  Universal Material Tester

  This material tester is a benchtop unit for training purposes. Simple operation and robust construction make the unit suitable for student experiments. The test spectrum for the basis unit covers tensile tests, and also Brinell hardness testing. Using the accessories that are also available, additional bending, shear, cupping and compressive tests can be performed. PC data acquisition and evaluation is also possible. The basic version of the unit does not require any additional sources of power. The test load is generated using a hand operated hydraulic system. The test load is displayed using a large gauge and a trailing pointer. The elongation of the test specimen is recorded via a mechanical gauge. The unit features a clear layout and the rapid changing of accessories.

  Experimental Set Redundant Truss

  This set for use with the universal test frame enables the distribution of forces in redundant trusses to be investigated. Due to the range of different fixed length members, numerous plane trusses can be assembled. These are made redundant by the insertion of an additional member of variable length. All members are equipped with full bridge strain gauges. The measuring amplifier is required to display the forces in the members and to further process the measured values on a PC. A set of cables to connect strain gauges and the amplifier is included. The trusses can be loaded using a spindle drive with a ring dynamometer and strain gauge.

  Cam Mechanism

  Cam mechanisms are used in many areas of technology, such as for valve control in combustion engines. The simple experimental set-up permits quick demonstration of the action principle, and can be used to demonstrate the influence of different cam shapes. The cam follower can work either as a roller tappet, cup tappet, or trailing lever. The stroke is measured using a mechanical position measurement gauge. A scaled disk indicates the associated angle of rotation.

  Shearing Force and Bending Moment Apparatus

  This demonstration unit facilitates the experimental investigation of the progression of the bending moment and shearing forces on a bar subject to point loads. In addition, the section principle commonly used in mechanics can be demonstrated. Due to the use of a low friction joint with two degrees of freedom at 1/3 of the span and two dynamometers, the measurements can be recorded directly from the bar. The deflection of the bar as result of the travel of the dynamometers and the horizontal alignment can be compensated and regulated using two adjustment bolts. The bar is loaded with graduated sets of weights that can be attached at any point on the bar.
