Principle

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.

Learning objectives

Young's modulus
Modulus of elasticity
Stress
Deformation
Poisson's ratio
Hooke's law
