PHXI09:MECHANICAL PROPERTIES OF SOLIDS

369835 The adjacent graph shows the extension \((\Delta l)\) of a wire length \(1 \mathrm{~m}\) suspended from the top of a roof at one end with a load \(W\) connected to the other end. If the cross-sectional area of the wire is \(10^{-6} \mathrm{~m}^{2}\), calculate the Young's modulus of the material of the wire
