A two hinge arch is a structural element that consists of two curved hinges connected by a rigid link. These hinges allow the arch to rotate around a single point, but they restrict the movement of the point of application of a force.
A hinge arch can be considered an indeterminate structure, meaning that its shape is not uniquely determined by its internal forces. This is because the distribution of shear forces within the arch is not unique.
Examples:
Curved bridges: The curved shapes of bridge arches are a classic example of a two hinge arch.
Structural components: In architecture, hinge arches are used in roofs and arches to create curved openings.
Wind turbines: Wind turbines often utilize hinge arches to support the blades and ensure smooth rotation in different wind conditions.
Key points about hinge arches:
They have two hinges connected by a rigid link.
They allow rotation around a single point, but restrict the motion of the point of application of a force.
They are considered an indeterminate structure.
Their shape is not uniquely determined by their internal forces
