Question
The Stanford linear accelerator contains hundreds of brass disks tightly fitted into a steel tube (see figure). The coefficient of linear expansion of the brass is 2.00 x10-5per C°. The system was assembled by cooling the disks in dry ice (-57°C) to enable them to just slide into the close-fitting tube. If the diameter of a disk is 80.00 mm at 43°C, what is its diameter in the dry ice?
A) 78.400 mm
B) 79.998 mm
C) 80.160 mm
D) 79.840 mm
E) none of these
