The conversation between human and AI assistant.
Why are hydraulic systems used in machinery like bulldozers & backhoes, while pneumatic systems are used for things as opening and closing bus doors?
That makes sense. Are there any other notable differences between hydraulic and pneumatic systems?
Yes, one key difference is that hydraulic systems use liquid to transmit force, while pneumatic systems use gas. Additionally, hydraulic systems tend to be more reliable and have a longer lifespan, but are also more expensive to install and maintain than pneumatic systems.
