Hydraulic
| Question | Answer |
|---|---|
| What is pressure? | A Measure of the amount of force that acts on a unit of area. |
| What is one major mechanical advantage of a Hydraulic system? | Ease with which force can be transmitted over large distances and into sealed compartment or Large gain in mechanical advantage made possible by varying the size of pistons. |
| What are three characteristics of Hydraulic fluid? | Viscosity, Chemical Stability, Flash Point, Fire Point |
| what's the relationship Between Area, Distance, And Volume? | The area of the piston, the distance it moves, and the volume of the fluid displaced Volume = Area x Distance |
| Types of hydraulic fluids: | Vegetable-base Mineral-base Synthetic Fluid |
| what' re characteristics that most desirable for hydraulic fluids? | -high flash point and high fire point. |
| what stores fluid under pressure and provides instant pressure to other components? | hydraulic accumulators |
| flash point is described as: | ignites momentarily |
| fir point is described as: | ignites, continues to burn. |
| What is the relationship between pressure, force and area? | Pressure = Force x Area |
| What is one of the requirements of hydraulic fluid? | Fluid must be incompressible |
| What things must hydraulic fluid be? | Must not foam Not compressible Not corrosive Viscus Lubricant |
| What is flashpoint? | Where a liquid is heated to where flammable vapor is formed |
| What is fire point? | When the vaporized gas catches |
| What are the three kinds of hydraulic fluids? | Vegetable, mineral, synthetic |
