369785 Two wires are made of the same material and have the same volume. However wire 1 has cross-sectional area \(A\) and wire 2 has cross-sectional area \(9\;A\). If the length of wire 1 increases by \(\Delta x\) on applying force \(F\), how much force is needed to stretch wire 2 by the same amount?

1 \(16\,F\)
2 \(25\,F\)
3 \(81\,F\)
4 \(64\,F\)

369786 The ratio of the length of two wires \({a}\) and \({b}\) of same materials is \({1: 3}\) and the ratio of their diameters is \({3: 1}\). They are stretched by the same force then the ratio of increase in lengths will be

1 \({1: 9}\)
2 \({27: 1}\)
3 \({1: 27}\)
4 \({9: 1}\)

369787 Two wires of different materials have same length \(\mathrm{L}\) and same diameter \(\mathrm{d}\). The second wire is connected at the end of the first wire and forms one single wire of double the length. This wire is subjected to streching force \(\mathrm{F}\) to produce the elongation \(l\). The two wires have

1 Different stress but same strain
2 Different stress and different strain
3 Same stress and different strain
4 Same stress and same strain
