Arches
An arch is an effective way of bridging a gap. An arch converts the downwards force of gravity into horizontal forces which push outwards towards the abutments supporting the arch at either side.
Stone is a good material for building arches as stone performs well under compression and the forces in an arch keep the stones under compression. The most important stone in an arch is the keystone which is the stone at the very center at the top of the arch. The stones to either side of this are called 'voussoirs' and they exert a force on the keystone.
