Concepts of Engineering Midterm Study Guide for Semester 2

1.       Advantages of Pneumatics over Hydraulics– (write/type the 5 key things from the flashcards

Commonly seen hydraulics based equipment types are hydraulic presses, hydraulic hoppers, hydraulic cylinders, and hydraulic rams.

Pneumatic powered equipment is more suitable, particularly in industries where the factory units are plumbed for compressed air.

In order to affect mechanical motion, pneumatics employs compression of gases, based on the working principles of fluid dynamics in the concept of pressure.

Any equipment employing pneumatics uses an interconnecting set of components.

Hydraulics means use of pressurized fluids to execute a mechanical task.

Chapter 18 - (write/type 3 key things from the flashcards here)

Newton’s third law is every action has an equal and opposite reaction.

Jet airplanes, fireworks, and recoil guns apply to Newton third law.

Resistance -opposes forward movement...

2.       Chapter 19 -  (write/type 5 key things from the flashcards here)

Gasoline engines take in a mixture of gas and air and Diesel engines take in just air, compress it, and then inject fuel into the compressed air.

Pressure (P) is proportional to the temperature

P=F/A, therefore F= an x P.

Hybrid vehicles have both gas engines, and electric motors and batteries, so they can use both energy sources

Diesel engines are more powerful, and therefore are used to power trains, cargo ships, and other heavy vehicles.

No explosions inside of the combustion chamber. Is requirement for the sting engine?

\

Correct Response B: It is given in the question that the numbers in the diagram are rounded to the nearest whole number. Let w represent the length of the smallest side of the rectangle and l represent the length of the longest side of the rectangle. Because of the rules of rounding, the smallest possible value of w is 1.5 in. Note that if we were smaller, say 1.49 in., then it would have been rounded down to 1 in. The same line of reasoning applied to l indicates that the smallest possible value of l is 3.5 in. Since the area of a rectangle A is given by A = l × w, the smallest possible value for the actual area of the given rectangle is A = (1.5 in.)(3.5 In.) = 5.25 square inches. The largest possible value of w is 2.49 in. to two decimal places, 2.499 in. to three decimal places, 2.4999 in. to four decimals places, etc. Likewise, the largest possible value of l is 4.49 in. to two decimal places, 4.499 in. to three decimal places, 4.4999 in. to four decimal places. Since these values are very close to, but less than 2.5 in. and 4.5 in., respectively, we can conclude that the area of the rectangle must always be less than (2.5 in.)(4.5 in) = 11.25 square inches. Therefore, the area of the rectangle must be greater than or equal to 5.25 square inches and less than 11.25 square inches (5.25 ≤ a < 11.25). Of the answer choices given, only 5.5 square inches is in this range.

Incorrect Response A: This response comes from correctly noting that the smallest possible value for the side lengths are w = 1.5 in. and l = 3.5 in., but by finding the sum of l and w instead of the product of l and w. The sum of l and w is not the area of the rectangle. The sum would be 5.0 inches, not 5.0 square inches.

Incorrect Response C: This response most likely results from incorrectly calculating the largest possible area of the rectangle, as described above. Incorrect Response D: This response comes from using the values given in the diagram, and then finding the perimeter of (i.e., the distance around) the rectangle, instead of the area of the rectangle. The perimeter would be 12.0 inches, not 12.0 square inches.

Incorrect Response D: This response comes from using the values given in the diagram, and then finding the perimeter of (i.e., the distance around) the rectangle, instead of the area of the rectangle. The perimeter would be 12.0 inches, not 12.0 square inches.

Putt Putt Boat Benchmark

 The Putt Putt  was so far the hardest project that we  worked on . The boat seem easy to do make,  but took more reading and more thinking skills  than any other project that we ever did . The putt putt boat  was very intersing becuase i wanted to see if i could really get the boat to more and make the moise  like the man in the video that we watch  did . I hope when  we are revering the project me reach the  goal  and make it more effeicent .

FBLA - Future Business Leaders of America

 
Go back and look at the information about the history of technology – know your time periods and definitions from the assignment titled “Designing your vocabulary words.”

Technology: the study of the designed world. Used to solve practical problems and extend human capabilities. Developments in technology are evolutionary, and are often the result of a series of refinements to an idea or basic invention.

Impacts of Technology: are divided into four categories: social (the impact on people), political (the impact on policy and laws), cultural (the impact on human achievement), and economic (the impact on the economy).

Paleolithic Age: the Old Stone Age, occurred between 500,000 BC and 10,000 BC and is marked by improvements to diet and security allowing the population to grow.

Mesolithic Age: the Middle Stone Age, occurred between 10,000 BC and 4,000 BC and is marked by the domestication of animals and agriculture.

Neolithic Age: the New Stone Age, occurred between 4,000 BC and 2,300 BC and is marked by specialization, division of labor, and the use of math and documentation of concepts.

Bronze Age: the architectural period that includes combining copper and tin to produce bronze; occurred between 2,300 BC and 700 BC.

Iron Age: the architectural period marked by the use of iron and steel; occurred between 700 BC and 450 AD.

Middle Ages: the architectural period after the Roman Empire; divided into Early Middle Ages, High Middle Ages, and Late Middle Ages; occurred between 450 AD and 1,400 AD and marked by the development of tools of war.

Renaissance: the architectural period marked by the revival of classical influence and the sharing of ideas; occurred between 1,400 AD and 1,750 AD.

Industrial Age: the architectural period marked by the first use of complex machinery, factories and urbanization, occurring between 1,750 AD and 1,950 AD.

Information Age: the architectural period marked by information sharing, gathering, manipulation, and retrieval; occurred between 1,950 AD and present.

 8 . Know what the purpose of an engineer’s design notebook is (format, design, etc.).

Purpose

Keeping notes of what is said in every class you take is something you have come to expect. You also have learned in mathematics class, for example, that a record of your work helps you to explain to your teacher what you wanted to do when you solved a mathematics problem. The same is true with engineers. They must keep a record of the work they do toward developing a solution, the processes they use in creating the solution, and a record of their solutions. The engineer’s notebook is so important that it is considered a legal document.

This activity is designed to help you set up your notebook and to learn to keep records of the work you will do in this class. In addition, you will be asked to take notes of the information you learn and the work you complete.

20.  Know the difference between wire frame models, surface, and solid models

Wire-frame models are undoubtedly the least complicated when compared to the other two categories. In a wire-frame model, all the surfaces of the physical object (including the opposite ends and internal components) are represented through bare lines and arcs. Due to the simple drawing techniques used in wire-frame models, they may not be suitable for complicated projects that require uncompromising realistic effects.

Surface models are more realistic than wire-frame models, but not nearly as much as solid models. Unlike wire-frame models, they are created by merging 3D surfaces instead of bare lines and arcs. A three-dimensional surface is more like a piece of paper that can be placed at various angles to specify different shapes. So basically, in surface modeling, designers join multiple surfaces to give it the desired shape as well as to hide the backgrounds that need not be seen.

Solid models are vastly different from the other two types of models on the ground that they are solid inside. In other words, solid modeling can be referred to as a technique used to combine a number of "solid objects" into a single 3D design. Much like a physical object, a solid model also has additional properties like density, weight and center of gravity because of which it is most preferred choice when it comes to designing prototype of a mechanical product.
