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.

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 .
