A production machine that consists of three components connected in series. The first component follows Weibull probability distribution with shape parameter of 1.3 and scale parameter (characteristic life) of 24,000 hr. The second follows Weibull probability distribution with shape parameter of 1.9 and scale parameter (characteristic life) of 18,000 hr. The third component follows exponential distribution with MTTF= 48,000 hr. Find the reliability of the system at t = 6000

The correct solution is "0.66104".

Explanation:

Given:

Component 1,

Component 2,

Component 3,

Now,

At t = 6000 hr, the system reliability will be:

⇒

Thus the above is the correct solution.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
