Good Day! 10/7/2015 How is it that you can stop a huge car by just pushing on a pedal? It seems like you would need more force than that doesn’t it? The answer will come before the class ends.

Before we get to the Hydraulics We need to finish the question from that we started yesterday. We will do this with the worksheet Archimedes. Archimedes

Transmitting Pressure in a Fluid When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.

Hydraulic Devices In a hydraulic device, a force applied to one piston increases the fluid pressure equally throughout the fluid.

Hydraulic Devices By changing the size of the pistons, the force can be multiplied.

Hydraulic Systems Activity Click the Active Art button to open a browser window and access Active Art about hydraulic systems.

Comparing Hydraulic Lifts In the hydraulic device in Figure 15, a force applied to the piston on the left produces a lifting force in the piston on the right. The graph shows the relationship between the applied force and the lifting force for two hydraulic lifts.

Comparing Hydraulic Lifts –Lift A: 4,000 N; lift B: 2,000 N Reading Graphs: –Suppose a force of 1,000 N is applied to both lifts. Use the graph to determine the lifting force of each lift.

Comparing Hydraulic Lifts –3,000 N Reading Graphs: –For Lift A, how much force must be applied to lift a 12,000-N object?

Comparing Hydraulic Lifts –Lift A, because it multiplies force more than lift B. Drawing Conclusions: –Which lift would you choose if you wanted to produce the greater lifting force?

Comparing Hydraulic Lifts –Lift A: applied force is multiplied by four; lift B: applied force is multiplied by two. Interpreting Data: –By how much is the applied force multiplied for each lift?

Hydraulic Brakes The hydraulic brake system of a car multiplies the force exerted on the brake pedal.

How is pressure transmitted in a fluid? Pressure is transmitted equally to all parts of the fluid. What is a hydraulic system? A hydraulic system uses a confined fluid to transmit pressure. Question Answer A Few things to think about
