You are analysing the design of a radio communications installation under wind loading. The
towers are braced using a cable stay system tied back to ground anchors. As part of the analysis,
you need to assess the resultant force on a typical ground anchor. Under your design wind
loading, the magnitude of forces on the anchor are l|F1ll = 100 kN, I|F2|| = 75 kN, ||F3|| = 125 kN,
and ||F4l|| = 200 kN.
a) (LO1, LO4) Sketch the resultant force FR clearly defining its position relative to the
anchor loads and define its angle relative to the positive x-axis as 0.
