Water Hammer Apparatus
Water Hammer Apparatus Technical Description The experimental set-up for the investigation of water hammer in pipes is clearly laid out on a laboratory trolley. For reasons of space, the experimental pipe section is of a spiral design. The medium used for the experiments is water. Using solenoid valves, an abrupt change in the flow speed in the pipe can be induced, this initiates a pressure pulse. A pressure vessel with a cushion of air simulates an open ended pipe such that there is a clear reflection of the pressure wave. A pressure transducer measures the pressure wave and converts it into a voltage signal. To make the pressure characteristic visible, an oscilloscope can be connected. The reflection time and closing time of the solenoid valve can be read on the oscillogram. The oscilloscope is not included.

waltenhofen pendulum
Waltenhofen Pendulum When a massive body made of conductive material moves through a magnetic field, eddy currents are induced. According to Lenz’s law, the body is then subjected to a force which is opposed to the cause of the eddy currents, i.e. the motion of the pendulum. The braking action increases with the strength of the magnetic field. If slits are cut into the body, this reduces the generation of the eddy currents.

Vibration Of A Spiral Spring
Vibration Of A Spiral Spring Features Low cost, effective teaching. Self-contained. Wall mounted. Measurement of oscillation frequency. Demonstration of Hooke's law for torsional spring. Comparison with theoretical predictions. Three year warranty. Range of Experiments To compare the experimental stiffness of a plane spiral spring with theoretical predictions. To observe if the spring exhibits a linear elastic behavior. Description Spiral springs are used to provide a restoring torque to an oscillating shaft when it rotates through an angular displacement. They exhibit similar stiffness characteristics to linear springs, except that the effect is one of torque rather than force. The stiffness of a spiral spring depends on its physical dimensions and the rigidity of the steel strip from which it is formed. The student can easily calculate the theoretical simple harmonic motion of the spring, and compare the value with simple experimental results. A range of moments of inertia of the oscillating part is provided. The wall mounted unit consists of a spiral spring coiled from a length of 25 x 0.6mm steel strip to give an effective length of 2 metres, attached to a shaft mounted in ball bearings. A cord carrying a weight hanger is wound round the shaft, and a load applied to twist the spring. Spring deflection is measured with an attached 360° scale. A cord and weight hanger are supplied. A set of discs which can be attached to the shaft change the frequency of oscillation, measured by the stop watch provided. This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles. Great care has been given to each item so as to provide wide experimental scope without unduly complicating or compromising the design. Each piece of apparatus is self-contained and compact. Setting up time is minimal, and all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. A complete instruction manual is provided describing the apparatus, its application, experimental procedure and typical test results

Universal Nibbling Machine
This machine is best suited for small batch production or when cost of press tools and dies is prohibitive. It enhances quality and productivity by doing such jobs which used to be done by skilled men and hand tools. The machine has eliminated expensive trimming dies in many modern workshops. Fabricators, Control panel manufacturers, cabinet & vehicle body makers, fan & impeller industry in addition to many others find it a most valuable asset. While the capacities indicated below are for mild steel, the machine is often used for many other materials as well. DESCRIPTION : The Sheet Metal Nibbling Machine is a rugged, sturdy and reliable multipurpose machine capable of sheet cutting & forming operations. Its verstility is best expressed by terming it the Sheet Metal Workers lathe. The working principle on which nibbling operates is the sheet is cut or formed between the fast reciprocating motion of an upper tool (powered by an electric motor and driven by an ecentric crank) and a stationery lower tool, by progressive punching, as the sheet is fed. OPERATIONS : Shearing tools are available for straight cutting, figure cutting (contour cutting) and circle cutting operations. The shearing length per cut is small and there is no wastage of materials. Nibbling is a continuous punching operation with a circular tool and is used for producing internal and external cut-outs of any shape. The workpiece does not warp but the edges produced may require filing, depending on the end use. The fixed nibbling tool is a. solid punch cutting at one side. The punch and die clearance is provided to suit the sheet thickness and the feed is controlled by the tool design. This tool, when used with the rotary nibbling attachment, enables nibbling in any direction without turning the sheet. Rectangular notching is a continuous punching operation with a square punch and die. It is used mainly for producing internal rectangular cutouts. The tool cuts in the two directions and the edges produced are clean. Universal nibbling tool consists of a round or square hollow nibbling punch, a guide pin and die. The nibbling punch cuts on all sides and with copying complates it becomes a quick and economical way to produce parts or cutouts of any shape or size. The guide pin controls the feed rate. Slot cutting is a done with a double-edged cutting tool which avoids warping of sheets. Suitable for parting of sheets, cutting small strips and slots. The upper tool has to be changed for each slot width while the bottom tool is adjustable. Louver cutting is a combined shearing and forming operations. The sheet is first cut and then the louver is formed with the forming part of the tool. The length of louvers produced is independent of the length of the tool. This operation as well as beading, folding and flanging are completed in 2 to 3 passes. After every pass the tool is fed further towards the sheet. Beading is a forming operation used for the stiffening of sheets. Folding is also a forming operation and by double folding, channels may be made for housing of electrical writing etc. Flanging is forming operation very commonly used on sheet metal parts. 0° to 90° flanging is possible by changing the lower tool only. 2-3 passes are generally required and intermediate annealing may be necessary in some cases to get the correct angle of flange. Like all other forming operations, the circle guiding attachment for straight feeding attachment is necessary for producing circular or straight flanges. However, a separate tool which uses the edge of the workpiece for guidance is available for free hand flanging of any shape. Dishing or peening is a mechanical hammering operation used for forming dished parts like tank bottoms. The quality of dishes formed depends on the skill of the operator. Large hole punching is possible with special punch and die sets. Round or square holes such as needed for fixing lamps or push buttons etc. on panels are produced on these low tonnage machines by providing a shear on the punch. Inner circle cutting Available for circles from 100 mm dia meter up to a maximum circle dia meter-the size being 80% of throat depth of the corresponding model chosen. Pre-hole in the centre is necessary for sheet thickness above 2 mm Accessories : Complete electricals, a set of straight cutting tools with the holders, necessary keys, spanners for the operation of machine, feeler gauge & operation manual form the std. accessories supplied with the machine.
