Question asked by Filo student

Fig. $9.14$ 9.18 A rod of length $1.05\mathrm{m}$ having negligible mass is supported at its ends by two wires of steel (wire A) and aluminium (wire B) of equal lengths as shown in Fig. 9.15. The cross-sectional areas of wires $\mathrm{A}$ and $\mathrm{B}$ are $1.0{\mathrm{mm}}^2$ and $2.0{\mathrm{mm}}^2$, respectively. At what point along the rod should a mass $m$ be suspended in order to produce (a) equal stresses and (b) equal strains in both steel and aluminium wires. $9.19\mathrm{A}$ mild steel wire of length $1.0\mathrm{m}$ and cross-sectional area $0.50\times 10^{-2}{\mathrm{cm}}^2$ is
