Answer:

The correct solution is "0.66104".

Explanation:

Given:

Component 1,

$\beta=1.3$

$\gamma=24,000 \ hr$

Component 2,

$\beta = 1.9$

$\gamma=18,000 \ hr$

Component 3,

$MTTF=48,000 \ hr$

Now,

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

⇒ $Rs(t=6000)=\frac{3}{\pi} R_1\times R_2\times R_3$

$=[e^{-(\frac{6000}{24000} )^{1.3}}]\times [e^{-(\frac{6000}{18000} )^{1.9}}]\times [e^{-(\frac{6000}{48000} )}]$

$=0.66104$

Thus the above is the correct solution.

A crate weighing 1000 Newton's needs to be lifted at a constant speed from the ground to a loading dock 1.5 meters high in 5.0 s

miskamm [114]

Answer:

the Power required is 300 W

Explanation:

We know that the definition of work is given by the following expresion:

$W=F*d$

the distance is 1.5 meters and the Force is equal to 1000 N.

Replacing this values in the work expresion

$w= 1000 *1.5 = 1500 J$

And the power is equal to the amount of work done in a given time, therefore we have:

$Power = \frac{work}{time} \\$

Time in seconds

$Power = 1500/5\\\\Power = 300 watts$
