Unsymmetrical Bending Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SML-10082
Jlab Export is a leading Unsymmetrical Bending Apparatus Manufacturer,and suppliers in India
Unsymmetrical Bending Apparatus (code EL-SML-10082) is a cantilever rig: an 80 cm angle of 1 x 1 x 1/8 inch section is clamped at one end, loaded vertically at the free end, and its horizontal and vertical tip deflection read on a dial gauge with magnetic base. The clamp turns the section so its principal axes can be inclined to the load. JLab builds this angle-section cantilever rig in Ambala, India.

Why an Inclined Angle Section Bends Sideways
Every cross-section has two principal axes through its centroid, about which the product of inertia is zero; for an equal angle one is the axis of symmetry through the heel. A vertical load acting along a principal axis gives symmetrical bending, and the free end moves only in the load line. Once the clamp tilts the principal axes, the beam bends about non-principal axes: the load is resolved into components along the two principal axes, and each gives a tip deflection of (component) × L³/(3EI) with the second moment about its own axis. As the two principal second moments of an angle differ widely, the free end also moves sideways, towards the direction in which the section is least stiff, and the neutral axis is no longer perpendicular to the load plane.
Taking Readings at Different Clamp Angles
With the section set at one angle, the dial gauge is zeroed against the free end and the load raised in steps, noting the horizontal and vertical movement each time. The resultant deflection is the square root of the sum of their squares, and its direction follows from their ratio. Repeating this at several clamp angles, one with a principal axis vertical, gives values to compare with those calculated from the angle’s principal second moments.
