Answer:

44027.28 Joules

Explanation:

We know that Potential Energy of a body of mass 'm'  is given by

Potential Energy = m\times g\times h

where

g= acceleration due to gravity with value = 9.81m/s^{2}

h = height above the ground level

Applying given values in the formula we get

Potential Energy = 60kg\times 9.81m/s^{2}\times74.8m

Thus Potential Energy= 44027.28Joules

Potential Energy= 44.027Kilo-joules

Explain the differences between planned and predictive maintenance.
sveticcg [70]

Answer:

Planned maintenance refers to any scheduled activity carried out to check a machine is working ok and diagnose procedures to fix it if need it. On the other hand, predictive mainteance is all the techniques which help to define if a machine requires or not maintenance activities so far.

Explanation:

Planned maintenance is based on preventive routines to ensure a machine is working in acceptable conditions and at the same time prevent them to change to risky values performing acticities like parts replacement, cleaning,  etc. The key of this maintenance is schedule, that is to say, is a maintenance that has to be carried out constantly each certain time. Predictive maintenance is different because it is used to define if a machie needs any kind of inspection or if, on the contrary, the machine can continue operating without any intervention. The good point about predictive maintenance is the capability of telling when a maintenance is required and when is no necessarily required which is ideal to save costs.
