Detailed Mechanical Animation Explanation, Solving Mechanical Principles I Have Longed to Understand – Do You Know?
How does a treadmill ensure a person doesn't fall over?
Rotation▼
There are 6 rubber vibration dampers attached to the bottom position, acting as shock absorbers, reducing the vibration caused by the belt▼
The board has a thickness of 2.5 cm, with a wax coating on the outside and a hinge at the back, providing a stable surface for the running board, reducing the impact on the knee joint▼
The rollers need to be robust, ensuring that each runner's foot can accurately record their stride frequency. Through the computer console, the expected speed can be set, and each foot is heavily placed on the board, and the driver immediately cancels the deceleration effect when the belt begins to slow down▼
The electronic controller detects changes in speed and then sends a command to the engine to accelerate, allowing the belt to return to the preset speed, matching the runner's stride, so that the runner feels relaxed and comfortable throughout the run▼
2. How do the latest technologies assist in 'tuning' a vinyl record?
The turntable contains 240 precision parts working together▼
Two interlocking zinc alloy platter, perfectly maintain stability, the needle accurately reads the record▼
Carbon-made needles control the reading of the subtle rise and fall, transforming the protrusions and indentations on the record into music▼
The needle is fixed at the end of the arm, and when the needle moves forward and backward, the coil rotates between the two magnets, generating current, which drives the amplifier and speaker to produce classic and beautiful sound▼
7. How does a Yo-Yo ball spin like a Formula 1 engine?
Balance design allows the Yo-Yo ball to be thrown out and returned smoothly, while also maintaining a long-lasting rotation and speed that does not slow down▼
In order to achieve this, the Yo-Yo ball has a device slightly smaller than a penny inside▼
Between the inner and outer circles, there are 10 small steel balls rolling together to block the friction between the inner and outer circles▼
Although the rope is wrapped around the outer circle, the inner circle can still rotate at full speed, with the same speed as a Formula 1 car▼
This ingenious separation method allows the Yo-Yo ball to continue spinning until the end, while the weight on both sides of the Yo-Yo ball also helps to extend its deceleration time▼
8. How do vending machines ensure you get your food?
In the back of the vending machine's eye, there is a miniature computer controlling the corresponding 132 small firebox-sized motors▼
These motors can drive the rotating wheel to rotate 360 degrees▼
When food falls, it will pass through 10 infrared light beams, if no object is detected, the computer will issue a command to return the coins▼
