So far, the discussion has been with reference to loads which are acting vertically upwards or downwards. However, in practice, there are many situations where the beams are subjected to inclined loads and to transverse loads. In such cases, ordinary supports cannot create an equilibrium condition because horizontal supports cannot be balanced. Hence, one of the supports is provided as a hinged support and the other as a roller support. Hinged support takes care of the horizontal unbalanced force and the roller support the vertical forces.

All inclined forces are resolved into two mutually perpendicular components one perpendicular to the axis of the beam and the other parallel to the axis.

Perpendicular ...
