Half-disc

A 'half-disc' refers to a shape or object that is precisely half of a complete disc, often characterized by a flat, straight edge (the diameter of the original disc) and a curved, semi-circular boundary. It's a geometric form, often used in design, architecture, and engineering. The 'half-disc' retains all of the properties of the original disc regarding its circular nature on the curved boundary but also possesses an explicit sense of linear definition. The flat edge serves to create a distinct boundary that provides a focal point in its application. It is a fundamental shape in geometry, serving as a building block in complex designs and structural configurations. The object or shape may vary in size, and the material is dependent on its usage.

Half-disc meaning with examples

• The architect utilized a series of 'half-discs' as decorative elements on the building's facade, creating a visually dynamic and striking effect. The repeated, semi-circular shapes provided a gentle rhythm. The flat edges of the shapes ensured a pleasing balance. The curved surface refracted light across the entire surface.
• In the children's craft project, colorful 'half-discs' of felt were used to create stylized suns and moons. The kids could easily cut the shapes out. The straight edges of the felt were good for gluing. The curved side was good for artistic shapes.
• The engineer chose a 'half-disc' of metal to serve as a pivotal support for a bridge component. The shape's robust design provided the structural support, ensuring stability. The flat edge was ideal for attachment. The curved side was useful for stress distribution.
• The designer used 'half-discs' of mirrored glass in the room's decor. The reflective surface added visual interest, while the shape softened the harsh lines. The flat edges provided a stable mounting. The shape reflected a pleasing curved arc to light.
