Open loop and closed loop are two modes of operation in hydraulic systems.

• Open loop operation: The hydraulic system operates without feedback control. The output is not adjusted based on the system's performance.

• Closed loop operation: The hydraulic system uses feedback control to adjust the output based on the system's performance.

• Open loop systems are simpler and less expensive, but they lack precision and accuracy.

• Cl...read more

The starting circuit is responsible for initiating the engine's operation.

• The starting circuit consists of components such as the battery, starter motor, ignition switch, and solenoid.

• When the ignition switch is turned on, it sends a signal to the solenoid, which then engages the starter motor.

• The starter motor uses electrical energy from the battery to turn the engine's crankshaft, starting the combustion process.

• Once...read more
