Two parallel disks, 80 cm in diameter, are separated by a distance of 10 cm and completely enclosed by a large room at 20°C. The properties of the surfaces are T, = 620°C, E,= 0.9, T2 = 220°C, E2 = 0.45. What is the net radiant heat transfer with each surface? (Do not include back side exchange, only that from the surfaces facing each other.) Answers 1. Hot disk watts a) b) c) Cold disk watts Room watts
Answers
The net radiant heat transfer with each surface is:
a) Hot disk: 3312.65 watts or 3.3 kW ; b) Cold disk: -1813.2 watts or -1.8 kW ; (c) Room: 0 watts or 0 kW.
Given:
Two parallel disks, 80 cm in diameter, are separated by a distance of 10 cm and completely enclosed by a large room at 20°C.
The properties of the surfaces are
T, = 620°C,
E,= 0.9,
T2 = 220°C,
E2 = 0.45.
To find:
The net radiant heat transfer with each surface can be determined as follows:
Step 1: Area of the disk
A = πD² / 4
= π(80 cm)² / 4
= 5026.55 cm²
Step 2: Stefan-Boltzmann constant
σ = 5.67 x 10⁻⁸ W/m²K⁴
= 0.0000000567 W/cm²K⁴
Step 3: Net rate of radiation heat transfer between two parallel surfaces can be determined as follows:
q_net = σA (T₁⁴ - T₂⁴) / (1 / E₁ + 1 / E₂ - 1)
For hot disk (Disk 1):
T₁ = 620 + 273
= 893
KE₁ = 0.9
T₂ = 220 + 273
= 493
KE₂ = 0.45
q_net1 = σA (T₁⁴ - T₂⁴) / (1 / E₁ + 1 / E₂ - 1)
q_net1 = 0.0000000567 x 5026.55 x ((893)⁴ - (493)⁴) / (1 / 0.9 + 1 / 0.45 - 1)
q_net1 = 3312.65 watts or 3.3 kW
For cold disk (Disk 2):
T₁ = 220 + 273 = 493
KE₁ = 0.45
T₂ = 620 + 273
= 893
KE₂ = 0.9
q_net2 = σA (T₁⁴ - T₂⁴) / (1 / E₁ + 1 / E₂ - 1)
q_net2 = 0.0000000567 x 5026.55 x ((493)⁴ - (893)⁴) / (1 / 0.45 + 1 / 0.9 - 1)
q_net2 = -1813.2 watts or -1.8 kW
(Negative sign indicates that the heat is transferred from cold disk to hot disk)
For room:
T₁ = 293
KE₁ = 1
T₂ = 293
KE₂ = 1
q_net3 = σA (T₁⁴ - T₂⁴) / (1 / E₁ + 1 / E₂ - 1)
q_net3 = 0.0000000567 x 5026.55 x ((293)⁴ - (293)⁴) / (1 / 1 + 1 / 1 - 1)
q_net3 = 0 watts or 0 kW

Declaring a variableThe first code declares a variable called num and gives it an initial value of 0. It then enters a while loop that lauches a message box (using window.alert) to print the message "Keep going" as long as num remains less than 5.
If nothing is done within the loop to increment num towards the value 5, the loop will go on endlessly notifying the user to "Keep going".
So, an increment of 1 was added to the loop body to increment the variable num. This makes sure the loop terminates.

PROJECT MANAGEMENT
Activity – RENOVATING A HOME
Questions:
As a project manager, you realize there may be substantial resistance to changes brought about by this project, describe any strategy or strategies you would employ to resolve this issue. (Make mention of any group from which this resistance may originate.)
After analyzing this project what TWO (2) risks have you identified and how would you respond to these risks as the project manager?
Answers
As a project manager, I would employ the following strategy to address resistance to changes in the home renovation project:
Strategy: Effective Communication and Stakeholder Engagement
To address resistance to changes, it is crucial to establish open and transparent communication channels with all stakeholders involved in the project. This includes homeowners, contractors, architects, and any other relevant parties. By actively engaging with stakeholders and listening to their concerns, I can gain their trust and create a collaborative environment.
Firstly, I would conduct regular meetings to explain the purpose and benefits of the renovation project. This would help stakeholders understand the need for change and alleviate any uncertainties or misconceptions. Clear and concise communication is key to ensuring everyone is on the same page.
Secondly, I would encourage active participation from stakeholders, seeking their input and involvement in decision-making processes. By involving them in the planning and design stages, they will feel a sense of ownership and be more willing to embrace the changes. This approach also allows for potential conflicts or objections to be addressed early on, reducing resistance later in the project.
Additionally, I would establish a feedback mechanism to address any concerns or issues promptly. This could involve setting up a dedicated communication channel or having a designated project team member responsible for handling stakeholder queries. Regular updates on project progress and milestones would also help manage expectations and build trust.
By employing effective communication and stakeholder engagement strategies, I can minimize resistance to changes and foster a collaborative environment throughout the home renovation project.

Explain why the difference between engineering strain and true strain becomes larger as strain increases. Is this phenomenon true for both tensile and compressive strains
Answers
The true strain is a more accurate and precise measure of deformation than the engineering strain. At low strains, the engineering strain is a good approximation of the true strain.
As the strain grows, the difference between the engineering strain and the true strain grows, as you’ve stated. When the true strain is substantial, the difference between the two strains is large.
This is due to the fact that engineering strain calculates the change in length as a proportion of the original length, whereas true strain calculates the change in length as a proportion of the current length.

a) How many more men should the contactor add so that he would complete the work on time?

A contractor has a job that should be completed in 100 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 130 days. Of the 80 men, 50 are each paid ₱120.00 a day, 25 at ₱180.00 a day, and 5 at ₱250.00 a day. For each day beyond the original 100 days, a contractor has to pay ₱500.00.
liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.
b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.
The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows: $$LD = (130-100) \cdot 500 = ₱15,000.00$$.
Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$
Thus, we can see that the contractor would save ₱48,900.00 by employing more men and not paying the fine.

The acrylic plastic rod is 200 mm long and 10 mm in diameter. If a tensile load of 300 Nis applied to it, determine: 300 N 300 N 200 mm a)The normal stress b)The final length of the rod , If the strain (c) of the rod is 0.04.
Answers
a) The normal stress on the acrylic plastic rod is approximately 191.013 N/mm².
b) The final length of the rod, considering a strain of 0.04, is 208 mm.
c) The strain (ε) of the acrylic plastic rod is 0.04.
To calculate the normal stress, we use the formula: Normal stress = Force / Area. Given that the force applied is 300 N and the diameter of the rod is 10 mm, we first need to calculate the area of the rod's cross-section.
The area is determined using the formula: Area = π * (radius)². Since the diameter is 10 mm, the radius is half of that, which is 5 mm. Substituting the values into the formula, we find the area. Then, dividing the force by the area gives us the normal stress.
To determine the final length of the rod, we use the formula: Final length = Initial length + (Strain * Initial length). Given that the initial length is 200 mm and the strain is 0.04, we can substitute these values into the formula to calculate the final length.
The strain is a measure of the deformation or elongation of a material relative to its original length. It is calculated using the formula: Strain = ΔL / L, where ΔL is the change in length and L is the original length. In this case, the strain is given as 0.04.

creepbrittledistortionphase slip
Answers
Creep is the time-dependent and permanent deformation of materials when subjected to static mechanical stresses at elevated temperatures, typically greater than 0.4 Tm. Thus, Option A is correct.
This undesirable phenomenon can lead to creep brittleness, distortion, and phase slip, which may limit the lifetime of a part in service.
The term for the time-dependent and permanent deformation of materials under constant load or stress at elevated temperatures is creep, which is often an undesirable phenomenon and can limit the lifetime of a part. Creep occurs when the temperature is greater than 0.4 times the melting point of the material, and it is influenced by factors such as load, temperature, and time.
Creep behavior can be characterized by the creep rate, which is the rate of deformation over time, and the creep curve, which shows the relationship between deformation and time. Understanding creep behavior is important for designing materials and structures that can withstand high temperatures and mechanical stresses over long periods of time.
