Answer:
The infiltration rate is of 0.042 m^3/s.
Explanation:
The total volume of the room is:
V = 3 * 10 * 20 = 600 m^3
If the air infiltration rate is of 1/4 volume per hour:
v = V/4 * 1 hour /3600 seconds
Replacing:
v = 600/4 * 1/3600 = 0.042 m^3/s
The infiltration rate would then be of 0.042 m^3/s.
Answer:

The probability that the error occurred when Engineer 2 made the mistake is 0.462 on the other hand the probability that the error occurred when the engineer 1 made the mistake is 0.538
Explanation:
Let denote the event that the 1st engineer does the work.so we write
=0.7
Let denote the event that the 2nd engineer does the work .So we write
=0.3
Let O denote the event during which the error occurred .so we write
=0.02(GIVEN)
=0.04(GIVEN)
- The probability that the error occurred when the first engineer performed the work is
- The probability that the error occurred when the first engineer performed the work is
Now we need to find when did the error in the work occur so we will compare the probability of the work done by <u>engineer 1 </u>and <u>engineer 2 </u>
<u></u>
<u>lets find the Probability of the Engineer 1</u>
<u>Using Bayes theorem,we get</u>
<u></u>
<u></u> =0.02*0.7/0.02*0.7+0.04*0.3 = 0.014/0.026=0.538
<u>lets find the Probability of the Engineer 2</u>
<u></u> =0.04*0.3/0.02*0.7+0.04*0.3=0.012/0.026=0.462
Since ,0.462<0.538 so it is more prominent that the Engineer 1 did the work when the error occurred
Answer:
Question 1 A 1020 Cold-Drawn steel shaft is to transmit 20 hp while rotating at 1750 rpm. Calculate the transmitted torque in lbs. in. Ignore the effect of friction. Answer with three decimal points. 60.024 Question 2 Based on the maximum-shear-stress theory, determine the minimum diameter in inches for the shaft in Q1 to provide a safety factor of 3.

Answer:
Opened Push-button Switch (i.e. a PTM Switch)
Explanation:
Tha's just another symbol for a switch, but this one specifies that the switch is a push-button type of switch.
Since it's not touching and completing the line, the state of the switch is initially open.
