Hydraulic Engine: Ball Spin, Stop & Why?

In summary, the conversation discussed the possibility of a metal ball spinning in the picture shown, with one person mentioning the potential for air pressing through a valve and causing the ball to spin. However, another person pointed out that if the ball, air, and oil are initially stationary, the ball will not suddenly start to spin, and it would stop spinning when viscous drag forces stop it. The conversation also mentioned the forum rules prohibiting discussion of perpetual motion machines.

What will happen with metal ball in the below picture? it will spin? if yes, when it will stop and why? I am not very faimiliar with physics, but I am sure that ball must spin :D

If the ball, air, and oil are all initially stationary then it will not suddenly start to spin.

Please be aware of the forum rules prohibiting discussion of perpetual motion machines.

air will be pressed through valve

Then it could start spinning. It would stop spinning when viscous drag forces stop it.

The container appears sealed at the bottom so the pressure in the oil is likely to be the same/similar to that of the air - so why would the air go past the ball?
 

1. How does the hydraulic engine work?

The hydraulic engine works by using pressurized fluid to transfer energy and power to various mechanical components. In the case of a ball spin and stop mechanism, the pressurized fluid is used to rotate a cylinder which then causes a ball to spin and stop.

2. What is the purpose of the ball spin and stop mechanism in a hydraulic engine?

The ball spin and stop mechanism is often used in hydraulic engines to regulate the flow of fluid and control the speed of the engine. It can also be used for precise stopping and starting of the engine.

3. What causes the ball to spin and stop in a hydraulic engine?

The rotation of the cylinder in the hydraulic engine creates centrifugal force which causes the ball to spin. When the pressurized fluid is released, the cylinder stops rotating and the ball is no longer affected by the force, causing it to stop.

4. Why is a hydraulic engine preferred over other types of engines?

Hydraulic engines are often preferred for their high power-to-weight ratio, as well as their ability to operate at high speeds and handle heavy loads. They also have fewer moving parts, making them more reliable and easier to maintain.

5. How is the spin and stop speed of a hydraulic engine controlled?

The speed of the spin and stop mechanism can be controlled by adjusting the flow of the pressurized fluid. By increasing or decreasing the flow, the rotation speed of the cylinder and the spin and stop speed of the ball can be adjusted accordingly.
