Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.
Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
In this interactive object, learners assess an accident victim's changing condition and suggest actions that the nurse would take in response to vital signs and lab results regarding the function of Ms. Cindy's kidneys.
Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.
