3 cards from this section. Quick, good the night before a test.
What is a hydraulic actuator?
Think about how it can lift heavy things.
Name one advantage of hydraulic actuators.
Consider where you would see very heavy lifting.
What principle do hydraulic actuators operate on?
Consider how pressure behaves in liquids.
True or False: Hydraulic actuators are less effective than electric actuators in lifting heavy loads.
Compare the capabilities of both types of actuators.
A construction site needs to lift a 20,000 N load using a hydraulic actuator. If the actuator's cylinder has a radius of 0.1 m, what pressure is needed?
Remember to calculate the area first using the radius.
Explain the potential environmental impacts of hydraulic systems if leaks occur in an outdoor construction scenario.
Consider what happens if polluted fluids enter the ecosystem.
