Two bars of different materials and same size
are subjected to the same tensile force. If the
bars have unit elongation in the ratio 2: 5, then
the ratio of modulus of elasticity of the two
materials will be
(a) 2:5
(c) 4 :3
(b) 5:2
(d) 3:4
The composite member is shown in the figure. If the rigid
bar remains horizontal after the loading is applied and
a temperature change of +10°C. Determine the total
stresses on each of the vertical members considering
actual stress due to the loading carried and due to
temperature change. Given on the table below are the
properties of each material used as members.
