About Project and there example, characteristics.

Pipes were introduced in the very earliest days of the practice of hydraulics. Their common place used today makes them of great importance that the laws governing the flow in them should be fully understood. Some loss of energy is inevitable in the flow of any real fluid.

I WOULD NEED YOUR EMAIL TO SEND YOU THE CAD FILE AND THEN YOU’LL NEED TO SEND IT BACK TO ME WHEN YOU’RE DONE VIA EMAIL.

OVERVIEW

In this Final Project Assignment, you will have the opportunity to work on a more complex

problem and present your results. You should use the knowledge you have gained through the 6

AutoCAD assignments to demonstrate your mastery.

INSTRUCTIONS

1. Open the provided drawing Final Project.dwg.

2. Set drawing units to ENGINEERING.

3. Draw the roadway centerline and the edges of the roadway as detailed in the textbook in

Chatper 15 (20 foot wide road). You can determine at what location youd like the road

to run, but it should run from left to right in straight path across the plan view.

4. Create the elevation view below the plan view by utilizing the centerline elevations.

Make sure to then include the proposed profile for your roadway, keeping in mind that

youll want to minimize cut and fill work.

5. Delineate the earthwork. There is an example of this process in chapter 16. You can

utilize a +/- 2% slope.

a. Draw vertical lines between two profiles.

b. Delineate cut and fill on the lower side of the road.

c. Extend the projection lines to the other edge of the road.

d. Repeat the delineation process for the other edge of the road.

e. Hatch and label the cut and fil as well as the roadway.

6. Utilizing the PnP layout tab, set the viewport scale to 1:400.

7. Update the text blocks in the title block for this class.

8. Plot to a .pdf utilizing the name format: LastName_ProjectNumber_Date.pdf.

9. Save the AutoCAD file utilizing the following file name format:

LastName_ProjectNumber_Date.dwg.

10. Submit both files to complete the project.

– Scale and shape the cube to match the rectangular form of the villa.

– Create the slanted roof/angled top edges as shown in the reference.

– Add thickness to walls where needed.

– Model the large front glass facade:

– Create a wide opening on the front side

– Insert glass panels using separate objects

– Add terrace (deck) in front of the glass facade:

– Use a plane and extrude slightly

– Keep proportions realistic

– Add simple interior elements (optional but preferred):

————————————-

PART 5: CAMERA SETUP

Use the SAME camera angle for both versions:

– Set a perspective front angle (similar to reference image)

– Make sure the full building is visible

– Frame the terrace and glass facade clearly

————————————-

You must render the following images:

1) BEFORE MATERIAL IMAGE:

– Model without white material (raw/grey look)

2) AFTER MATERIAL IMAGE:

– Same camera angle

– Ensure no noise and good lighting balance

– Output images in high resolution

————————————-

FINAL REQUIREMENTS:

RESEARCH PAPER ASSIGNMENT INSTRUCTIONS

The research paper should incorporate Biblical worldview of some topic of a natural and

dynamic system. There are several dynamic natural systems arround us. For example, flying

birds, moving water or river, a moving cloud, suns or other planets motion relative to the earth,

a fish moving in water etc. In this paper, you will be selecting a natural dynamic system and

discuss the system based on the following points:

a) Describe the path(s) of motion of the component(s) and select appropriate coordinate

axes to describe the motion. Discuss why the selected coordinate axes are best to describe

the motion of the selected system.

b) Discuss the importance of the dynamic system and its motion for the functionality of

other systems that depend on it. State any assumptions.

c) Draw (sketch or use software) free-body and kinetic diagrams of the system. Use

appropriate kinematics and kinetics equations and write equation of motion for the

system using the selected coordinates.

d) Romans 1:20 says For since the creation of the world God’s invisible qualities-his

eternal power and divine nature-have been clearly seen, being understood from what has

been made, so that people are without excuse. Does the dynamic natural system you

selected indicate the existence of a supernatural being? Why or why not? Also comment

on the intelligence of the design of the system and its benefit to humanity.

Deliverables/Expectations:

e) Your writing should be well-organized and free of grammar, punctuation, and spelling

errors. Your paper should have the following components:
