The experimental steps of measuring Young's modulus by tensile method are as follows: (1) After starting the experiment, click and drag the instrument from the experimental instrument bar to the experimental platform. (2) Telescope adjustment. Double-click the small icon of the telescope on the desktop to pop up the adjustment form of the telescope. You can click the focus knob to adjust the clarity of the ruler, and click the eyepiece knob to adjust the clarity of the reticle.

Click the unlock button left and right to adjust the locking state. Click the "Start Measurement" button to pop up the schematic diagram of the measured object, drag the steel wire into the screw micrometer, unlock it, and turn the handle to measure the diameter of the steel wire.

(4) optical lever. Double-click the flat mirror part of the small icon of the optical lever on the desktop to pop up the flat mirror adjustment form of the optical lever, and click the flat mirror to adjust the angle of the flat mirror.

Double-click the base part of the small icon of the light lever on the desktop to pop up the base adjustment form of the light lever, click the base knob to adjust the horizontal state of the base, and observe that the small bubble of the horizontal bubble meter is in the center, indicating that the base is horizontal, otherwise it needs to be adjusted continuously.

(5) Instrument calibration adjustment. Double-click the meter ruler icon on the desktop to pop up the meter ruler adjustment form. Click the button "Measure the length of steel wire" to pop up an enlarged view of measuring the length of steel wire. Drag the white area to read the enlarged instrument scale on the right.
