Who will be expressed in square inches what is pressure force applied to a unit area. A resistance to flow and is normally expressed in pounds per square inch what is resistance any force which stops or retards the movement of a body. resistance to the movement of a solid could be such as fiction or inertia what is psig gauge pressure. the pressure reading does not take into account atmospheric pressure what is psia absolute pressure. pressure that is equal to the gauge pressure plus atmospheric pressure what is energy the ability or capacity to do work what are the 2 forms of energy potential energy which is referred to as stored energy, which is present in a hydraulic system in the form of pressure. kinetic energy referred to as energy in motion, which is a present in a hydraulic system in the form of flow What type of valve is the simplest got a directional control valve Check valve How should a gravity valve be mounted Horizontally what kind of valve is used to maintain control over a vertical cylinder so that it will not fall freely because of gravity counterbalance valve what kind of valve is used to prevent or control a motor with a load from running away. It is directly and remotely operated at the same time, but not at the same place in the valves brake valve how will you ever be able to tell if the system has a problem if you don't know how the system is supposed to work find out as much as possible about the malfunction, never disassemble any component unless you are sure that it is at fault what is the number 1 enemy of hydraulic systems dirt or contaminants what should you always do before adding hydraulic fluid to the system filter it what are the 3 major groups to help simplify the troubleshooting process energy group, mechanical group, fluid group AuthorAnonymous ID156504 Card SetSS Hydraulics.txt DescriptionSS Hydraulics.txt Updated2012-05-30T21:07:02Z Show Answers
