Combined Bending And Torsion uses specially machined necked specimens which are clamped at one end to the base plate and at the other end to a counterbalanced circular loading plate. Regular interval graduations on the loading plate allow a special hanger to locate. The object of this experiment is to determine what levels of Combined Bending And Torsion cause elastic failure in different materials, and to compare them with various theories of failure. The specimen deflection is measured by a dial gauge mounted diametrically opposite the load point. A set of calibrated weights is supplied along with a set of test specimens. Further test specimens are available separately. The special hanger enables pure bending, pure torque or a combination of both to be applied depending on the position of the hanger.
Experimental Capabilities:
To compare the results with the established theories of failure.
To determine elastic failure of a specimen subjected to several ratios of bending and torsion simultaneously.

The pendulum body oscillates in a plane purely translationally without rotation. In a bifilar suspension, the pendulum body is suspended over two threads. In a trifilar suspension with three threads, the pendulum body is set in a torsional vibration. This kind of pendulum can be considered as a mathematical pendulum. The torsional vibration can be used to determine the moment of inertia by experiment.
Features:
Moment of inertia in an experiment on a rotary pendulum.
Ideal mathematical pendulum can be demonstrated.
Learning Objectives And Experiments:
Determine the mass moment of inertia
Influence of thread length on the oscillation period.
Diagram in the front panel with similar distribution to the elements in the real unit.
Quick connections for adaptation to feed hydraulics source.
Stainless structure.

The programmable controller is one of the most important developments in industrial automation because of its ability to be quickly programmed to control a wide range of industrial processes and machines. Computer Control Learning System covers how to program, operate, and interface programmable controllers in a variety of industrial applications used in the automotive, packaging, and technological assembly industries, to name a few. Typical applications include: robots, conveyors, electric motor controls, air conditioning, process control, plastic injection molding, and CNC machines. The Computer Control Learning System PLC I/O terminals are wired to heavy duty banana jacks, enabling learners to quickly connect the PLC I/O to the I/O devices. Computer Control Learning System also includes communication cable, student curriculum or interactive multimedia, and a student reference guide, and requires PLC programming software. The Computer Control Learning System includes a metal, silkscreened enclosure mounted with an industrial 1000 programmable controller. The enclosure mounts to the Electric Relay Control Learning System to provide control of real-world electrical and pneumatic application devices.

The Freeze Drier comprises a cylindrical working chamber 300mm diameter by 370mm deep mounted adjacent to a 210mm diameter condenser chamber in a painted stainless steel cabinet. All controls are via a touch screen display with real-time plotting of temperatures and vacuum level. Drying rate may be controlled by the application of heat to the working chamber via a heating element with temperature controller. Both chambers incorporate a clear acrylic lid on an O ring seal. Products to be freeze dried may be frozen in the working chamber prior to drying. The chamber is defrosted by an electrical heater and the ice plug may be removed whole via the lid or allowed to melt totally and drained through the drain plug. Ice build up in the condenser chamber can be observed through the acrylic lid.

The cooling is obtained by giving heat to the exterior in the zone around the compressor. The cooled fluid expands in the expansion valve and in the evaporator and is transformed in gas. The compressor activated by the engine compresses the refrigerant which consequently warms up; in the condenser the working fluid is cooled until it reaches the liquid phase. To cool the external air refrigerating compressor based systems are exclusively used. The heat necessary for such transformation is subtracted from the entering cool air.
The simulator analyzes all the phases of the refrigeration cycle. In particular:
Relations between temperature and pressure in the refrigerant
Pressure switches
Temperature regulation
Operation of the compressor
Operation of the condenser.
The practice kit provides the material necessary for students to systematically learn how components can be joined together in a professional way using pins. Both flat and cylindrical parts are pinned together. We recommend that the exercises are carried out in a workshop, as all preparations such as scribing, drilling, clamping, reaming and joining must be carried out in a correct and proper manner by the student. The material is clearly laid out on a plastic tray. The well-structured instructional material outlines all the necessary technical information and provides a step-by-step guide through the exercises.
