Plastic Bending of Portals (Product Code: SLE/EG/26) is a structural experiment in which a specimen portal frame is loaded beyond its elastic limit until plastic hinges form and it collapses. Load cells apply and measure vertical, horizontal or combined loads through cables held at 90 degrees to the portal, while precision indicators track how the frame deforms. The apparatus shows how a building can yield yet still carry load long enough for people to leave safely. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, an engineering lab equipment manufacturer supplying civil and structural engineering departments.

Key Details

Typical Use

Before loading, students predict the collapse loads for the chosen load case using textbook plastic analysis, identifying where hinges should form in a fixed-base portal. They then increase load through the cable-and-load-cell system, recording force and deformation. The response starts out linear, then flattens as the first hinge forms and the frame begins to deform permanently, until a mechanism develops and the portal can take no more load. Because the cables stay at 90 degrees to the portal, the load direction is preserved even as the frame sways, so the measured collapse load can be compared fairly with prediction.

Repeating the test with vertical only, horizontal only and combined loads lets the class plot an interaction diagram and see which failure mode governs for each combination. This builds real understanding of ductility and reserve strength, and why designers value them. The rig is well suited to final-year undergraduate and postgraduate structures work and to technical institutes teaching limit-state concepts.

Redundant Truss Next Generation Structures (Product Code: SLE/EG/04) is a truss experiment used to compare a statically determinate frame with a statically indeterminate one in university and engineering college structures labs. Strain gauges on every member, a precision deflection indicator and an extra ‘redundant’ member engaged by a thumbscrew let students test both cases on the same frame. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as engineering educational equipment for structural analysis courses.

Key Details

What Is the Redundant Truss Used For?

The practical runs in two halves. With the redundant member disengaged, the frame is statically determinate: students apply load at the Joint Boss with the hand-operated load cell, read the strain in each member and convert it to member force, then check the values against a method-of-joints calculation. They also note the deflection on the precision indicator. This first half confirms the reliability of the textbook equations and the accuracy of the experimental results.

Turning the thumbscrew then brings the extra member into action and the same loads are repeated. Now the forces can no longer be found from equilibrium alone, so students predict them with the strain-energy method and compare deflection for both cases, seeing how the redundant member shares load and stiffens the frame. For colleges buying engineering lab equipment in India, it bridges determinate and indeterminate structures in one bench-top module.

What to Specify When Ordering

• Whether you already have the Structures Platform, whose interface hub is needed for computer display and data acquisition (it is a separate item).

For more structures apparatus, open our General Products listing.

Frequently Asked Questions

What makes the truss ‘redundant’?
The Redundant Truss Next Generation Structures frame has an extra member that a simple thumbscrew engages. With it engaged, the frame becomes statically indeterminate, so member forces can no longer be found from equilibrium alone and need a method such as strain energy.

How are member forces measured?
Each member of the Redundant Truss Next Generation Structures carries strain gauges. Their signals pass to a strain gauge amplifier, which connects to the interface hub of the Structures Platform for computer display and data acquisition.

Does it need the Structures Platform?
Yes, for computer display and data acquisition. The Redundant Truss Next Generation Structures connects through a strain gauge amplifier to the Structures Platform interface hub, and the platform is listed as a separate item.

Is the strain gauge amplifier included?
The current Redundant Truss Next Generation Structures listing does not confirm whether the strain gauge amplifier is included. Please contact us before ordering and we will state exactly which parts your quotation covers.

What is the load capacity of the load cell?

Frame Deflections And Reactions (Product Code: SLE/EG/05) lets students load a portal-type frame and measure how it sways and what reactions develop at its base. One of two frames is fitted between two supports; load cells in the supports read the bending moment and horizontal reaction at the foot of each upright, and a precision indicator records sideways deflection at the beam-to-upright junction. A Vernier caliper is included for cross-section measurement. The module is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as structures lab equipment for college and university civil engineering courses.

Key Details

Typical Use

Students begin with calculation. Using textbook frame analysis they predict the base reactions and fixing moments for a given load position, and decide whether the frame should sway and by how much. They then set the supports using the pointers and platform scale, apply the load to the beam and read the support load cells and the sway indicator. A symmetric load on a symmetric frame should give little or no sway; moving the load off-centre, or changing to the second frame, shows sway appearing even though no sideways force is applied.

That is the key lesson: the module helps students understand the two causes of frame sway other than direct loads, which many find counter-intuitive on paper. Measuring the member sizes with the supplied caliper keeps the stiffness calculations honest. For departments building a set of mechanics lab equipment for structural analysis, it links single-beam work to full frame behaviour.

Frame Deflections And Reactions is manufactured by Jain Scientific Equipments Private Limited, an Ambala, Haryana company that markets its products as ScienceLab. See our company profile for more about the organisation.

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

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.

Bending Moments In A Portal Frame (Product Code: SLE/EG/07) is a strain-gauged portal frame that lets students measure bending moments around a real frame and draw its bending moment diagram from test data. The frame is held between two fixing blocks and can take vertical, horizontal or combined loads, plus loads on moment arms that mimic cantilevered floors. A precision indicator records sway. The module is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, whose range of vocational training and university lab equipment covers structures, fluids and materials.

Key Details

Typical Use

Students first measure the frame section with the Vernier caliper and use textbook methods, such as moment distribution or the flexibility method, to predict bending moments at the gauge positions and the expected sway. They then apply the chosen load case and read the strains, converting each to a bending moment. Because the gauges sit at key points around the portal, the measured values can be joined up into a bending moment diagram and laid directly over the calculated one.

Running several load cases shows how the diagram changes shape: a vertical load on the beam, a horizontal load at eaves level, the two combined, and loads on the moment arms that represent floors projecting inside or outside the frame. Comparing sway with prediction completes the picture. This makes it a valuable piece of engineering educational equipment for building-frame analysis in civil and structural programmes.

Manufacturer

The module is made by Jain Scientific Equipments Private Limited, the Ambala, Haryana company behind the ScienceLab brand and a registered MSME manufacturer (Udyam UDYAM-HR-01-0003714). International consignments are shipped under Importer-Exporter Code AAECJ8618A issued by the DGFT. Read about us on the company profile page.

The Suspended Beam Bridge (Product Code: SLE/EG/08) models a cantilever bridge in which two outer anchor sections carry a short central span hung between their cantilever tips. Load cells in the supports and within the bridge measure both the support reactions and the internal reactions where the suspended span meets the cantilevers, so students can test textbook predictions for a statically determinate bridge that can still achieve a large central span. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a technical educational equipment manufacturer for civil engineering and polytechnic laboratories.

Key Details

Typical Use

Students set out the four supports using the pointers and platform scale, then place a load at a chosen point along the deck. From the load cells they read the four support reactions and the two internal reactions at the joints between the cantilevers and the suspended span. Using statics alone they predict the same values, since the hinge-like joints make the bridge statically determinate, and then compare. Moving the load step by step across the bridge lets the class build influence lines for each reaction.

The model explains why this form of bridge has been used for long spans: the suspended section lets the structure span far while remaining simple to analyse and less sensitive to support settlement. It is an engaging way to link theory with real bridge design, and suits departments buying lab equipment for technical institutes that teach bridge engineering and structural analysis.

Manufacturer

Supplied under the ScienceLab name, this bridge model is manufactured by Jain Scientific Equipments Private Limited, located in Ambala, Haryana. Further information is on our company profile.

Continuous and Indeterminate Beams (Product Code: SLE/EG/09) is a beam experiment set that takes students from simple, statically determinate beams to continuous and statically indeterminate beam systems. It combines a ‘rigid’ heavy beam, a light ‘flexible’ beam, a slide-mounted precision deflection indicator and two additional supports, one of which can act as a simple, clamped or sinking knife-edge support. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, an engineering lab equipment manufacturer supplying strength of materials and structures laboratories.

Key Details

Typical Use

The first group of experiments uses the heavy ‘rigid’ beam on two simple supports. Because this beam barely deflects, students can focus on statics: taking moments, applying the principle of superposition and working with uniformly distributed loads, then confirming their reaction calculations. Once those basics are secure, they change to the light ‘flexible’ beam, where deflection becomes large enough to measure with the slide-mounted indicator.

The second group of experiments introduces the extra supports. Adding a third support makes the beam continuous and statically indeterminate; the fixing-moment support shows the moment developed at a built-in end; and the universal support, set as a sinking knife edge, lets students see how settlement of one support redistributes the forces. These exercises bring methods such as the three-moment equation or compatibility of deflections to life, making the set useful mechanics lab equipment for second- and third-year civil and mechanical courses.

Manufacturer

Jain Scientific Equipments Private Limited of Ambala, Haryana manufactures this beam set and trades as ScienceLab. You can read more about the company in our company profile.

Plastic Bending Of Beams (Product Code: SLE/EG/10) is an experiment in which a specimen beam is loaded at mid-span until it yields and forms plastic hinges, under three different end conditions: simply supported, fixed, or propped cantilever. A load cell assembly both applies and measures the force, a precision indicator tracks deformation, and one support runs on roller bearings to allow horizontal movement. It helps students see how a structural element can yield yet keep carrying load. The apparatus is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as lab equipment for college and university structures courses.

Key Details

Typical Use

For each end condition, students first sketch the elastic bending moment diagram, work out the load at first yield, and predict where plastic hinges will form and what load will cause collapse. They then fit a specimen, apply load at mid-span with the load cell assembly and record force against deformation. A simply supported beam fails once a single hinge forms under the load; a propped cantilever or a fixed beam needs further hinges before it becomes a mechanism, so it carries noticeably more load beyond first yield.

Comparing the load at first yield with the collapse load leads to the ratio between yield moment and fully plastic moment, the form or shape factor, and shows how it gives an extra margin of safety. Students leave with a clear, physical sense of why ductile structures give warning before failure, which is central to modern design codes. It is well matched to departments investing in engineering educational equipment for advanced strength of materials.

Frequently Asked Questions

Which end conditions can be tested?
Simply supported, fixed and propped cantilever, allowing students to compare hinge positions and failure loads.

Where is the load applied?
At mid-span, through a load cell assembly that both applies and measures the force.

Why does one support have roller bearings?
They let that support move horizontally, so the beam is not restrained axially when that is not intended.
