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 7:2 . 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 4.650 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?

A 25.0 ? steel wire and a 50.0 ? copper wire are attached end to end and stretched to a tension of 145 ?. Both wires have a radius of 0.450 ??. and their densities are 7.86 ? 10? ??/?? for the steel and 8.92 ? 10? ??/?? for the copper. (Note that these are mass densities, mass per unit volume, NOT linear mass densities, mass per unit length.) How long does a wave take to travel from one end...

In the figure, a 140 kg uniform log hangs by two steel wires, A and B, both of radius 1.00 mm. Initially, wire A was 2.50 m long and 2.20 mm shorter than wire B. The log is now horizontal. Young's modulus for steel is 2.00 × 1011 N/m2. What are the magnitudes of the forces on it from (a) wire A and (b) wire B? (c) What is the ratio dA/dB?

Two wires made of copper and aluminum have the same length and diameter. The wires are fused together end-to-end to form a single wire. A potential difference is applied to the ends of the wire by a battery so that current flows along the wire. What is the ratio of the electron drift velocity between the two metals, reported as ?

Two 40 ft long wires made of different materials are supported from the ceiling of a testing laboratory. Wire (1) is made of material H and has a diameter of 3/8 in. Wire (2) is made of material K and has a diameter of 3/16 in. When a load of 225 lb is applied to its lower end, wire (1) stretches 0.10 in. When the same 225 lb load is applied to the lower end of wire (2), wire (2)...
