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

  1. Determination of the characteristic curve of the dial gauge.
  2. 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.
  3. Determination of the modulus of elasticity of steel, aluminium and brass.
