Shape of Three Hinged Arch
The shape of a three hinged arch is determined by the distribution of the load and the geometry of the arch. The shape of the arch is important in determining the strength and stability of the structure. The shape of the three hinged arch is determined by the type of curve that it follows. The three most common curves for arches are circular, parabolic, and hyperbolic.
Parabolic Curve
The parabolic curve is the most common curve for three hinged arches. This curve is formed by the intersection of a plane with a cone. The shape of the arch is determined by the span, the rise, and the load distribution. The parabolic curve is ideal for arches because it distributes the load uniformly and provides maximum strength and stability.
Circular Curve
The circular curve is another common curve for three hinged arches. This curve is formed by the intersection of a plane with a cylinder. The shape of the arch is determined by the span, the rise, and the load distribution. The circular curve is less efficient than the parabolic curve because it concentrates the load at the crown of the arch.
Hyperbolic Curve
The hyperbolic curve is the least common curve for three hinged arches. This curve is formed by the intersection of a plane with a hyperboloid. The shape of the arch is determined by the span, the rise, and the load distribution. The hyperbolic curve is not ideal for arches because it concentrates the load at the abutments and the crown.
Conclusion
In conclusion, the shape of a three hinged arch is determined by the distribution of the load and the geometry of the arch. The three most common curves for arches are circular, parabolic, and hyperbolic. The parabolic curve is the most efficient curve for arches because it distributes the load uniformly and provides maximum strength and stability.
