Two wires A and B of the same material have lengths in the ratio $1 : 2$ and diameters in the ratio $2 : 1$. TA uniform pressure $P$ is applied isotropically to a solid sphere of bulk modulus $K$. The fractional change iThe Poisson's ratio of a material is defined asThe theoretical range of Poisson's ratio for an isotropic material isThe elastic potential energy stored per unit volume in a stretched wire (within the elastic limit) isA steel rod is clamped rigidly at both ends and then heated through a temperature rise $\Delta T$. If $\alpha$A wire of length $L$, area $A$ and Young's modulus $Y$ is stretched by hanging a mass $m$ from its free end.
