Elizabeth Irwin's design team has proposed the following system with component reliabilities as indicated:
R2=0.88
R1=0.92
R4=0.92
R3=0.88
The overall reliability of the proposed system = % (enter your response as a percentage rounded to two decimal places).
Hint: The system functions if either R2 or R3 work.
The semiconductor used in the Sullivan Wrist Calculatorhas five circuits, each of which has its own reliability rate.
Component 1 has a reliability of .90; component 2, .95; com-ponent 3, .98; component 4, .90; and component 5, .99. What is
the reliability of one semiconductor?
An engine system consists of 2 main components in a series, all having the same reliability. Determine the level of reliability required for each of the components if the engine is to have a reliability of 0.989. round answer to 4 decimal places.
