient)*(change in temperature)
0.00158(48-4)
=0.06952
So change in length will be
length*(0.06952)
2626.272*(0.06952)
=182.58ft

2-157 A long electrical resistance wire of radius r.-0.25 cm has a thermal conductivity kwire-15 W/m-K. Heat is generated uniformly in the wire as a result of resistance heating at a constant rate of 0.5 W/cm3. The wire is covered with polyethylene insulation with a thickness of 0.25 cm and thermal conductivity of ks 0.4 W/m K. The outer surface of the insulation is subjected to free convection in air at 20°C and a convection heat transfer coefficient of 2...
