A pressure-vessel head is supported by a set of steel cables of length \(2 \mathrm{~m}\) as shown in Fig. 2.75. The time period of axial vibration (in vertical direction) is found to vary from \(5 \mathrm{~s}\) to \(4.0825 \mathrm{~s}\) when an additional mass of \(5000 \mathrm{~kg}\) is added to the pressure-vessel head. Determine the equivalent cross-sectional area of the cables and the mass of the pressure-vessel head.
