The loading sector of 180 degrees is divided into 24 as in the model the No of nodes along the line are 25.The number of degrees per increment comes out to be 7.5.The loads calculated for the half of the sector are shown in the table below. For the next half same loads are applied. The model is fixed from the top and pin load is applied on the lower half section.
