Frame Deflections and Reactions Manufacturer,Supplier and Exporter in India
Product Code : EL-NGSP-11388
A precision indicator measures any horizontal deflection (sway) at the junction of the beam and the upright.
Students fit one of a choice of two frames between two supports and apply vertical loads to the beam member.
Load cells in the supports measure the bending moment and horizontal reaction at the base of the uprights due to the load.
Each support includes pointers that work with the scale on the platform for accurate positioning.
This allows the students to understand the two causes of frame sway other than direct loads.
Students apply loads to the portal frame.
They use textbook equations and analysis to predict the reaction forces and fixing moments due to the load and whether or not the frame will sway and its magnitude.
They compare predictions to measured and observed results.
One of the frames has a uniform second moment of area for both the uprights and the beam, the other has one upright with a second moment of area of approximately half that of the other upright and the beam. Both frame beams can be loaded anywhere along their length.
This product includes a Vernier caliper for accurate measurement of the frame cross-section.
The deflection indicator has its own display but it can connect (with the load cells) to the USB interface hub of the Structures platform for computer display and data acquisition.
