Q2. Explain on flushing & cavitation
Ans. 
Flushing is the process of cleaning out a system by forcing fluid through it, while cavitation is the formation of vapor bubbles in a liquid due to rapid changes in pressure.
• Flushing involves using a fluid to remove contaminants or debris from a system, such as a hydraulic system or a pipeline.

• Cavitation occurs when the pressure in a liquid drops below its vapor pressure, causing bubbles to form and collapse, leading t...read more

Q3. Explain on different materials & their grades
Ans. 
Materials come in different grades based on their composition, properties, and intended use.
• Materials can be classified into metals, polymers, ceramics, and composites.

• Each material type has different grades based on factors like strength, durability, conductivity, and corrosion resistance.

• Examples include steel grades like 304, 316, and 430, polymer grades like HDPE and PVC, and ceramic grades like alumina and zirconi

Q4. Stress vs strain on mild steel & different materials
Ans. 
Stress is the force applied to a material, while strain is the resulting deformation. Mild steel has a linear stress-strain curve.
• Stress is the force applied to a material per unit area, measured in N/m^2 or Pascals.

• Strain is the resulting deformation of the material, measured as a ratio of the change in length to the original length.

• Mild steel typically has a linear stress-strain curve until it reaches its yield point...read more
