Study of Bending Stress In A Beam
Converting strains to stresses
Strain gauges
Second moment of area
The bending equation
The neutral axis.
An inverted aluminium T-beam is mounted between two simple supports on knife edges. The load onto the T-beam is applied using a fine screw jack mechanism with integral load cell. A standalone experiment for determining the bending stresses and strains across the surface of a T-beam. The load cell arrangement and supports create a three (3) point loading.
These strain gauges are paired with temperature compensation dummy gauges for output stability. A number of precision strain gauges are arranged on the T-beam specimen. Each strain gauge pair is numbered for accurate connection to the Interface.
