Deformation of Straight Beam Model MT 011

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 Sci-tech Deformation of Straight Beam Apparatus Model MT 011 can be supported in different ways.
