Instructions
In the experiment, the shaft and the disc are assembled and fixed on the vertical clamp of the square bracket, and three hollow pins are inserted into the small holes of the disc, and the hollow pins are distributed on both sides of the shaft as much as possible, and several are attached to the lower end of the line. For hook code, after the disc is balanced, write down the weight of the three groups of hook code, measure each arm, and calculate their torque separately. It can be proved through experiments that the equilibrium condition of an object with a fixed shaft is that the algebraic sum of moments is equal to zero.

Maintenance and precautions
1. Do not put plastic discs under heavy pressure and do not come into with organic solvents to avoid damage.
2. Lubricating oil should be added to the shaft end to prevent rust.
