Features Low cost effective teaching Self-contained Wall-mounted Demonstrates Hooke's Law Measurement of spring stiffness 3 year warranty Range of Experiments To test the relationship between the load applied and the change in length of a spring (Hooke's Law) To determine spring stiffness For more advanced courses, the dependence of spring stiffness on the wire diameter, spring diameter, length, number of turns and material. Comparison with theoretical estimate. Description Springs are used in engineering to store energy or to provide restoring forces. Both compression and tension springs may be encountered. The deflection of a spring depends on the load applied to it, an observation enshrined in Hooke's Law. Applications of springs are found in spring balances which indicate loads by measuring spring deflections and in car suspensions where they absorb energy caused by wheel vertical movement due to potholes and bumps. The equipment is designed to be fitted to a wall. It is used to test tension springs up to 200mm in length. The maximum spring diameter is 38mm. A weight hanger is used to apply a load to the spring. Spring deflection is measured with a sliding scale which can be easily re-zeroed to suit the length of the spring. A spring, weight hanger and weights are supplied with each piece of equipment. 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.

Features Low cost effective teaching Self-contained Wall-mounted Simulates strains for a bolt stressing a tube Determination of stiffness of tension and compression springs 3 year warranty Range of Experiments To determine the stiffness of springs in tension and compression To investigate a self-straining system similar to a bolt in a tube. In particular to measure the reduction in length of the "tube", and the forces in the springs To measure the increase in length and forces in the system due to applying an external tensile load Description The apparatus is a self straining system analogous to a bolt stressing a tube, enabling the final overall deflection of the system to be determined. It consists of a frame in which there are two springs. A tension spring with means of adjusting its length has a disc at its lower end. Between this disc and the top of the frame is fitted a compression spring. A weight hanger attached to the disc enables the two springs to be loaded. The stiffness of the two springs is different so that an overall deflection is induced. The two springs can be installed separately in the frame so that the stiffness of each can be determined. In the case of the compression spring, it is necessary to apply loads through a cord and pulley arrangement. A graduated scale alongside the disc shows the deflection of the spring(s). Excellent results are achieved due to the low friction of the equipment. This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles.

Setting up time is minimal, all measurements are made with the simplest possible instrumentation, so that the student involvement is purely with the engineering principles being taught. A piece of material in compression is called a strut. If it is short and stubby it will fail by compressive stress, but if it is slender the failure mode is that of buckling. The load at which the strut buckles depends on the way in which the ends are restrained. Built-in ends resist buckling more than ends which are free to move. The apparatus shows how the buckling mechanism occurs, and the influence of the end restraint. The apparatus is rigid and wall mounted. It can test struts between 0.75 m and 1 m in length with either pivoted or built-in ends. Axial load is applied to a load hanger linked by cables to the yoked ram whose travel can be pre-set to prevent permanent damage to the strut. A lateral load can be applied at any position to the strut. Seven mild steel specimens are supplied as standard. A dial gauge is supplied to measure strut deflection. With this equipment, an in depth study can be made of the factors that effect the buckling of a strut; its length, cross section, material and end restraint.

Torsion Of Bars Apparatus Features Low cost effective teaching Self-contained Bench-mounted Direct application of torque and measurement of angle of twist Determination of modulus of rigidity for different materials 3 year warranty Range of Experiments To measure the angle of twist produced by torsional loads for various specimens and verify that the relationship is linear. To determine the modulus of rigidity for specimens of various materials Description Torsional loads are common in power transmission shafts, and in certain cases can also occur in structural members. It is thus very important that engineers understand the relationship between the torsional load applied to a particular beam and the angular twist produced. Also, engineers must understand how this relationship varies with the material from which the beam is made and its cross sectional polar moment of area. This apparatus allows these relationships to be investigated directly. Specimens are rigidly held in a clamp fixed to one end of the base frame of the apparatus. A short shaft mounted in the bearing has a three jaw chuck facing the clamp and a torsion head at the outward side. The torsion head and chuck are used to apply torsional loads to the specimen. A rotation scale and pointer can be attached to any point on the specimen's length to find the angle of twist of the specimen.

Deflection of Curved Bars Apparatus Features Universal machine Compact, bench mounted Four specimens supplied: Circular ring, Semi-circle, Quadrant and Davit Measurement of oscillation frequency Measurement of horizontal and vertical deflections by dial gauges Demonstrates strain energy concepts Three year warranty Range of Experiments To experimentally determine the vertical and horizontal deflections of various curved bars whose cross sectional dimensions are small compared with the bar radius. To compare with theoretical estimates using strain energy theories such as Castigliano's first theorem. Description The theoretical deflections of curved shapes are most easily found by applying strain energy ideas, such as Castigliano's first theorem. The shapes chosen provide a relatively easy introduction to the use of such techniques, which students often seem to find difficult to grasp. A bench mounted base supports a curved bar formed into a ring, semi-circle or quadrant/davit. Loads are applied by specially designed weight hangers so that the specimen bends. Horizontal and vertical deflections are measured by dial gauges rigidly attached to the base. The bars can be readily changed and the position of the dial gauges relocated to measure the deflections of the new configuration. Bars, weight hangers and a set of weights are supplied.
