Phys 2.3 - Hydraulics 0.0 / 5 ? PhysicsForces and MotionGCSEAQA Created by: DanCreated on: 04-05-13 12:41 What equations gives you pressure? P = F / A 1 of 10 What does P mean? Pressure in Nm2 or pascals 2 of 10 What does F mean? Force in N 3 of 10 What does A mean? Area in metres squared 4 of 10 What makes liquids perfect for hydraulic systems? They are incompressible and when compressed are equally distributed in all directions 5 of 10 What does this mean? This means that a force exerted at one point on a liquid will be transmitted to other points in a liquid 6 of 10 What 3 things does the force exerted by a hydraulic system depend on? Force exerted on the system, area of cylinder on which the force acts on, the area of cylinder that exerts force 7 of 10 The use of different cross sectional area's on hydraulic systems means what? That a hydraulic system can be used as a force multiplier 8 of 10 Give an example Exerting a force on a small cylinder will cause a much larger cylinder to rise. 9 of 10 How can this be used in life? A hydraulic car jack uses small amount of force to lift large objects 10 of 10
