What is hydraulics?
Hydraulics is a mechanical function that operates by introducing pressure to a liquid.
Hydraulics systems use liquid (oil) to produce mechanical movement, typically through hydraulic cylinders to move pistons.
How do hydraulic systems produce mechanical movement?
By pumping liquid (oil) through hydraulic cylinders to move pistons.
This process allows for the control of mechanical movement through pressure applied to the liquid.
What is the primary function of gears?
Gears are a toothed wheel that works with another wheel to change the speed of a driving mechanism.
Gears are commonly used in applications like vehicles to adjust the speed of driven parts.
What is the primary function of pulleys?
Pulleys are a wheel with a grooved rim that allows a rope to pass through, changing the direction of a force applied to the rope.
Pulleys are used to lift heavy weights efficiently.
