If the storage tank is to be installed using saddle supports $($as shown in Figure $2)$ at Port Botany where extreme wind loads may arise $($assuming the length of the cylindrical portion of the tank is $14$ meters for the calculation of the resultant wind force acting on the tank$),$ determine the diameter of the bolt used at the fixed saddle support with a factor of safety of $1\mathrm{.}5.$ Assume the allowable shear stress of the bolt material is $340$ MPa and only two identical bolts are used for the fixed saddle support. The location of the two bolts is expected to be discussed in the report. And also assume the wind loads are uniformly distributed on the surface of the tank.

note: the wind speed has been found to be $87\mathrm{.}1$ km$/$h
