Why is it important to maintain mechanical systems

3 points that are detailed please.

Thank you very much indeed!

Firstly, the obvious - wear and tear. Say if you have three cogs which turn by one cog (the main cog). The main cog will eventually wear out and will lessen the productivity of the the seccond and third cog.

Seccondly - oil. The cogs will require lubricant in order to stay cool and to be able to turn efficently. The oil eventually runs dry and the mechanical system would heat up or not work as efficently.

Thirdly - internal componants. What makes the main cog turn? other cogs. These cogs will require even more attention as they would be smaller and harder to repair if damaged.

Safety - depending on mechanical systems, but roller coaster theme parks and jet airliners have to have regular maintenance and daily inspections because a fault in a mechanical component can't be tolerated. A fault in a mechanical system could easily spell bankruptcy to any company whose hands they hold the safety of others in.

Reliability- Capital is tied up in mechanical systems and an expected payout to that system is taken for granted. Maintenance is a requirement of getting the reliability and production from each machine so that it can produce profitability for the risk taken to buy the machine

Longevity - Proper maintenance can extend the useful life of a mechanical system way beyond it's design life. Any extension of design life is a direct return to the bottom line of the company
