Description:

Measurement experiment of Youngs modulus of solid material is a must of physics experiment in engineering universities and colleges. Through the experiment, students can master measurement method of length and micro displacement and improve experimental techniques. This apparatus is equipped with a Hall position sensor on the base of the Laboratory apparatus for measuring Youngs modulus with bending method, and it can help students to better understand and master the new measurement method of micro displacement with non-electric-quantity method. The experimental device and method of this apparatus are greatly improved comparing to old apparatus. The original experimental contents are remained and additional experimental contents is added, such as structure, principle, characteristics and operation of Hall positional sensor, which will adds to students knowledge. The apparatus has been getting favorable comments since being put into market. Its test data is stable and reliable, teaching contents are advanced and rich. The error of the apparatus in measuring Youngs modulus is 3% comparing to standard value.

EXPERIMENTS:

1. Getting familiar with characteristics of Hall positional sensor, measuring Youngs modulus of brass with bending method;

2. Calibrating Hall sensor when measuring Youngs modulus;

3. Measuring Youngs modulus of malleable cast iron with Hall sensor.
