Using this accessory for the universal material teste a bending bar is investigated. An I-section steel beam is used as the base. This is straightforwardly bolted to the lower cross-member on the. This is mounted on two supports and loaded with a point force generated by the tester. By sliding the bearing it is possible to apply the force in different positions and change the support width. The influence of the modulus of elasticity and planar moment of inertia is also demonstrated. Using the apparatus, the relationship between load and elastic deformation can be demonstrated.

Wound Rotor Motor Learning System covers the function, operation, and performance characteristics of wound rotor motors. The Wound Rotor Motor Learning System requires the Basic Electric Machines Learning System and the DC Generators Learning System for use. While VFDs and standard induction motors have replaced wound rotor motors in many applications, these motors are still used for heavy-duty, high torque applications such as industrial cranes and hoists.
The Wound Rotor Motor Learning System includes a wound rotor speed controller, a wound rotor motor, banana leads, in-depth curriculum, an installation guide, and a student reference guide. Learning systems feature real-world, industrial-grade components for both durability and to facilitate learners in gaining hands-on practice with actual equipment that they'll find in the field. These components will be used to study topics such as wound rotor speed control, performance characteristics, and motor reversing.

The forces that act on the lathe tool during machining are measured in three directions: cutting force, feed force and passive force. The 3-component force measurement device uses a strain gauge system. Investigation of cutting forces during turning is fundamental to the teaching of cutting techniques. The set-up comprises a transducer, which also holds the lathe tool, and an amplifier unit with digital displays. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. The amplifier unit supplies the strain gauge bridges and displays the measured values on three digital displays. The experiments must be conducted in a workshop environment, as a suitable lathe is required.

The lower value (diastole) corresponds to the pressure that we have in the arteries between two heart beats. The upper value (systole) is the maximum pressure that is recorded in the artery in consequence of the heartbeat. In blood vessels there must be a certain pressure in order that the blood can properly flow. Each heartbeat causes a pressure wave that is transferred to the arteries. Therefore, it is necessary to properly evaluate the pressure and its variability through a pressure and heart beat digital meter.
