A heavy machine tool is transported by a helicopter. The crate containing the machine tool weighs \(12,000 \mathrm{~N}\) and is supported by a steel cable, of length \(5 \mathrm{~m}\) and diameter \(d \mathrm{~m}\), as shown

CARSON Steel cable - length 5m, diameter d m mg - 12,000

in Fig. 2.61. If the natural time period of the crate is found to be \(0.1 \mathrm{~s}\), find the diameter of the steel cable.
