deformation of a beam on two or more supports under point loads (e.g., single-span beam)
- Beams are key structural elements in mechanical engineering and in construction.
- A beam is a bar-shaped component in which the dimensions of the cross-section are much smaller than the length and which is subjected to load along and perpendicular to its longitudinal axis.
- The load perpendicular to the longitudinal axis causes a deformation of the beam – that is, bending.
- Based on its size, the beam is viewed as a one-dimensional model.
- The science of the strength of materials deals with stress and strain resulting from the application of load to a component.
- Many fundamental principles of the strength of materials can be illustrated well by a straight beam.
- The beam under investigation in WP 950can be supported in different ways.
- This produces statically determinate and indeterminate systems which are placed under load by different weights.
- The load application points are movable.
- Three dial gauges record the resulting deformation.
- Three articulated supports with integral force gauges indicate the support reactions directly.
- The articulated supports are height-adjustable, so as to compensate for the influence of the dead-weight of the beam under investigation.
- A fourth support clamps the beam in place.
- Five beams of different thicknesses and made of different materials demonstrate the influence of the geometry and of the modulus of elasticity on the deformation of the beam under load.
- 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.
