Two steel wires are connected together, end to end, and attached to a wall. The two wires have the same length and elastic modulus, but the ratio of the radius of the first wire r1 to the radius of the second wire r2 is 5:2 . As the wires are initially the same length, the midpoint of the combination coincides with the connection point. An applied force then stretches the combination by 3.250 mm while the two wires stay connected together. After the wires are stretched, what is δ , the magnitude of the distance from the midpoint to the connection point?

Two steel wires are connected together, end to end, and attached
to a wall as shown below. The two wires have the same length and
elastic modulus, but the ratio of the radius of the first wire to
the radius of the second wire is 7 : 3. As the wires are initially
the same length, the midpoint of the combination coincides with the
connection point. An applied force then stretches the combination
by 0.550 mm while the two wires...

A compound string is made by fusing together two wires of
different lengths, but of the same radius. Their densities are ρ 1
and ρ 2, where ρ 1 < ρ 2. The string is plucked at the end of
the ρ 1 wire. At the interface, part of the pulse is reflected,
while the other part is transmitted. The transmitted and reflected
pulses reach their respective ends at the same time.
Draw snapshots of what the string looks like...
