Two solid rods have the same length and are made of the same material with circular cross sections. Rod 1 has a radius ?1 and Rod 2 has a radius ?2=?1/2 If a compressive force ?F is applied to both rods, their lengths are reduced by Δ?1 and Δ?2, respectively. The ratio Δ?1 / Δ?2 is equal to The choices are .25, 2., 1., 0.5, 4.

Two square wires are composed differently, see the figure of their cross-sections. Wire 1 is a square wire of material A but with a circular center of material C. The diameter of the circular inside is equal to the length of side of the square. The second square wire has the same cross-sectional area as the first but is entirely comprised of material A. Both wires are the same length and setup to have the same temperature difference maintained between...

A one meter section of circular cross-section wire has a resistance of 382 Ohms. If you stretched the wire (while maintaining a circular cross-section), how long would the wire have to be to have a resistance that is 48.8 times as large? Don't round. The answer should be 6.99 but I need steps to understand the answer.
