Answer:
a) 0.2099
b) 46.5 MPa
c) 233765 N
d) 3896 W
Explanation:
a)
r = (A'' - A') / A'', where
A'' = 1/4 * π * D''²
A'' = 1/4 * 3.142 * 90²
A'' = 6362.55 mm²
D' = D'' - d = 90 - 10 = 80 mm
A' = 1/4 * π * D'²
A' = 1/4 * 3.142 * 80²
A' = 5027.2 mm²
r = (A'' - A') / A'
r = (6362.55 - 5027.2) / 6362.55
r = 1335 / 6362.55
r = 0.2099
b)
Draw stress = σd
Y' = k = 105 MPa
Φ = 0.88 + 0.12(D/Lc), where
D = 0.5 (90 + 80) = 85 mm
Lc = 0.5 [(90 - 80)/sin 18] = 16.18 mm
Φ = 0.88 + 0.12(85/16.18) = 1.51
σd = Y' * (1 + μ/tan α) * Φ * In(A''/A')
σd = 105 * (1 + 0.08/tan18) * 1.51 * In(6362.55/5027.2)
σd = 105 * 1.246 * 1.51 * 0.2355
σd = 46.5 MPa
c)
F = A' * σd
F = 5027.2 * 46.5
F = 233764.8 N
d)
P = 233764.8 (1 m/min)
P = 233764.8 Nm/min
P = 3896.08 Nm/s
P = 3896.08 W
Answer:
15.65 MPa 150 times of human body internal pressure
Explanation:
Given:
- Depth of the ocean for offshore drilling d = 1 mile
Find:
Determine the pressure at that location
What would happen to an unprotected, exposed person at that depth?
Solution:
- The pressure at a certain depth of a fluid can be calculated with:
P = p_w*g*d
Where, P is the pressure , p_w is the density of water ( 997 kg / m^3 ).
- Hence @ d = 1.0 mile = 1.6 km = 1600 m:
P = 997*9.81*1600
P = 15.65 MPa
- Whereas the pressure inside a human body is 101 KPa, Pressure under ocean @ 1 mile of depth is 150 times in magnitude, enough to crush the human body!
Answer:
The answer is "Both Technician A and Technician B".
Explanation:
The cylinder Testing is intended to assess locomotive inconsistency in CNS rodents, for example, whenever the animal moves within a transparent plastic tube, its preliminary activity is registered as it rises against the stadium wall.
In the given question both technicians are correct because both are reliable ways to check cylinders and the influence of the belief if every pathway has many more advantages than each other.
Answer:
Explanation:
The pump is modelled after applying Principle of Energy Conservation, whose form is:
The head associated with the pump is cleared:
Inlet and outlet velocities are found:
Now, the head associated with the pump is finally computed:
The power that pump adds to the fluid is:
Answer: Collect more information about the extent to which this reported behavior is impacting others
Explanation:
The options are:
a. Collect more information about the extent to which this reported behavior is impacting others.
b. Tell the CEO about what you have uncovered and ask for her permission to speak about it with the CFO.
c. Focus on the CFO’s work performance since his personal behavior is inappropriate in the workplace.
d. Inform the human resources department that there is a potential problem.
Given the information provided in the question, the most effective next step in the process will be to collect more information about the extent to which this reported behavior is impacting others. This will be vital in determining whether what is being said about the Chief Financial Officer is true or not and also to know if true, whether it has an affect on the performance of affected employees in the organization.
Option B is wrong as telling the CEO right away isn't the next step as adequate information must be gathered first.
Option C is also wrong as the focus shouldn't be on his work in the organization alone. His personal behavior should be addressed as well if he's wrong. A great organization is made up of great individuals with good behaviors.
Option D is also wrong as the next step should not be to inform the human resource.
Therefore, the correct option is A.
