Pa (pascals) OR N/m^2 2 of 12 What's the force measured in? Newtons 3 of 12 What is A? Cross sectional area (at right angles to the direction of the force) 4 of 12 Measured in? m^2 (metres squared) 5 of 12 What is virtually incompressible? Liquids 6 of 12 Where is the pressure in a liquid transmitted In all directions equally 7 of 12 Which means the force exerted at one point on a liquid will be transmitted? To other points in the liquid 8 of 12 Where is this made use of? Hydraulic systems 9 of 12 What does the force exerted by a hydraulic pressure system depend on? (1) Force exerted on the system (2) Area of the cylinder on which this force acts on (3) The area of the cylinder that exerts the force 10 of 12 What do the use of different cross-sectional areas on the effort and load sides of a hydraulic system mean it can be used as? A force multiplier 11 of 12 Which means a small effort can be used to move? A large load 12 of 12
