This versatile geometry tool set includes a colorful plastic-

• The balance assembly is an articulated parallelogram, linked to a load cell. 
• The balance assembly is mounted on a carrier that runs along the rails of the Flume.
• The parallelogram resists bending moments so that only the force on the model is transmitted to the load cell.
• The display unit displays the force measured by the load cell. 
• This unit is hung on the flume.

• This kit includes two long lengths of smooth-walled pipe with multiple pressure tappings and a Pitot traverse. 
• The pipes connect to the inlet, so it becomes a suction fan for tests on the pipes.
• A Pitot traverse fits at the end of one long pipe to allow you to measure the velocity profile across a pipe and calculate the theoretical flow.  
• The pipe tappings connect to a multiway pressure display. 
• The multiple pressure tappings along the long pipes allow you to measure the pressure drop and therefore losses along them. 
• A probe mounts in an assembly so that it moves axially through an additional nozzle to measure its axial pressure profile. 
• This allows a comparison with the flow found from the nozzle and the orifice plate included with the kit.
• The kit includes three different fittings: two elbows and a bend, that each fit between the long pipes to test the pressure drop and therefore loss caused by the fitting. 

• Bench-top test set that allows students to investigate the operation and performance of a single centrifugal pump and two centrifugal pumps in both series and parallel.
• The pumps draw water from the clear acrylic reservoir.
• The apparatus comprises one variable speed centrifugal pump and one fixed speed centrifugal pump, together with two bearing-mounted motors driving each pump independently. 
• The water travels through a series of valves to be delivered to a flow and temperature measurement device. 
• Then returns to the reservoir for re-use, keeping water use to a minimum.
• Adjustable inlet and delivery valves allow students to create different operating conditions.

• A self-contained, fully instrumented, educational two-shaft gas turbine. 
• A steel frame holds a gas generator, power turbine, combustion chamber, oil and fuel tanks, pumps, ancillaries and guards.
• Air passes through a calibrated nozzle and air box, into a compressor, then into the combustion chamber. 
• A pump transfers fuel from the fuel tank to spray through a special nozzle into the combustion chamber. 
• A high-energy spark ignites the air and fuel mixture, that flows to a gas generator turbine.  
• These is an instrumentation and control panel with schematic diagram. 
• The clearly labelled control panel with mimic diagram includes the instrument displays, controls and warning lights.
• The combustion chamber gives excellent combustion, low pressure loss and good flame stability over a wide range of conditions. 
• A fuel flow control valve on the instrumentation and control panel regulates the turbine speed.
• This design reduces the possibility of overspeed.

• The Spring Testing Apparatus uses a fundamental variable mass and scale measurement to test springs. 
• It shows students how to find the properties of a spring and proves some basic laws of physics. 
• The back of the frame has a storage area for springs and masses.  
• The apparatus is a compact metal frame with adjustable feet so the user can make the apparatus level. 
• The front of the frame has a metric scale each side of a large slot, where the test spring hangs. 
• It is also a useful tool for a workshop, to check the properties of a spring before it is used, or after it has been used.
• Supplied with the apparatus is a set of extension or ‘tension’ springs. 
• The user can compare different spring rates with different spring sizes to fully understand the basic rules of spring design. 

• The compact Strain Gauge Trainer fits on a bench or desktop. 
• Contains everything needed to show students how resistance strain gauges work on three different structures. 
• Students use the small set of masses to load the bending and torsion systems, and the large set of masses to load the tension system. 
• They use theory and known dimensions to calculate the stresses and strains and compare them with the strains measured by the strain gauges. 
• The bending system uses gauges to measure direct tensile and compression strain. 
• The torsion system shows the use of shear/torque strain gauges. 
• Students can also connect and compare the performance of quarter, half and full-bridge strain gauge connections for each structure. 

• A sixteen channel instrument that connects to industry standard strain gauges to give direct readings of strain. 
• For use with most types of metal-foil strain gauges, the Digital Strain Display connects to most types of strain bridge connections to give direct readings of strain. 
• The Digital Strain Display accepts up to 16 channels from strain gauges connected in quarter, half or full bridge. The display is fully programmable to match the strain gauges and their bridge connections. 
• The display includes precision internal ‘make-up’ resistors to work with half bridge connections if needed. 
• Two channels include additional individually adjusted dynamic outputs. 
• Also supplied is a tool that crimps the connectors to the cable. The connectors are self-locking, reliable, secure and need no soldering. 

• A self-contained bench mounting experimental apparatus to enable students to investigate the effect of pressure on the surface profile of a diaphragm and also the distribution of circumferential and radial strains.
• Two heavy flanges clamp the edge of the diaphragm to provide built-in edge conditions. 
• The area directly under the diaphragm contains oil.
• Each strain gauge circuit is a full bridge, with high-stability resistors. 
• The signals from each strain gauge are shown on a digital display.  
• Eight strain gauges are cemented to the top surface of the diaphragm in various positions and at different radii.
• A digital dial gauge is fitted to a digital position indicator. The dial gauge can be traversed across the diaphragm to measure its surface profile. 

• A bench mounting apparatus to allow the stresses and strains of a pressurised thin walled cylinder to be investigated and analysed.
• The apparatus consists of a thin-walled aluminium cylinder, held in a robust frame. 
• The frame holds the cylinder so that it is free to move along its axis. 
• The cylinder contains oil. 
• To stress the cylinder, students use the hydraulic handpump to pressurise the oil. 
• Strain gauges on the cylinder surface measure strain, while a gauge and electronic sensor measure hydraulic pressure.

• The spring is of the same heavy-duty design as those used in vehicle suspensions. 
• Two metal ‘bosses’ hold the spring securely in the testing machine, which compresses the spring. 
• The digital indicator of the testing machine measures the change in spring length (displacement) for a given change in applied force. 
• Students use the displacement and force values to find the actual spring rate and compare it with the theoretical value, based on the spring dimensions. 
• The experiment helps to show Hooke’s Law for the relationship between force and displacement on a spring.

• The indenter uses a hardened steel ball in a holder that pushes down onto a suitable test specimen and creates a small dent. 
• Using the dimensions of the dent, the indenter ball and the force applied gives the Brinell hardness number of the specimen material.
• The hand-held magnifier has a measurement scale or ‘graticule’ for accurate measurent of the dent.  

• Disc springs are common in many industries. 
• The main applications are those that require a small deflection for high force levels. 
• Disc springs can easily be stacked in a variety of arrangements to vary their deflection rates.
• The disc guide is fitted to the lower compression plattern and the compression cylinder to the upper plattern. 
• The disc springs are stacked in the desired combination on the disc guide. 
• The pump is operated to rais the ram and compress the springs.
• The spring discs can be stacked in parallel, in series or in a combingation of series and parallel.

• A set of five trays and lids.
• These trays and lids are useful to safely store ancillaries, writing materials or A4 size printed material. 
• Identical to those used for the kits, so they fit and stack in the same way.
