Question 50
CENAT2 marksNeeds review
Consider two linearly elastic rods
and
, each of length
, as shown in the figure. The rods are co-linear, and confined between two fixed supports at
and
. Both the rods are initially stress free. The coefficient of linear thermal expansion is
for both the rods. The temperature of the rod
is raised by
, whereas the temperature of rod
remains unchanged. An external horizontal force
is now applied at the node
. It is given that
,
,
,
. The axial rigidities of the rods
and
are
and
, respectively. 
To make the axial force in rod
equal to zero, the value of the external force
(in N) is ________. (round off to the nearest integer)Log in to check the answer
