Two Hinged Arch Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SML-10081
Jlab Export is a leading Two Hinged Arch Apparatus Manufacturer,and suppliers in India
Two Hinged Arch Apparatus (code EL-SML-10081) is a mild steel arch of 100 cm span and 25 cm rise, hinged at both ends, with one end also free to slide along the span. A lever at that end applies a known inward force to measure the horizontal thrust. The arch, lever and stand are made by JLab in Ambala, India.

One Redundant: the Horizontal Thrust
A two-hinged arch has four reaction components and three equations of statics, so it is indeterminate to the first degree. Treating it as a simply supported curved beam with H as the redundant, strain energy gives H = ∫ M₀ y ds / EI ÷ ∫ y² ds / EI, where M₀ is the free bending moment and y the height of the arch axis at each point. In the test, the sliding end is allowed to move under a given load and its horizontal displacement is read on the dial gauge for comparison with the analysis; the lever force needed to push it back is the measured thrust.
Influence Line for Horizontal Thrust
Moving a single load across the marked points and recording H at each position gives the influence line ordinates directly. They can also be found from displacements: if a load at any point moves the released end outward by Δ, and a unit horizontal force at that end moves it by δ, the thrust is H = Δ / δ. Both sets of ordinates can then be compared with the theoretical curve.
Other Arch, Beam Theorem and Frame Apparatus
- Three Hinged Arch Apparatus — determinate arch of the same span and rise, with a crown hinge.
- Verification Clerk Maxwell Reciprocal Theorem — checks the reciprocal theorem by swapping load and dial-gauge points on a beam.
- Portal Frame Apparatus — frame whose roller end feeds a spring balance for horizontal reaction.
