What the uses of hydraulic press?

The idea behind the hydraulic press (machine or bench press) is that a liquid, when displaced, will exert pressure or force equally across the surface it is forced against. Because of this, hydraulic presses are commonly used for automotive and industrial repair shops, where pressing, bending, straightening, and forming is required.


How does the hydraulic system work?

A hydraulic systems works on the idea that, unlike gasses, liquids cannot be compressed. By using this idea you can set up a system that transfers pressure through liquid to aid in the lifting of an object. One great example of this at work is the breaks in your car. When you put down your foot on the breaks you exert....lets say 100N (Newton's) of force, the shaft which this force travels down would be about 4-5 cm in diameter, because the force traveling through liquid loses no energy, when the force reaches the actual pad on the wheel which has a surface area of (say) 20cm, it will exert 500N of force (force*area....5*100), which will inevitably stop the car. Initially the hydraulic system relied on water to transfer the force between the two areas, but once the true potential of this system was realized, companies set about to develop a special type of hydraulic liquid that was a poor conductor and help to reduce friction.


Did Leonardo Da Vinci know about simple machines?

His knowledge surpassed simple machines. He conceptualised a helicopter, a tank, concentrated solar power and a calculator; to name but a few. Most people today would not have the faintest idea how a helicopter works and as for solar power, electricity had not even been invented yet and Da Vinci already had ideas for it.
