PSI stands for Pounds per Square Inch, a unit of pressure measurement commonly used in engineering and physics.

• PSI is used to measure pressure in various systems, such as in pneumatic tools, hydraulic systems, and air compressors.

• 1 PSI is equal to 0.068046 atmospheres or 6,894.76 Pascals.

• For example, a car tire may require inflation to 32 PSI for optimal performance.

Firing strokes position refers to the position of the firing strokes in an engine.

• Firing strokes position is crucial for the proper functioning of the engine.

• The firing order of the engine determines the position of the firing strokes.

• Incorrect firing strokes position can lead to engine misfires or damage.

• Common firing orders include 1-3-4-2 for a 4-cylinder engine and 1-8-4-3-6-5-7-2 for a V8 engine.

To work a hydraulic pump, you need to understand its components and operation.

• Understand the basic components of a hydraulic pump such as the inlet, outlet, and pistons.

• Ensure the pump is properly connected to a power source and the hydraulic system.

• Monitor the pump's pressure and flow rate to ensure optimal performance.

• Regularly check and maintain the pump to prevent any malfunctions or breakdowns.

• Examples: Gear pump,

A torque gun is a tool used to apply torque to fasteners such as nuts and bolts.

• Ensure the torque gun is set to the correct torque value for the fastener being tightened.

• Hold the torque gun perpendicular to the fastener and apply pressure while pulling the trigger.

• Listen for the click or beep indicating the desired torque has been reached.

• Do not over-tighten the fastener as it can cause damage.

• Regularly calibrate and m

Coalesce is a function used to return the first non-null value in a list of expressions.

• Coalesce function is commonly used in SQL to handle null values.

• It takes multiple arguments and returns the first non-null value.

• Example: COALESCE(column1, column2, 'default') will return the value of column1 if not null, else column2, and if both are null, it will return 'default'.

Repartition is the process of redistributing data across partitions in a distributed system.

• Repartitioning helps in balancing the workload and improving performance in distributed computing environments.

• It involves moving data between partitions based on certain criteria such as key values or hash functions.

• Repartitioning can be done in Spark using operations like repartition() or coalesce().

A non repeatable character is a character that appears only once in a given string.

• Iterate through the string and count the frequency of each character

• Identify the characters that have a frequency of 1

• Return the first non repeatable character found
