Abstract A component failure has the potential to significantly impact the cost, manufacturing schedule, and/or the perceived reliability of a system, especially if the root cause of the failure is not known. A failure analysis is often key to mitigating the effects of a componentlevel failure to a customer or a system; minimizing schedule slips, minimizing related accrued costs to the customer, and allowing for the completion of the system with confidence that the reliability of the product had not been compromised. This case study will show how a detailed and systemic failure analysis was able to determine the exact cause of failure of a multiplexer in a high-reliability system, which allowed the manufacturer to confidently proceed with production knowing that the failure was not a systemic issue, but rather that it was a random “one time” event.

An analysis is presented of a reeving arrangement suitable for the hoisting of critical materials requiring fail-safe criteria. The system consists of two independent wire ropes symmetrically threaded through the crown and lower blocks and reeved by a single takeup drum. The analysis provides for the load in each line of the wire rope remaining after failure of one rope occurs. The motion of the lower block and load are also provided for the variety of failure conditions considered. The analysis is useful to predict the effect of various design parameters on the integrity of system in the event of a single component failure.
