An auger is a type of drill; a hydraulic auger is a drill that uses hydraulic pressure for power. It can be a relatively small and light hand tool or a large piece of construction equipment. The hydraulic auger was first introduced in 1953 as a hydraulic drill rig. Since then, the ...
The Working Principle and Building Blocks A PID controller’s objective is to produce a control signal that can dynamically reduce the difference between the output and the desired setpoint of a given system. Consider the exemplary scheme displayed in Figure 1. As an initial step, the output of...

Pascal's Principle is applied when a change in pressure forced on an enclosed liquid is transmitted to all of the fluid and the walls of the container it is in. Learn how this concept has many applications in everyday life and look at example calculations of this principle. Relat...
What's the McLaren MP4-12C like to drive? As you'd expect from McLaren, the 12C is extremely high-tech. It has a one-piece carbon-fibre chassis that manages to be both strong and light, while the revolutionary suspension uses adaptive dampers and complex hydraulics to provide control rather...
Thermal time could be used in principle in all of the equations from Table 3. In fact, its use is often restricted to crop models, both to set up the crop developmental program but also to parameterise the Monteith equation (Box 2) using °C d instead of d. While there is no ...
The simple key to the power of our upper classes is this: that they have always kept carefully on the side of what is called Progress. They have always been up to date, and this comes quite easy to an aristocracy. For the aristocracy are the supreme instances of that frame of mind of...
The first and most obvious impact is the degradation and productivity loss of fertile soils. Population growth goes hand in hand with a growth in food demand. The removal of the natural vegetation, deforestation, and the intensification of crop cultivation have increased the vulnerability of soil ...
In automobiles like cars and trucks, the starter solenoid is part of an automobile starting system. Commonly referred to as the "starter relay," it receives a large electric current from the car battery and a smaller electric current from the ignition switch. When the key is turned to start...
