Summary
Loads are often idealised as point forces or distributed intensities for analytical simplicity. More importantly, they are often stipulated for a given problem. This chapter hightlights the need to consider how loads, and their reactions, behave (and form) when geometrical nonlineatrity is evident. Two examples are analysed in detail: the formation of a beam 'ruck' on a rough floor, and the 'snapping-through' of a shallow pin-jointed arch.
