A 1.0-m rigid horizontal support is hung by two cables as shown. One cable is brass and The other cable is high-density polyethylene plastic. At room temperature (21°C), the cables measure 3.50 m vertically. When the temperature drops to 15°C, find the following:
(a) The change in length in each cable
(b) The change in elevation of points A, B, and C
