part A

part A

  The temperature coefficient of linear expansion of steel is 12× 10−6 K−1 . When the temperature increases from 5 °C to 25 °C, what is the increase in the length of a straight 25 m length of unclamped railway track? Give your answer in meters.

 

PArt B

A titanium metal rod has been inserted into the tibia of an injured soccer player. The rod, which runs the length of the tibia,is 0.55 m long and is normally at a constant temperature of 37 °C. Suppose that the soccer player develops a severe fever and his core

temperature rises to 40 °C. The linear coefficient for thermal expansion of titanium is 8.6× 10−6 K−1 . By how much will the length

of the titanium rod increase? Express your answer in microns. (10^-6 m=1 micron)
