8.2.2. Hydraulic Actuators

Try these first

1. 1.

   What is a hydraulic actuator?

   Hint

   Focus on what type of energy they use.

2. 2.

   Name one application of hydraulic actuators.

   Hint

   Think of construction-related machinery.

3. 3.

   What is the primary function of hydraulic actuators?

   • To convert electrical energy into mechanical energy
   • To convert hydraulic energy into mechanical energy
   • To amplify sound

   Hint

   Consider what energy type they primarily use.

4. 4.

   True or False: Hydraulic actuators require more maintenance than electric actuators.

   • True
   • False

   Hint

   Think about the nature of fluid-based systems.

5. 5.

   A hydraulic actuator is designed to lift a load of 5000N. Calculate the pressure needed if the surface area of the actuator is 0.02 m².

   Hint

   Remember the fundamental physics formula relating force, pressure, and area.

6. 6.

   Design a hydraulic system for a small excavator. Detail the components you would include and how you would ensure minimal fluid leakage.

   Hint

   Think about the components and maintenance practices involved in hydraulic systems.
