Question

A linear accelerator has a hundred brass discs tightly fitted into a steel tube. Each disc is 10.02 cm in diameter at 40°C. Discs are cooled in dry ice to -60°C for assembly. With brass $α = 2 \times 1 0^{- 5}^{\circ} C^{- 1}$ , each cold diameter is:

Options:

Answer:

D

Solution:

$d^{'} = 10.02 [1 + (2 \times 1 0^{- 5}) (- 100)]$ .

$d^{'} = 9.99996 cm, approximately 10.00 cm .$
