Virtual Work Principles Apparatus Model MT 103
Sci-tech Virtual Work Principles Apparatus Model MT 103 is used for applying the principle of virtual work to the derivation of redundant reactions. It is to be used with Universal Structural Frame. An elastic beam is supported at both ends by moment supports. Both supports permit the application and measurement of moments and rotations. A third support, vertical force support, is used for the case of two span continuous beam. A clamp on moment application device with a mean to counter balance the device weight is provided to apply a pure moment and measure rotation. The beam is loaded by weights. The deflection and slope of the beam can be measured by dial indicators.
Size: | 120cm x 50cm x 110cm (LxWxH) |
Weight: | 15 kg |
Item Description
Features
- comparison of different methods to determine the elastic line: virtual work, Mohr’s analogy
- statically determinate and indeterminate systems
- various load cases: point load or bending moment
Beams are key structural elements in mechanical engineering and in construction which are subject to deformation under load. In the case of a simple beam this deformation can be predicted by various methods, such as the principle of virtual work.
The beam under investigation in MT 103 can be supported by different bearing methods. Two supports with clamp fixings and an articulated supports with a force gauge are provided to realize statically determinate or indeterminate systems. The two supports with clamp fixings are provided with dial gauges and can also be used as articulated supports. These dial gauges enable the angle of inclination of the beam to be determined at the support. A third dial gauge records the deflection of the beam at a random point.
A device is additionally provided to generate a bending moment at a random point on the beam. A fourth dial gauge records the angle of inclination of the device.
The beam is placed under load by weights (point load and coupled forces to generate the bending moment). The clamping moment on the supports can be determined by means of weights.
The various elements of the experiment are clearly laid-out and housed securely in a storage system. The complete experimental setup is arranged in the frame MT 027.
