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 ?1 to the radius of the second wire ?2 is 5:4. 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 3.350 mm while the two wires stay connected together....
