Perto Junior Software Engineer Interview Questions and Answers

Pneumatic systems use compressed air to transmit power for various applications.

• Compressed air is stored in a tank and released through valves to actuate cylinders or motors.

• Pneumatic systems are commonly used in industries for automation, such as in manufacturing processes.

• Examples include pneumatic drills, robotic arms, and air brakes in vehicles.

Sensors are devices that detect and respond to physical input from the environment.

• Temperature sensors - detect changes in temperature

• Pressure sensors - measure pressure changes

• Motion sensors - detect movement

• Proximity sensors - detect nearby objects

• Light sensors - measure light intensity

MTTR stands for Mean Time To Repair, the average time taken to repair a failed component. MTBF stands for Mean Time Between Failures, the average time between failures of a component.

• MTTR is the average time taken to repair a failed component.

• MTBF is the average time between failures of a component.

• MTTR = Total downtime / Number of failures

• MTBF = Total uptime / Number of failures

Power factor is a measure of how effectively electrical power is being used in a circuit.

• Power factor is the ratio of real power to apparent power in an electrical system.

• It is important for efficient power transmission and distribution.

• Power factor is maintained by using power factor correction devices like capacitors.

• A power factor of 1 indicates all power is being used effectively, while a lower power factor means s...read more
