Quick answer. Sort every rig by regime before you order: elastic, plastic or time-dependent. The SOM items fall into three groups. Elastic rigs, such as beam deflection, torsion, springs, wires and strain gauges, give a straight-line graph in one session, so buy several and let a class rotate. Destructive machines, such as the plastic torsion tester, universal testing machine, Izod impact and buckling tester, consume a specimen each run, so one usually serves for demonstrations. Fatigue and creep tests run for hours or days and belong in project work, so buy them only if your syllabus examines them.
About forty items, coded SOM-0001 onwards - the experiment set of a strength of materials laboratory. Beams: deflection of beams, an advanced beam testing apparatus, deflection of curved bars, curved beams and test beams. Torsion: torsion of bars, torsion of a spiral spring, and separate elastic and plastic torsion testers. Stability: critical load on struts, critical condition of struts and a buckling tester. Springs and wires: extension and compression of springs, extension of wires, compound wires and an internal elastic forces apparatus. Combined and pressurised: combined bending and torsion, a thick cylinder apparatus and a diaphragm. Strain measurement: electrical resistance strain gauges, their calibration and strain gauge studies. Time-dependent failure: creep and fatigue, including a rotating fatigue machine. Machines: a universal testing machine, a fatigue testing machine and an Izod impact testing machine. Structures - trusses, an arched bridge and a suspension bridge - also appear here.
Three notes on our catalogue text. One record is listed as "Hook Low", which is the Hooke's Law apparatus - the term you are probably searching for, and one of several places in this catalogue where a possessive apostrophe has been stripped by an import. Several records carry one-word names - creep, strain, bending, diaphragm, truss - which identify a property rather than a product, so ask us what each is. And two records in this listing, a lastometer and a leak proofness tester, are leather testing instruments that have been copied in from the leather testing equipment range; they are not strength of materials apparatus. Quote the code and the full product name together and have both confirmed on the proforma invoice.
Strength of materials is three subjects wearing one name, and the apparatus divides the same way. Knowing which of the three a given rig belongs to tells you what result it can produce and how long it will take - and it is the quickest way to match this listing to a syllabus.
| Regime | What is measured | Apparatus here | Practical length |
|---|---|---|---|
| Elastic | Recoverable deformation, and the constants that govern it - Young modulus, modulus of rigidity, Poisson ratio. This is where theory and experiment agree closely, which is exactly why it is taught first | Beam deflection, curved bars, torsion of bars and springs, extension of wires and springs, elastic torsion tester, thick cylinder, strain gauges | Short. Several readings and a straight-line graph in one session |
| Plastic and ultimate | Permanent deformation, yield, and failure. The specimen is destroyed | Plastic torsion tester, universal testing machine, Izod impact, buckling tester | Short per specimen, but each run costs a specimen |
| Time-dependent | Failure under repeated or sustained load, which is how real components actually fail | Fatigue testing machine, rotating fatigue machine, creep apparatus | Hours to days. These cannot be run inside a practical slot and need a counter, an auto-stop and a log |
The practical consequence for a purchase: a department can run the elastic experiments every week with a class, the destructive ones as demonstrations with a few specimens, and the time-dependent ones as project work. Buy accordingly - several elastic rigs so a class can rotate, one destructive machine, and one fatigue or creep machine if the syllabus examines them at all.
A beam deflection apparatus looks like the simplest rig in the laboratory, and it has one failure mode that quietly ruins results. The deflections being measured are small - often fractions of a millimetre - and if the frame, the supports or the dial gauge mounting deflect by a comparable amount, the experiment measures the apparatus rather than the beam.
So ask: how stiff and how heavy is the frame, and must it be bolted down; how are the supports made - knife edges and rollers that genuinely allow rotation and longitudinal movement, or clamped blocks that introduce an unintended fixed end; how is the dial gauge mounted, and is its mount independent of the loaded span; and what resolution the gauge offers against the deflections expected. Ask also what beams are supplied - the exercise is far better with several materials and sections of known dimensions, since the second moment of area is calculated from measured dimensions and a nominal section is not good enough.
Buckling is not a strength problem but a stability problem, and that is the lesson: a slender strut fails at a load far below the material strength, and the failure depends on the end conditions rather than only on the material. The critical load apparatus and the buckling tester exist to show it, and the end fixings - pinned, fixed, one of each - are the experiment, so ask what end conditions can be set and how repeatably.
And the safety point, because this is the one rig in the listing that surprises people: buckling is sudden, and a strut released at the critical load can fly out of the apparatus. Ask about a guard or a shield, a retaining arrangement at the ends, and where the operator stands. It is a trivial addition and it should be specified rather than improvised.
The strain gauge items are the most valuable in this listing for a student heading into industry, because a bonded resistance gauge is how real structures are measured. They also demand more care than anything else here, and the questions reflect that.
A gauge measures strain at a point on a surface it is bonded to, through a bridge circuit that resolves changes of a few parts per million in resistance. The consequences: the bond is the measurement - a gauge imperfectly bonded reads low and drifts, and bonding is a skill that takes practice, so ask what adhesive, surface preparation materials and practice coupons are supplied and what they cost, because they are consumables; lead resistance and temperature both shift the reading, so ask how the bridge is configured, whether three-wire connection and a dummy gauge for temperature compensation are provided, and whether the indicator has a zero and a calibration facility. The calibration apparatus in this listing exists precisely to let a student verify a gauge factor rather than take it on trust, which is why it is worth having alongside the gauges.
Fatigue and creep run long. A rotating fatigue test to failure can take hours and a creep test days, so the question is not what the machine measures but whether it can be left: ask for a cycle counter, an automatic stop at specimen failure, a guard that contains the broken specimen, and a logging arrangement for creep, since a creep curve read by hand over three days will have gaps in it. Ask also what specimen sizes and materials are used and what they cost, because these are the most specimen-hungry experiments in the laboratory.
The thick cylinder apparatus is a pressure vessel in miniature. It demonstrates the radial and hoop stress distribution that a thin-cylinder analysis cannot give, and it holds real pressure to do so. Ask the maximum working pressure, what relief device is fitted and where it discharges, how the pressure is generated and read, and what shielding surrounds the cylinder. As with every pressurised rig, ask whether the vessel carries a certificate and what your own authority requires.
Three records here are testing machines rather than teaching rigs: a universal testing machine, a fatigue testing machine and an Izod impact machine. They are the right instruments for this laboratory, and they are specified in much more detail - capacity, accuracy class, verification certificate, fixtures, notch preparation, low-temperature impact - in our universal testing machines and tensile testing machines listings. If you are buying a machine rather than an experiment, read those pages and quote from them; if you are buying the teaching set, the experiments on this page are the ones that produce a graph a student can plot against theory.
Structures apparatus - trusses, arches, suspension bridges and frames - also appears both here and in the machines listing, where the demountable-or-fixed question is set out. And for the dynamics side of mechanics, see models for theory of machines.
For each rig: the experiment and the quantities measured, with the resolution of each instrument against the magnitudes expected; frame stiffness, mass and whether bolting down is required; support and end-fixing arrangements; specimens supplied - material, dimensions and quantity - and the price of further sets; dial gauges, indicators and whether mountings are independent of the loaded member; for strain gauge work, adhesive, preparation materials, practice coupons, bridge configuration and temperature compensation; for fatigue and creep, cycle counter, auto-stop, guarding and logging; for the thick cylinder, working pressure, relief, shielding and any certificate; guarding on anything that fails suddenly; bench or floor mounting and footprint; the worksheets supplied; nominal voltage, frequency and plug pattern; consumables and spares with prices; and the warranty, commissioning and local service position. For any certification stated here, contact us for the latest copies of the relevant certificates before you tender on it.
The full set is listed under mechanical lab equipments. For a quotation, send us your syllabus experiment list and tell us the destination country, the class size in one practical session and whether fatigue or creep is examined - that last answer changes the shape of the order.
Buy by regime. The elastic experiments measure recoverable deformation and the constants behind it, Young modulus, modulus of rigidity and Poisson ratio, where theory and experiment agree closely, so a department can run them every week; several rigs let a class rotate. The destructive ones are short per specimen but cost a specimen each run, so one machine used for demonstrations is usually enough. Fatigue and creep cannot be run inside a practical slot. When you ask for a quotation, tell us your class size and whether fatigue or creep is examined, because that answer changes the shape of the order.
A stiff frame. The deflections measured are small, often fractions of a millimetre, and if the frame, supports or dial gauge mounting deflect by a comparable amount, the experiment measures the apparatus rather than the beam. Ask how stiff and heavy the frame is and whether it must be bolted down; whether the supports are knife edges and rollers that genuinely allow rotation and longitudinal movement, or clamped blocks that create an unintended fixed end; and whether the gauge mount is independent of the loaded span. Ask also for beams in several materials and sections, measured rather than nominal.
With a guard, yes. Buckling is a stability problem rather than a strength problem: a slender strut fails at a load far below the material strength, and the failure depends on the end conditions, pinned, fixed or one of each, which are the experiment. Ask what end conditions the critical load apparatus and buckling tester can set and how repeatably. Then the safety point that surprises people: buckling is sudden, and a strut released at the critical load can fly out of the apparatus. Ask about a guard or shield, a retaining arrangement at the ends and where the operator stands, and specify it rather than improvise.
More than the instrument. A bonded resistance gauge measures strain at one point through a bridge circuit that resolves changes of a few parts per million in resistance, so the bond is the measurement: an imperfectly bonded gauge reads low and drifts, and bonding takes practice. Ask what adhesive, surface preparation materials and practice coupons are supplied, since they are consumables. Lead resistance and temperature both shift the reading, so ask about three-wire connection, a dummy gauge for temperature compensation, and a zero and calibration facility. The strain gauge calibration apparatus lets students verify a gauge factor rather than trust it.
They have to be, so ask whether they can be. A rotating fatigue test to failure can take hours and a creep test days, so the question is less what the machine measures than whether it can run unattended. Ask for a cycle counter, an automatic stop at specimen failure, a guard that contains the broken specimen, and a logging arrangement for creep, since a creep curve read by hand over three days will have gaps. Ask also what specimen sizes and materials are used and how further specimens are supplied, because these are the most specimen-hungry experiments in the laboratory.
Because of catalogue import faults. One record is listed as Hook Low, which is the Hooke's Law apparatus. Several records carry one-word names, such as creep, strain, bending, diaphragm and truss, which identify a property rather than a product, so ask what each one is. A lastometer and a leak proofness tester are leather testing instruments copied in from that range. The universal testing, fatigue testing and Izod impact machines are specified in more detail in the universal and tensile testing machine listings, and structures apparatus also appears in the machines listing. Quote the code with the full name.
