3. An underground copper pipe is used to transport oil under a factory. It is very important that this pipe does not oxidize, so engineers use impressed current cathodic protection. a. Would zinc be an appropriate metal to use for cathodic protection? Why or why not? (4 points) b. Engineers attach a sacrificial anode to the copper pipe. To use impressed current cathodic protection, they must attach a battery between the cathode and anode. Which material should the positive side of the battery be attached to? Explain how you know. (4 points)

Answers

Answer:

a) Copper corrosion is prevented by an external current source that provides a condition around the copper that halts the rust through current cathodic protection

Due to the location of the pipeline, an material such as graphite, titanium, or niobium can be used which lasts longer that zinc can be used for longevity of the protection

b) The positive side of the output DC terminals are attached to the anodes such as graphite, while the negative terminals are connected to the copper pipe to be protected

Explanation:

Making the protected metal the cathode will make the metal be the source of electrons into the reaction taking place such that the release of the positive metal ions that results in disintegration takes place at the anode and as such the protected metal made the cathode, to which the negative terminal of the battery is attached is protected.

If sail boats A and B are approaching each other with the wind on different sides, why is vessel A considered the give-way vessel (vessel that must take early and substantial action to avoid a collision)?

Answers

Answer:

The reason is because when the wind approaches each sailboat from a different side, the sailboat that the wind approaches from the port side, which is the left side is the give-way vessel.

Whereby the wind approaches the vessel A from the port (left) side then vessel A is considered the give-way vessel

The give-way vessel is the vessel that will have to take expeditious steps to create  access for the other vessels by either changing course, stopping, or moving with reduced speed

Answers

Answer:

The best way to ensure that OSHA will conduct a site inspection is by the submission a signed (by a current employee or employee representative) Formal Written complaints following OSHA guidelines (which can be found in the  Council of Safety and Health (COSH) website) which will enable the commencement of process for an on site inspection

As such it is advisable to go through the following procedure before, filing a complaint

1) Talk to your workers union about the hazard

2) If you do not belong to a union, talk to your co-workers

3) Inform your employer who has responsibility for on the job safety

4) Speak or have a meeting with OSHA so as to receive guidance before filing a complaint

Explanation:

If you think a hazard is serious, the best way to ensure that OSHA will conduct a site inspection is to file a complaint.

Hazard simply means a potential source of harm. It should be noted that hazards can have detrimental effect on the health of an individual.

If you think a hazard is serious, the best way to ensure that OSHA will conduct a site inspection is to file a complaint asking OSHA to inspect the workplace. In a situation whereby OSHA finds a serious hazard, it'll be kept confidential.

2. What is the charge, expressed in micro coulombs on two equally and similarly charges spheres placed in air with their centres 30 cm apart repelling each other with a force of 120 mgm.

Answers

Answer:

q = 0.1086 micro Coulombs

Explanation:

By Coulombs law, we have;

[tex]F =k \times \dfrac{ q_1 \times q_2}{r^2}[/tex]

Where;

F = The electric force = 120 mgm

q₁ and q₂ = Charge

r = The separating distance = 30 cm = 0.3 m

k = 8.9876×10⁹ kg·m³/(s²·C²)

Where, q₁ and q₂, we have;

[tex]F =k \times \dfrac{ q^2}{r^2}[/tex]

Whereby the force is the force of 120 milligram mass, we have;

0.00012 × 9.81 = 000011772 N

[tex]q = \sqrt{ \dfrac{ F\times r^2}{k}}[/tex]

Substituting the values, we have;

[tex]q = \sqrt{ \dfrac{ 000011772 \times (0.3)^2}{8.9876 \times 10^9}} = 1.086 \times 10 ^{-7} \ Coulombs[/tex]

q = 0.1086 micro Coulombs.

a steal bar with 1 in diameter has been subjected to a tensile force of 3 tons find tensile stress in the bar

Answers

Answer:

stress = 8,556 Psi.   or  (stress = 59 Mpa)

Explanation:

stress = force / area

force P = 3 tons (convert to lbs. for units consistency)

1 ton = 2240 lbs.

P = 6,720 lbs.

steel bar Diameter D = 1 in. (convert to d

Area of steel bar = (π *  1²) / 4 = 0.785 in²

therefore, stress = 6720 lbs. / 0.785 in²

stress = 8,556 Psi.

in Mpa ----- 8556 Psi * 0.00689476 MPa/Psi = 59 Mpa

The correct option is;

C. Bottom-up design

Explanation:

The bottom-up design is meant for system redesign or re-engineering of an existing design involving component upgrading or legacy systems replacement

The bottom-up design approach is also meant for applications where there is a new interface requirement for the original system in order to determine the functionality of the newly combined systems and also where a novel component is incorporated into the existing design.

The bottom-up approach starts with the analysis of the interoperability of the components to the modules and eventually the analysis of the system requirements.

You may need to improve your ability to express yourself in writing.

To some degree, most organisations rely on the accurate transfer of information and that calls for the accurate use of language. When speaking, most people make multiple errors of grammar and vocabulary, and nobody seems to mind. But when you are doing business at work, then the business agreement is usually in the form of a written document; and that document has to be worded properly.

A: Stop within 10 feet of the intersecting roadway, on top of the pedestrian crosswalk if there is one.
B: Wait for pedestrians in the crosswalk to cross, then stop on the pedestrian crosswalk.
C: Stop before entering the pedestrian crosswalk.

Answers

Answer:

The answer is B. Wait for the pedestrians in the crosswalk to cross, then stop on the pedestrian crosswalk.

Based on the concept of road usage, and the available options, when you arrive at an intersection with a stop sign in your direction, if there is no marked stop line, you must Stop before entering the pedestrian crosswalk.

What is Pedestrian Crosswalk?

Pedestrian Crosswalk is a term that is used to describe a place designated for pedestrians to cross a road, street, or avenue.

Generally, the term "pedestrian crosswalk" is also used in the Vienna and Geneva Conventions, both of which pertain to road signs and road traffic.

In this case, it is expected that when you arrive at an intersection with a stop sign in your direction, if there is no marked stop line, you must stop at the edge of the intersection just before entering the crosswalk or intersection.

It's important to come to a complete stop to ensure that it is safe to proceed before proceeding through the intersection. Be careful and aware of your surroundings to ensure a safe and steady flow of traffic.

Hence, in this case, it is concluded that the correct answer is option C. Stop before entering the pedestrian crosswalk.
