Two circular rods, one steel and the other copper, are both
0.755 mm long and 1.50 cm in diameter. Each is subjected to a force
with magnitude 4250 N that compresses the rod. Use copper =
1.1*1011 and steel = 2.0 *
1011.
What is the difference in the length of the two rods when
compressed?
Express your answer in meters to two significant figures.
Answer is NOT 6.05 x 10-5

Two steel rods each of cross sectional area 500mm2,
and an aluminium alloy rod, of cross sectional area 600
mm2 are cut to a length of 3m and attached to rigid end
plates to form a composite member.
If a tensile force of 100kN is applied to the member and at the
same tie the temperature of the system is lowered by 20℃, determine
the force developed in each of the rods and the extension of the
member.

An aluminum rod with a square cross section is 2.0 m long and
6.6 mm on edge. (a) What is the resistance between its ends? (b)
What must be the diameter of a cylindrical copper rod of length 2.0
m if its resistance is to be the same as that of the aluminum rod?
The resistivity of aluminum is 2.75 × 10-8 Ω·m and the resistivity
of copper is 1.69 × 10-8 Ω·m.

Two metal rods, one silver and the other gold, are attached to
each other. The free end of the silver rod is connected to a steam
chamber, with a temperature of 1000C, and the free end of gold rod
to an ice water bath, with a temperature of 00C. The rods are 5.0
cm long and have a square cross-section, 2.0 cm on a side. How much
heat flows through the two rods in 60 s? The thermal conductivity

compression?
2. What is the longitudinal strain in steel rod?
3. What is the modulus of elasticity of the material of the
rod?
4. What is the value of...

Two metal rods of equal length-one aluminum, the other stainless
steel-are connected in parallel with a temperature of 10.0 ∘C at
one end and 122 ∘C at the other end. Both rods have a circular
cross section with a diameter of 7.00 cm Part A Determine the
length the rods must have if the combined rate of heat flow through
them is to be 17.5 J per second. Express your answer using two
significant figures.
