If the boom touches or rests on any structure, the boom loading changes from ______ to bending.

Explanation:
When the boom is free and supported mainly at the base (often with stay wires), the load path along the boom is mostly axial, so the member carries compression. If the boom touches or rests on a structure, that contact introduces an off-axis reaction, creating a moment about the boom and producing bending along its length. So the loading changes from compression to bending when contact occurs.
