Simple Wheel and Axle Pulley Set, Two Sizes Included

  • The IEC 'Tensile Testing Machine' is a simple but effective system of measuring the tensile strength of metals. Wire is used so that the forces involved are small and can easily be applied in the classroom.
  • The machine uses an accurate dial indicator (resolution of 0.01mm) to measure stretch (extension) and uses a set of normal slotted weights to apply tensile forces to the various wires.
  • The machine provides 3 different anchor points for the wires so that, effectively, the wires can be tested at 3 different lengths.
  • The machine is supplied with rolls of .037mmD copper wire, 0.32mmD brass wire and 0.28mmD iron wire. NOTE:: The 9x50g and / or 9x100g slotted weight sets are not supplied with the machine.

Mechanics and Fluids form a core part of physics education, focusing on motion, forces, energy, pressure, and the behaviour of liquids and gases. Laboratory experiments in this field help students understand fundamental principles such as Newton’s laws of motion, momentum, friction, pressure, buoyancy, viscosity, and fluid dynamics. These concepts are essential for studying engineering, physics, environmental science, and many applied scientific disciplines.

Mechanics and fluids apparatus allow students and researchers to observe how forces influence motion and how fluids behave under different physical conditions. Typical laboratory equipment used in this area may include force meters, pulleys, inclined plane apparatus, friction demonstration systems, density measurement tools, pressure demonstration equipment, hydraulic models, and fluid flow apparatus. These instruments enable practical investigation of mechanical principles such as acceleration, equilibrium, and energy transfer, as well as fluid behaviour including pressure variation, flow resistance, and buoyancy.

Where laboratory glass components are used in fluid experiments, borosilicate glass such as BORO 3.3 is commonly preferred due to its strong chemical resistance and thermal stability. Relevant standards for laboratory glass materials may include ISO 3585 for borosilicate glass 3.3 properties and ASTM E438, which specifies requirements for glass used in laboratory apparatus. In experiments that require volumetric measurement of liquids, ASTM E694 may also apply for volumetric laboratory glassware.

Some mechanics and fluid experiments may involve electrically powered measuring instruments or sensors, which covers safety requirements for electrical equipment used in laboratory measurement and testing environments. Manufacturing and product quality systems for laboratory apparatus are also commonly aligned with ISO 9001 quality management standards.

At LabChoice Australia, we supply mechanics and fluids laboratory equipment designed for school science laboratories, university teaching environments, and educational demonstration setups. Our range supports clear visualisation of physical principles while providing durable and reliable apparatus suitable for repeated classroom use.

Practical experiments in mechanics and fluid dynamics help students connect theoretical physics concepts with real-world observations. By measuring motion, forces, pressure, and fluid behaviour directly in the laboratory, learners develop a deeper understanding of the physical laws that govern movement and the behaviour of liquids and gases.
