QUESTION 2: (2 pts) The failure mode being studied is the stoppage of agitation in a tank before mixing is complete. This becomes the top event. Further team study indicates that this will occur if any of the following occurs: Power loss Timer shuts off too soon Agitator motor failure Agitator power train failure Power loss will occur if external power source fails and the backup generator fails. Timer shuts off too soon if it is set incorrectly or it has a mechanical failure. Agitator motor fails if overheated or a fuse or capacitor fails. Agitator power train fails if both belts A and B break or clutch fails. This is symbolized by the FTA diagram shown below.
