A
composite bar of length
is made from a bar of material
1 and length
attached to a bar of material
2 and length
.
(a) We have to show that the effective
coefficient of linear expansion
for this bar is given
by
.
(b) Using steel and brass we have to design
such a composite bar whose length is 52.4 cm
and whose effective coefficient of linear
expansion is
.
The
coefficients of linear expansion for steel and brass are
and
.
