Dear Employees:
Our company has been awarded a contract to construct a space station over the next several years. We have selected a specific design for the space station and the blueprint has been drawn. Before we begin to set a construction schedule and order materials, we need actual construction information. Our company, therefore, is interested in improving the original estimates by building some prototypes to determine the amount of raw materials and the time required to complete the terms of this contract.
Our company will commission several construction crews to build the prototype space station. Using the information recorded from this initial sample, the company will create long term projections and material orders. As designated construction crews, you are formally commissioned to plan and build a prototype space station as accurately and quickly as possible. Each construction crew member will receive a blueprint of the space station. Each crew will receive a construction plan sheet and construction budget sheet. Each construction crew must determine the amount of raw material needed, estimate the amount of time needed to construct a space station, create a budget, and write a construction plan before the building starts.

The Space Station
Construction Plan Sheet
-
1. Construction Plan: Each crew must submit a construction plan with a construction budget. This plan should detail the way the Space Station Module is to be built, including an explanation of tasks, strategies, construction methods, resource management, and duality checks. Time, cost, and the degree of cooperation are all equally important.
-
2. Construcion Budget: Each construction crew should estimate the amount of construction time needed, determine the amount of raw materials required, and total their cost projection. Labor costs are determined at a rate of $12,000 per minute. Raw materials costs are $12,200.00 per beam and $97.50 per bolt and nut. These amounts make up the budget.
-
3. Acquire Raw Materials: Once a crew submits a budget, the requested raw materials will be delivered to each team. Each crew will want to verify that all of their requested materials are delivered since no raw materials will be delivered during construction. No excess materials may be sold back after construction begins. Additional materials may not be purchased until after the inspection.
-
4. Build Space Station Module: Each crew begins construction at a given signal. When a construction crew completes the Space Station Module, the finished time is recorded. Specific roles may be assigned but all must participate in the actual construction of the bridge.
-
5. Space Station Inspection: Each Space Station Module is inspected by an independent inspector after all space stations are built. The inspector guarantees that the space station is constructed in accordance with the company blueprint. All joints must be securely fastened. If a Space Station Module does not meet the standard, a delay is charged, and the space station must be adjusted. The total time accumulates while any revisions are made. An additional delivery fee of $1500.00 is added to the raw material fee if any additional materials are needed.

The Solar System
Kepler’s three laws of planetary motion. The first law states that the planets orbit in ellipses with the sun at one focus. Describes the foci of ellipses as the two points, the sum of whose distances to any point on the ellipse is a constant. Compare the foci of an ellipse to a circle, whose center is defined as the point whose distance to any point on the circle is a constant. Kepler’s second law states that a planet sweeps out equal areas in equal times. This has the consequence that a planet speeds up when it is closer to the sun, and slows down when it is farther away. Kepler’s third law is the relationship between a planet’s distance to the sun and its orbital period.
To calculate orbital speed, use the formula
V= (2 ¹ a) / P Where
V = orbital speed
a = orbital radius, (the average distance of the planet from the sun),
P = orbital period in seconds = P in years x 3.16 x 10^7 (approximately)
¹ = 3.14
|
Example:
|
Orbital Velocity of Earth
|
V = 2¹a / P = 2(3.14)(14.86x10^7)/1(3.16x10^7) = 2(3.14)(14.86/1(3.16)
= 93.3208/3.16 = 29.53 km/sec
Make a table that contains data about the sizes and periods of planetary orbits around the sun. Use the data to calculate the orbital speed of each planet. You can assume that the shapes of the orbits are circles. The orbits are really ellipses as you have learned, but the flattening is very slight, and using circles simplifies the calculations.

Make a Solar System
What is the solar system? The solar system, then, is the system of the SUN. This system is made up of the sun and all the objects that travel around the sun. These of the sun travel in “paths” called orbits. They are held in their orbits by the sun’s gravity The path’s of orbit is on ellipse. And the sun is not exactly in the center of the ellipse. It is slightly off center. For these reasons, the planets are not the same distance from the sun at all times.
In the space below, draw and label the solar system. Make the solar system to scale. Remember the solar system is an ellipse not a circle.
