Curved Member Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SML-10072
Jlab Export is a leading Curved Member Apparatus Manufacturer,and suppliers in India
Curved Member Apparatus (code EL-SML-10072) is a set of steel bar specimens bent into a circle, a semicircle with a straight arm, a quadrant and a quadrant with a straight arm, each fixed to the base at its lower end. A load hung at the free end produces horizontal and vertical deflections that the dial gauge measures. JLab bends and mounts these steel members in Ambala, India.

Deflections by Castigliano’s Theorem
For a thin curved bar, bending energy dominates, so the strain energy is U = ∫ M² ds / (2EI) taken along the arc. Castigliano’s theorem gives the deflection in the direction of the load as δ = ∂U/∂W. The deflection at right angles to the load is found by adding an imaginary force Q in that direction, differentiating with respect to Q and then setting Q to zero. Writing M as a function of the angle around each shape gives a separate pair of predicted deflections for the circle, the semicircle, the quadrant and the arm-extended forms.
What the Four Shapes Show
Testing the four members under the same weights shows how the geometry of the curve, and the extra straight arm, change both deflection components. A vertical load on a curved bar also moves its free end sideways, which a straight horizontal cantilever under the same load would not do, so the horizontal reading is the clearest check on the energy method.
