If a system reliability of 0.998 is required, what reliability of two components in series is required?
1 answer:
Two components in the series have dependability of .
We need both two components to function in order to determine the engine's reliability. Since each component has dependability of , we must determine the likelihood that both components will function in order to determine the engine's reliability.
The possibility that a product, system, or service will function as intended for a predetermined amount of time, or that it will run faultlessly in a predetermined environment, is known as reliability.
By multiplying each of the reliability coefficients, we may calculate this probability:
P is equal to after being rounded to three decimal places.
The engine has a dependability rating of .
Hence,
Two components connected in series have dependability of .
Reliability and failure probability are complimentary, or.
In various cases, the distinctive qualities of a series arrangement will be demonstrated. is the resultant reliability of two components.
A component's reliability is assessed in light of the application for which it will be utilised. An operational profile gives a description of the situation. Software reliability can be calculated or measured.

Answer:
Explanation:
The horizontal distance covered by the ball in the falling is only determined by its horizontal motion - in fact, it is given by
where
is the horizontal velocity
t is the time of flight
The time of flight, instead, is only determined by the vertical motion of the ball: however, in this problem the vertical velocity is not changed (it is zero in both cases), so the time of flight remains the same.
In the first situation, the horizontal distance covered is
in the second case, the horizontal velocity is increased to
And so the new distance travelled will be
So, the distance increases linearly with the horizontal velocity.
Answer:
Part a)
so here the angle made by the string is independent of the mass
Part b)
Explanation:
Part a)
Let the string makes some angle with the vertical so we have force equation given as
so we will have
so here the angle made by the string is independent of the mass
Part b)
Now from above equation if we know that angle made by the string is
so we will have
