369862 A thick rope of density \(\rho\) and length \(L\) is hung from a rigid support. The Young's modulus of the material of rope is \(Y\). The increase in length of the rope due to its own weight is

1 \((1/4)\rho g\,{L^2}{\rm{/}}Y\)
2 \((1/2)\rho g\;{L^2}{\rm{/}}Y\)
3 \(\rho g\;{L^2}{\rm{/}}Y\)
4 \(\rho g\;L{\rm{/}}Y\)

369863 \(\quad A\) and \(B\) are two wires and the radius of a \(A\) is thrice that of \(B\). They carry the same load then the stress on \(\mathrm{B}\) is

1 Equal to that on \(A\)
2 Four times that on \(A\)
3 Two time that on \(A\)
4 Nine times that on \(A\)
PHXI09:MECHANICAL PROPERTIES OF SOLIDS

369864 When a rod is heated but prevented from expanding, the stress developed is independent of

1 material of the rod
2 rise in the temperature
3 length of the rod
4 None of these
