1) hydraulic elevator:
Hydraulic elevator systems lift a car using a hydraulic ram, a fluid-driven piston mounted inside a cylinder. You can see how this system works in the diagram below.
The cylinder is connected to a fluid-pumping system(typically, hydraulic systems like this use oil, but other incompressible fluids would also work). The hydraulic system has three parts:
- A tank (the fluid reservoir)
- A pump, powered by an electric motor
- A valve between the cylinder and the reservoir
The pump forces fluid from the tank into a pipe leading to the cylinder. When the valve is opened, the pressurized fluid will take the path of least resistance and return to the fluid reservoir. But when the valve is closed, the pressurized fluid has nowhere to go except into the cylinder. As the fluid collects in the cylinder, it pushes the piston up, lifting the elevator car.
When the car approaches the correct floor, the control system sends a signal to the electric motor to gradually shut off the pump. With the pump off, there is no more fluid flowing into the cylinder, but the fluid that is already in the cylinder cannot escape (it can't flow backward through the pump, and the valve is still closed). The piston rests on the fluid, and the car stays where it is.
2) using ice skates instead of normal shoes: the shoe distributes the force over a much larger area than the skates does. this means that the skates exerts a much higher pressure on the ice than the shoe does- this high pressure makes ice skating possible.

What is the equation for work in terms of pressure and volume?
The equation for work in terms of pressure and volume is: Work Pressure x Change in Volume.
How does the relationship between pressure, volume, and work manifest in the context of thermodynamics?
In thermodynamics, the relationship between pressure, volume, and work is described by the equation: work pressure x change in volume. This means that when pressure increases or volume decreases, work is done on the system, and when pressure decreases or volume increases, work is done by the system. This relationship helps to understand how energy is transferred and transformed in thermodynamic processes.
How does a pressure switch work in a circuit?
A pressure switch works by responding to changes in pressure levels. When the pressure reaches a preset point, the switch triggers a change in the electrical circuit, either turning on or off a connected device. It does this by physically opening or closing internal contacts within the switch.
What is the work done in an isobaric expansion?
The work done in an isobaric expansion is given by the formula: work = pressure x change in volume. This is because in an isobaric process, the pressure remains constant while the volume changes, resulting in work being done on or by the system.
How does pressure transmitter work?
A pressure transmitter works by converting a pressure measurement into an electrical signal. It typically contains a sensing element, such as a diaphragm or bourdon tube, that deforms in response to changes in pressure. The deformation is then converted into an electrical signal, usually through the use of strain gauges, which can be transmitted to a display or control system for monitoring or adjustment purposes.
Why do many celebrities start to take drugs?
Celebrities usually have lots of money, many people to do things for them, often work under substantial pressure, and may also work or socialize with others who use drugs.
All living things use energy to do what?

Which things should be in general ward in hospital for the nurse use?
A blood pressure meter and a thermometer are some of the things that should be in a general ward in hospital for the nurse to use.
Why won't an electric fuel pump work on an 1982 Camaro?
it will work but you have to use a pressure regulator in line so you can set the fuel pressure down to 6 psi. for the carburetor

Will a PS1 controller work in a PS2 console?
Yes, but not with games that use pressure sensitivity.
