Question

a
metal is heated, its atoms vibrate more
when
about their position in the lattice (a netuons of crossed burs)
This Causes them to take up more Space, so the solid metal
expands from its original shape.
calculate the heat needed to expand a ring made of copper
internal diameter of Somm to fit over a Shaft of
with an
diameter So.05mm. The shaft is measured at a temp 182

Expert Solution

Step 1 To determine,

Heat needed to expand a ring made of copper.

Given,

$Initial internal diameter (D_{i}) = 50 mm = 50 \times 10^{- 3} m Final internal diameter (D_{f}) = 50.05 mm = 50.05 \times 10^{- 3} m Initial temperature (T_{i}) = 18^{o} C coefficient of linear expansion at T_{i} = 18^{o} C$
