Suppose due to a bad break of your femur, you require the insertion of a titanium rod to help the fracture heal. The coefficient of linear expansion for titanium is a-8.60-106 K and the length of the rod when it is in equilibrium with the leg bone and muscle at 37.0°C is 5.10 cm. How much shorter was the rod at room temperature (20.0°C)? um
Older railroad tracks in the U.S. are made of Part A 12-m-long pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16° C, how large should the gaps be if the track is not to buckle when the temperature is as high as 50° C? The coefficient of linear expansion of soft steel is 1.1 × 10-5 °C-1.

A steel rod 30.0 m long, installed when the temperature was 10°C, is in a bridge that heats up to 40oC on a hot summer day. Steel's coefficient of linear expansion is 1.2 × 10-5 K-1. The bridge is built so the rod has an expansion space of 5 cm. Is this enough space? What is the increase in the length of the rod, in mm?
1. Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 17 -L capacity when at 10 °C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95 °C operating temperature, given that the fluid's volume coefficient of expansion is ß= 400 ×10-6/°C? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95 °C. The volume coefficient of expansion of copper is 5.1 x 10-5/°C. Hint: Consider the expansions of both the fluid and the radiator. AV: L
