If a system reliability of 0.998 is required, what reliability of two components in series is required?

Physics
1 answer:
Yakvenalex [24]1 year ago
3 0

Two components in the series have dependability of 0.996.

We need both two components to function in order to determine the engine's reliability. Since each component has dependability of 0.998, 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 10 reliability coefficients, we may calculate this probability:

P = 0.998^2 = 0.996004

P is equal to 0.9966 after being rounded to three decimal places.

The engine has a dependability rating of 0.996.

Hence,

Two components connected in series have dependability of 0.996.

<h3>What is the compound of reliability ?</h3>

Reliability and failure probability are complimentary, orF= 1 - R.

In various cases, the distinctive qualities of a series arrangement will be demonstrated. R = R 1 R 2 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.

A 2000 kg car experiences a braking force of 10000N and skids to a 14 m stop. What was the speed of the car just before the brak
Fudgin [204]

Answer:

V = 11.83 m/s

Explanation:

Given the following data;

Mass = 2000 kg

Force = 10000N

Distance = 14 m

To find the final velocity of the car;

First of all, we would determine the acceleration of the car;

Acceleration = force/mass

Acceleration = 10000/2000

Acceleration = 5 m/s²

Next, we would use the third equation of motion to find the final velocity;

V^{2} = U^{2} + 2aS

Where;

V represents the final velocity measured in meter per seconds.

U represents the initial velocity measured in meter per seconds.

a represents acceleration measured in meters per seconds square.

S represents the displacement measured in meters.

Substituting into the equation, we have;

V² = 0² + 2*5*14

V² = 0 + 140

V = √140

V = 11.83 m/s

How can we use thermal energy to our advantage?
devlian [24]

Answer:

One of the primary advantages of thermal power is that the generation costs are extremely low. No fuel is needed to generate the power, and the minimal energy needed to pump water to the Earth's surface can be taken from the total energy yield.

which unit of measure would scientist use to measure the thickness of rock layer, created as a result of volcanic activity
frozen [14]
A scientist would use a unit of length appropriate for the magnitude of what he or she is measuring. In this case, since rock is built up very slowly, they would probably use millimetres or centimetres. In some cases they may use meters.

A woman is sitting at a bus stop when an ambulance with a siren wailing at 317 Hz approaches at 69 miles per hour (mph). Assume
Solnce55 [7]

Answer:

a)30.67 m/s

b)348,12 Hz

c)32,34 m/s

d)289,69 Hz

Explanation:

a)

To convert 69 mph to m/s we have:

69\times 1.6=110.4\, Km/h=\frac{110.4}{3.6}=30.67 \, m/s

b)

For a resting receiver and an approaching source we have the following Doppler formula:

f=f_0\frac{c}{c-v_s}

where v_s is the source, and c is the speed of sound, f the perceived frequency and f_0 the frequency as perceived by the source. Plugging all the relevant values we get:

f=348,12 \, Hz

c)

Using the same formula as above and solving for v_s we have:

v_s=c\frac{f-f_0}{f}=32,34 \, m/s

d)

Now we have another Doppler formula for a source that is moving away from the receiver:

f=f_0\frac{c}{c+v_s}=289.69 Hz
