2. Adjust the four outer rings of the gyroscope to the same plane. After the motor speed is normal, put the rotor of the gyroscope on the wheel of the motor. Driven by the motor, the rotor can rotate at high speed (hold the handle and four outer rings of the gyroscope tightly, and pay attention to the direction of rotor rotation consistent with the direction of the marked arrow). After the rotor rotates at high speed, release the pedal switch to demonstrate the rotation phenomenon. At this time, you can hold it in your hand and change the direction of the outer ring. When you see that the rotor direction is unchanged, insert the base after the experiment.
3. Insert the turntable into the base for use, and drive the gyro to rotate at high speed (clench fists with both hands, and the rotation direction is the same as the marked direction). Put one end of the gyro with a crossbar on the turntable, and when you see the gyro rotating at high speed, the turntable will also rotate at the same time. After the gyro slows down obviously, it should be taken away quickly to avoid the gyro falling and rolling and hurting people or rolling away.
4. Put the high-speed rotating gyro on the socket to demonstrate the phenomenon of rotation and precession.
5. Put the high-speed rotating gyro on the track to demonstrate the descent and precession of the gyro.

Civil engineering safety management
Safety is the most important part in building construction. First, life is above everything else. No one may arbitrarily deprive a person of his life except as prescribed by law. Therefore, to ensure safety in construction, the responsibility of safety is more important than Mount Tai. Safety and benefit are linked, and only when there is safety can there be benefits.
Safety work should always be unremitting, every day, all the time. For those who violate safety regulations, we should not only educate and punish them, but also be polite when giving opportunities and not breed laziness. The safety concept of construction work of building engineering is the benefit concept of building engineering. Whoever has mastered this level will have a chance.
