9.7 Aroof membrane (œ = 0.000 120 in/in-°F) will be installed on a flat roof. Once installed, the membrane will be allowed to expand and contract freely. On a hot summer day, the temperature of the roof membrane can rise to 140°F. In the winter, the temperature of the roof membrane can fall to 0°F. Due to the configuration of the roof expansion joint, ex- pansion is limited to 4.5 in and contraction is limited to 3.0 in. (a) Determine the maximum length the membrane can be if it is installed at a tempera- ture of 35°F. (b) Determine the maximum length the membrane can be if it is installed at a tempera- ture of 95°F.
