Question
Three prismatic bars, two of material A and
one of material B, transmit a tensile load P (see figure).
The two outer bars (material A) are identical. The
cross-sectional area of the middle bar (material B)
is 50% larger than the cross-sectional area of one
of the outer bars. Also, the modulus of elasticity of
material A is twice that of material B.
(a) What fraction of the load P is transmitted by
the middle bar?
(b) What is the ratio of the stress in the middle bar
to the stress in the outer bars?
(c) What is the ratio of the strain in the middle bar
to the strain in the outer bars?
