Q3. Tell me about MTTR & MTBF with farmula..
Ans. 
MTTR (Mean Time to Repair) and MTBF (Mean Time Between Failures) are key metrics in maintenance engineering for reliability assessment.
• MTTR is the average time taken to repair a failed system. Formula: MTTR = Total Repair Time / Number of Repairs.

• Example: If a machine was down for 10 hours over 5 repairs, MTTR = 10 hours / 5 = 2 hours.

• MTBF is the average time between failures of a system. Formula: MTBF = Total Operatin...read more

Q2. Difference between flatness and surface roughness
Ans. 
Flatness refers to the deviation of a surface from a perfect plane, while surface roughness refers to the texture of the surface.
• Flatness is a measure of how level a surface is, while surface roughness is a measure of how bumpy or irregular the surface is.

• Flatness is typically measured using a straightedge or surface plate, while surface roughness is measured using instruments like profilometers or roughness testers.

• Fl...read more
