Simple Suspension Bridge
The Simple Suspension Bridge (Product Code: SLE/EG/06) is a model bridge experiment for studying how the tension in a suspension cable changes as loads are placed on the deck. Students predict the tension from theory, then compare it with the value measured by a load cell that can be logged through the Structures Platform. Additional masses let them apply either a single point load or a uniformly distributed load (UDL). The model is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as lab equipment for technical institutes and civil engineering departments.
Key Details
| Parameter | Detail |
|---|---|
| Type | Suspension bridge model for cable tension experiments |
| Measured quantity | Cable tension under applied load, via a load cell |
| Load types | Single point load and uniformly distributed load (UDL) |
| Included masses | Additional masses for the UDL and point load cases |
| Data connection | Load cell connects to the USB interface hub of the Structures Platform for computer display and data acquisition |
| Theory covered | Simplified parabola-based equation and a more realistic theory based on the model |
Typical Use
A session usually starts with the unloaded bridge, so students can see how much of the cable tension already comes from the deck's own mass. They then add a point load at different positions, and afterwards spread the masses along the deck as a UDL, recording the tension from the load cell each time. Comparing the readings with the simple parabolic cable equation and with the more realistic model-based theory shows where the simpler assumption holds well and where it drifts.
One of the most memorable results is the overwhelming influence of the deck mass compared with relatively small live loads such as vehicles crossing a real bridge. That insight helps civil engineering students understand why long-span bridges are designed as they are. With logging through the Structures Platform, the model fits neatly into a modular set of engineering lab equipment in India for structures and bridge engineering teaching.

Frequently Asked Questions
What does the load cell measure?
It measures the cable tension, which changes as students apply loads to the bridge.
Are masses included?
Yes, additional masses are included so students can apply a uniformly distributed load and a single point load.
Which theories are compared?
A simplified parabola-based equation and a more realistic theory based on the model itself.
Can it be used without a computer?
Our description covers display through the Structures Platform hub only. Please contact us to confirm whether a standalone readout option suits your lab.
What are the span and mass values?
These figures are not given in our current product text; we can send full technical data on request.
What warranty and certificates are available?
The warranty is confirmed in the quotation, and any need for load cell calibration paperwork should be discussed with us.
Do you take tender and export orders?
Yes. We quote for institutional tenders in India and for buyers in international markets.
