Torsion Of Bars Apparatus Model HV-EXP4846
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 warrantyRange 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 materialsDescription 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. Four specimens are provided as standard, namely : Mild steel rod 460 x 5mm dia. Brass rod 460 x 5 mm dia. Aluminium alloy rod 460 x 4.76mm dia. Nylon rod 460 x 6.35mm dia.

Eccentrically Loaded Tie Apparatus Model HV-EXP4847
Features Low cost, effective teaching Self-contained Bench-mounted Combined bending and tension Three eccentricities Three year warrantyRange of Experiments To measure the vertical bending deflection of the bar and to compare with theoretical predictions. To assess the effect of eccentricity of loading.Description Sometimes in the design of a structure, a tension member has to be offset from the line of action of the force. The member then has to carry combined tension and bending loads, the latter increasing with the eccentricity of the load. The eccentricity is exaggerated to make visual appreciation of the phenomenon possible. When the load line is outside the middle third of a square tie bar, as in this experiment, the bending moment predominates and the bending deflection may be considerable. The apparatus enables both the load and eccentricity to be varied. A 9mm square section by 800mm long specimen is provided, together with dial gauge and load hanger. Different shaped specimens can be manufactured in the college workshop as required. 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.

Internal Elastic Forces Apparatus- Engineering Lab Training Systems Model HV-EXP4852
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.

Deflection of Curved Bars Apparatus- Engineering Lab Training Systems Model HV-EXP4853
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. This equipment is part of a range designed to both demonstrate and experimentally confirm basic engineering principles.

Combined Bending and Torsion Apparatus- Engineering Lab Training Systems Model HV-EXP4854
Features Low cost effective teaching Self-contained Bench-mounted Range of specimen materials Introduction to theories of failure Bending and torsional loading ratios variable 3 year warranty Range of Experiments To determine elastic failure of a specimen subjected to several ratios of bending and torsion simultaneously To compare the results with the established theories of failure Description Much of the design of parts in mechanical and civil engineering is complicated by there being biaxial or triaxial stresses for which some failure state has to be determined. Obvious examples are high pressure cylinders containing liquids or gases and concrete hinges for large bridge bearings. For more than a century, physicists, mathematicians and engineers have been proposing various theories of failure. Some theories have been attempts to explain observed failures while a few have tried to base a mechanism on fundamental properties of materials. It is evident that there is a considerable difference between the behavior of ductile and brittle materials. That apart, it is quite difficult to determine failure with sufficient accuracy in experiments designed to show which failure theory is most applicable. Hence, it is frequently found that codes of practice lay down what appears to be a somewhat empirical design method which experience has proved to be workable. This simple machine uses inexpensive test specimens made from round bar. The specimen is clamped at one end to the base bracket and at the other to a counterbalanced circular loading plate. This plate is graduated in 15° intervals. A special hanger enables pure bending, pure torque or combined loads to be applied depending on the position of the plate. The specimen deflection is measured by a dial gauge mounted diametrically opposite the load point. In the event of a specimen failure safety is ensured by set screws 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.

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, 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. Young's modulus for the strut material is derived in a secondary experiment, using the same equipment but with a specimen loaded as a beam. 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.
