The Sender of information is called the what?
Source?
Encoder?
Transmitter?
Decoder?
Receiver?
What is "the Source". The Source creates the message that is sent to the Receiver.
What is a Prototype?
What is "a rough draft or an early model of your design that will be improved as you work through the Engineering Design Process".
True or False
You have to do the steps of the Engineering Design Process in order.
What is "false". The steps of the Engineering Design Process do not have to be done in order. You can go through the Engineering Design Process many times, skipping over steps you do not need, and focusing on the steps you do need to finish your project.
The production of large quantities of items is called what?
What is "mass production".
What is a scale drawing?
What is "a drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount".
WiFi, Bluetooth, radio waves, and cellular data are all examples of what part of the Communication System?
Source?
Encoder?
Transmitter?
Decoder?
Receiver?
What is a "transmitter".
The students in a class would like to make 20 paper sailboats for a race. The students will select one design and collect the materials they need to construct the boats.Which of the following is the best way for the students to be sure the paper sailboats will float without tipping over in the water?
A.) construct a prototype of a boat for testing
B.) calculate the total mass of all of the finished boats
C.) determine the total amount of weight each boat can carry
D.) test the strength of each material used to construct the boats
What is "construct a prototype of a boat for testing".
A medical company designs a new device to measure a person’s vital signs, including heart rate and blood pressure. During the design process, the company produces several prototypes.
During which of the following steps is it most appropriate to use a prototype?
A. distributing information about the device
B. researching how vital signs are measured
C. testing whether the device works properly
D. determining which vital signs are most important
What is "C. Testing whether the device works properly".
True or False
Henry Ford invented the Assembly Line.
What is "false". Ransom E. Olds invented the Assembly Line.
Which of the following parts of the house should be strengthened to prevent cracks from getting worse?
The decking?
The foundation?
The roofing?
The siding?
What is "the foundation".
After which process will the data which is received make sense to the receiver?
Source?
Encoder?
Transmitter?
Decoder?
Receiver?
What is "after the decoder". The decoder take the information sent by the source and translates it back into a form that can be understood by the receiver.
Does bridge compression push forces together or push forces apart?
What is "pushes forces together". Bridge Tension pushes forces apart.
A company is designing a new laptop computer. The computer must not exceed a certain weight.
Which of the following is the most likely reason to have a weight restriction for the computer?
A.) to make it easier to test the prototype
B.) to reduce the cost of making the computer
C.) to make it easier to transport the computer
D.) to reduce the cost of building the prototype
What is "to make it easier to transport the computer".
True or False
The Assembly Line made products less expensive.
What is "true". Becasue of the Assembly Line products were able to be assembled faster.
An engineer constructs a prototype from wood. Which of the following is the best tool for the engineer to use to make the prototype’s surface smooth?
A.) band saw
B.) chisel
C.) drill
D.) sandpaper
What is "sandpaper". Sandpaper is paper covered on one side with an abrasive material (such as sand) used for smoothing things such as rough wood.
A satellite dish is an example of which of the following components of a television communications system?
A.) decoder
B.) encoder
C.) receiver
D.) transmitter
What is the "receiver". The satellite dish receives the information that is being transmitted into the home.
A computer touch screen allows users to enter information. Users have complained that the touch screen is too difficult to operate because the system does not indicate when a choice is selected.
The complaints are which part of the Universal Systems Model?
Feedback?
Goal?
Inputs?
Processes?
What is "feedback".
If a design flaw is discovered in a prototype, what is the next logical step of the design team?
What is "modify and redesign the prototype to solve the problem".
True or False
Quality Control is essential to building a successful business.
What is "true". Quality control is a procedure or set of procedures intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the client or customer.
If you were building a birdhouse to be used outside for wild birds which two materials would you choose to build it with?
Cardboard, Wood, Staples, Glue, Masking Tape
What is "wood and glue". The cardboard would fall apart outside due to weather conditions. The masking tape would weaken over time. The staples would not be strong enough to hold the birdhouse together.
A student uses a keyboard on a laptop to type a message into an instant messaging program. The processor in the laptop runs the instant messaging program's commands. The laptop uses Wi-Fi to connect to the internet. Another student reads the message on a phone.
What is the Source, Encoder, Transmitter, and Receiver?
What is:
The keyboard is the Source.
The laptop's processor is the Encoder.
The WiFi is the Transmitter.
The phone is the Receiver.
A city street must be widened. The street cannot be too close to the buildings on it.
Which of the following would best show how close the widened street would be to the buildings?
A.) floor plans of each building
B.) photographs of each building
C.) site plans of the areas in front of each building
D.) photographs of the views from the front doors of each building
What is "site plans of the areas in front of each building". Site Plans are an architectural plan, a landscape architectural document, or a detailed engineering drawing of a specific area. A Site Plan is a graphic representation of the arrangement of buildings, parking, drives, landscaping and any other structure that is part of a development project. They would be used by contractors or construction workers when making improvements or changes to a property.
