Get Technology Grade 9 Term 2 Notes

Pushing plunger A causes plunger B to move out and pushing plunger B in causes plunger A to move out. This works even if the syringes are not in the same plane. i.e. if the tubing is bent by 90° as long as there is no kink in the tube that prevents the free flow of fluid.

So, Technology is about designing solutions to technological challenges by using knowledge and understanding in ways that are ethical and in a manner that benefits human beings without having a negative impact on the environment.

Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

Pascal's principle When we apply pressure anywhere to a fluid in a closed container, the force is transmitted equally in all directions. This happens throughout the fluid and onto the walls of the container.

Examples of Pascal's principle applications include hydraulic crane, hydraulic lift, hydraulic jack, and hydraulic brake system. An excavator digging a hole, a car being lifted by a hydraulic lift, and even squeezing a toothpaste tube applies Pascal's principle.

Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and the walls of the container. The pressure at any point in the fluid is equal in all directions.

Two syringes that are connected with a tube can be called a syringe system. If the tube and syringes are filled with air, it is called a pneumatic system.
