A flat bar is supported at two points. It is bent by the action of a force acting at its centre. The modulus of elasticity is determined from the bending and the geometric data of the bar.
Benefits
Find out the parameters that give a bar stability
Measure the difference of elasticity in various metals with different lengths
Learn how to determine forces with a dial gauge
Tasks
Determination of the characteristic curve of the dial gauge.
Determination of the bending of flatbars as a function of the force; at constant force: of the thickness, of the width and of the distance between the support points.
Determination of the modulus of elasticity of steel, aluminium and brass.
