Why is the fluid in the hydraulic machine liquid rather than gas?
because in its gaseous form it would be far too voluminous
What is the Difference between pneumatic cylinders and hydraulic cylinders is?
Working fluid. In one it's gas (air) and in the other it's liquid. This is a much bigger difference than it might seem at first, because gases are compressible and liquids, to a very good approximation, are not.
What is the opposite of a pulley?
There is no opposite machine to a pulley. However, a jack or hydraulic lift essentially does the reverse, lifting from below rather than from above.
What you force make things float?
Objects can be made to float by reducing their overall density so that they become less dense than the fluid they are placed in. This can be done by using materials that are less dense than the fluid, such as foam or inflatable objects. Archimedes' principle states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object, so if the object weighs less than the fluid it displaces, it will float.
If you vigorously shake a can of liquid back and forth for more than a minute will the temperature of the liquid increase?
Very slightly, yes - the kinetic motion of the fluid is parasitic - a small amount of heat is generated by friction and fluid drag and the more you shake, the more energy is added to the fluid.

Why hydraulic breaks known as hydraulic?
Because they are actuated by fluid pressure, rather than pneumatic (air) pressure.
Will it harm the hydraulic system if I use a hydraulic fluid instead of hydraulic oil?
Hydraulic fluid is hydraulic oil.... as for the type you use, depends on your system. I used to own two tractor-trailer end dumps, and I actually used ATF rather than hydraulic oil. Check with the OEM for your hydraulic system before you do this, though.
What weight Hydraulic oil for 773 bobcat skid steer?
The best thing to use is the Bobcat "orange" Hydraulic fluid. Actually you dont use hydraulic fluid in a skid loader you need to use hydrostatic transmission fluid. Drive relief pressures are in excess of 5000 psi, the fluid needs to drive the machine as well as make the lift arm raise up and down. If you cant get the Bobcat stuff than use 10w30 or better MOTOR OIL. Dumping ISO 46 or AW32 can be a very costly mistake.
Why water is only used for hydraulic testing of boiler?
because water is a liquid and simple for this test than all liquid
Why do air brake systems take more time than hydraulic brake system?
Air takes more time to flow through the lines than hydraulic fluid.
What type of hydraulic fluid goes in a 1710 ford tractor?
Go to your local parts store or fuel jobber and get a can of Tractor Fluid or your dealer and get OEM fluid. About 50 bucks a can but a lot cheaper than a hydraulic pump failure. Good Luck!
Is 4.73 fluid oz equals 4 oz liquid?
No. 4.73 fluid ounces is greater than 4 ounces. Fluid and liquid are the same thing.
Is there any liquids can replace gas in compressor?
I'm not sure what you mean but a compressor is a machine for compressing gas, it can compress all gasses. A compressor is a type of Pneumatic system. All Pneumatic systems compress air, or a gas of some kind. If you replace the gas with liquid, the system becomes Hydraulic rather than Pneumatic. Hydraulic systems require more powerfull pumps to drive them and high tensile hoses & seals through which to conduct the fluid. An air compressor is not suitable for use with liquid, as the pressures involved are generally far higher. The hydraulic equivelant of an air compressor would require a particular kind of liquid; one that is non-compressible. These liquids are manufactured specially for such systems. They are more or less the same as the brake fluid you would find in a car or other vehicle.
Why alcohol vapourises faster than liquid?
Alcohol vapourises faster than liquid because it is a volatile fluid
Can it hurt the steering pump by putting oil in it?
YES. your power steering pump is a hydraulic pump that pushes fluid through lines to make your wheels move. hydraulic fluid such as ATF or POWER STEERING FLUID is good for your power steering pump. it is a PUMP after all. OIL has the purpose of lubricating, and has very different qualities than hydraulic fluid. DO NOT put OIL in your power steering pump... put POWER STEERING FLUID or if you can't get power steering fluid AUTOMATIC TRANSMISSION FLUID will do...
A hydraulic actuator can move more precisely than a pneumatic actuator can because?
Don't quote me on this :)Hydraulic actuators work with liquids (usually oil, think hydraulic pistons in earth-moving equipment), pneumatic actuators work with a gas. By definition, a gas is compressible, a liquid is not. In physics, both gasses and liquids can be fluids.In very basic principle, an actuator works by forcing or a fluid into or removing a fluid from one end of a piston and thereby causing either pressure or a vacuum, causing the piston to move out or in, respectively. When the fluid is a gas, the gas will compress or expand a bit before it starts to move the piston and hence the actuator, introducing a lag and imprecision between when the fluid is moved and when the actuator moves. A liquid has a constant volume (it can't be compressed or expanded) and does not have this effect. hence, hydraulic actuators are more precise than pneumatic ones. :)My credibility: 1st year engineering student at UKZN, RSA.
