Deflection of Beams and Cantilevers
Deflection of Beams and Cantilevers (Product Code: SLE/EG/17) is a flexible beam experiment: loads can be placed at any position along the beam and the resulting deflection measured at any point, with the beam on its supports or fitted to a single support as a cantilever. Built by Jain Scientific Equipments Pvt Ltd (ScienceLab) in Ambala, it comes with beam specimens in different metals and cross-sections for strength of materials classes in engineering colleges and technical institutes.
Key Details
| Parameter | Detail |
|---|---|
| Type | Beam and cantilever deflection experiment |
| Loading | Loads applied at any position along the beam |
| Deflection measurement | Deflection indicator with its own display, usable at any point along the beam |
| Configurations | Beam on supports, or fitted to one support only to form a cantilever |
| Specimens | Set of beam specimens of different metals and cross-sections, for comparing elastic properties and ‘I’ value |
| Span | Effective length of the beam can be varied |
| Positioning | Pointers on each support work with the scale on the platform |
| Data connection | Deflection indicator can connect to the USB interface hub of the Structures Platform for computer display and data acquisition |
Typical Use
A standard session starts with one metal beam at a fixed span: students add load in steps, record deflection and compare it with the value predicted by the textbook beam formula. They then reset the span with the support pointers and platform scale and see how quickly deflection grows as the beam gets longer, before moving the indicator to other points to map the deflected shape.
Switching specimens separates the two ingredients of beam stiffness — the metal’s elastic modulus and the section’s second moment of area (‘I’ value) — so students see why a deeper section or a stiffer metal deflects less. Removing one support turns the beam into a cantilever for tip-load tests. As the indicator works on its own display, the practical runs well as lab equipment for college groups even before the computer link is set up.

Frequently Asked Questions
Can the apparatus be used as a cantilever?
Yes. Fit the beam to one support only and it becomes a cantilever.
Which beam specimens are included?
A set of beam specimens in different metals and cross-sections. For the specific metals and sizes, please contact us.
Does the deflection indicator need a computer?
No, it has its own display. Connecting it to the USB interface hub of the Structures Platform is optional for on-screen display and data logging.
Can the span be changed?
Yes. The effective length can be varied, and pointers on each support work with the platform scale for accurate positioning.
Can students estimate the elastic modulus of each metal?
Yes. Combining the measured deflection with the beam equation and the section’s ‘I’ value lets students compare the elastic properties of the different metals.
What warranty and lead time apply?
Both are confirmed in the quotation for your order — ask through the contact page.
Do you ship to institutions abroad?
Yes, we supply colleges in India and international markets; add the item to the enquiry cart with your destination.
