learning objectives and outcomes

engage in a discussion on strategies to minimize recovery time in a windows environment.

ken 7 windows limited has added several new servers and workstations to the ken 7 domain to support the new enterprise resource planning (erp) software. while losing a workstation to a disastrous event would be uncomfortable, losing a server would have a far greater impact to ken 7 windows. therefore, it’s important that plans are in place to recover from any unexpected situation in as short a time as possible.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Machinery that is a key part of the process and without which the plant or process cannot function is classifed as: (clo4) a)-critical machinery b)-essential machinery c)-general purpose machinery d)-none of the specified options.

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero
