Apparatus for Measuring Young’s Modulus

Description Measuring apparatus for investigating the elastic deformation of rods of flat geome-try and for determining the modulus of elasticity. Features a strain gauge unit for determining the deformation of electrically conducting material samples. The strain gauge unit is electrically connected to the material sample in such a way that placing of the probes on the sample is determined with a high degree of sensi-tivity and displayed with the help of two LEDs. The bending of the material sample with the weight suspended is measured to an accuracy of 0.01 mm and the modulus of elasticity can then be calculated from the reading.

Battery for strain gauge unit: 9 V, 6F22
Dimensions: 550 x 280 x 500 mm3
Weight: 5.5 kg approx.

Contents:
6 Flat steel rods (w: 15 mm, l: 200 / 300 / 400 mm, thickness: 2 / 3 mm)
1 Strain gauge unit
1 Horizontal beam with stand
2 Knife-edge bearings
1 Clamping chuck
