How will the work done on the input piston compare to the work done by the output piston in a hydraulic device?
The work done is equal
Why the piston of gauge pressure rotating until its freely suspend?
The piston of a gauge pressure rotating until its freely suspend because the weight of the piston is balanced by the centrifugal force. The centrifugal force is created by the rotation of the piston and is equal to the weight of the piston.
When does output force equal input force?
Output force can only equal input force in a system where there are no losses. In the "real world" we live in, there are losses in every system, and that means that output force can nerver equal input force.
What is the basic principle of hydraulic press?
The basic principle of a hydraulic press is that the hydraulic oil pressure remains constant in an enclosed system, where, the area on which it acts, will generate a force equal to the area multiplied by the pressure (where, pressure is equal to force per unit area). This is well defined as per pascal's law, for which, pl refer wikiepedia.
If the work on a machine equal the output work the machine is said to be 100 percent effentient?
Yes.
How will the work done on the input piston compare to the work done by the output piston in a hydraulic device?
The work done is equal
What does the actuator do?
The most common actuator is a hydraulic actuator or an electro-servo actuator. These are linear actuators that move a piston rod to a set stroke and force. It is used to push and pull at a fixed length(stroke) and force. Used in conjuction with rods and cranks, the actuator can be used to move controls through variable geometry such as arcs. The Hydraulic Actuator has a piston internal to the housing. The hydraulic pressure is ported on one end and forces the piston to move to the opposite end, which pushes the rod to extend it. Reversing the hydraulic pressure(or applying it at the other side of the piston) will cause the rod to stroke back to original position. The force that is available is equal to the hydraulic pressure times the area of the piston.
How does a hyraulic lift work?
Pascal's principle : Pressure applied to an enclosed fluid is transmitted undiminished to every part of the fluid, as well as to the walls of the container. A common application of this is a hydraulic lift used to raise a car off the ground so it can be repaired at a garage. A small force applied to a small-area piston is transformed to a large force at a large-area piston. If a car sits on top of the large piston, it can be lifted by applying a relatively small force to the smaller piston, the ratio of the forces being equal to the ratio of the areas of the pistons.
How do car hydraulics work?
Force is equal to pressure times area. By increasing the area of the output force, the force goes way up. This is because water cannot be compressed, and therefore the pressure cannot change. In this way, a hydraulic device works almost like a lever. It increases the area of the output force and therefore decreases the amount of input force needed.

Whose principle applies to hydraulic machines?
Pascal's Law, framed by Blaise Pascal, states that "Pressure applied to any part of a confined fluid transmits to every other part with no loss. The pressure acts with equal force on all equal areas of the confining walls and perpendicular to the walls." This is the basic principle for any hydraulic system.
Why the piston of gauge pressure rotating until its freely suspend?
The piston of a gauge pressure rotating until its freely suspend because the weight of the piston is balanced by the centrifugal force. The centrifugal force is created by the rotation of the piston and is equal to the weight of the piston.
Why an economy's income must be equal to its output?
Because output generates income.
How does a hydraulic flow divider work?
A rotary flow divider is essentially two hydraulic gear motors of equal displacement that are mechanically linked (the output shafts are coupled together). When fed from a single line, they must both turn at the same speed because they are linked and becasue they have equal displacement they therefore use the same amount of oil, hence evenly dividing the input oul between the two motors.
When does output force equal input force?
Output force can only equal input force in a system where there are no losses. In the "real world" we live in, there are losses in every system, and that means that output force can nerver equal input force.
Are all horse power output equal to exactly 1 horse power?
The output of a machine depends on the manufacturer's testing variables. Horse power output is usually roughly equal to one horsepower.
What is equilibrium GDP?
In the short run, equilibrium GDP is the level of output at which output and aggregate expenditure are equal
