Engineering and Design - Unit 3: Quiz 2. Sketch modeling

1. a sketch line that connects a comment to the location of the corresponding object with a thin line. 2. a thin sketch line with arrowheads on each end that is broken in the middle to allow the placement of the dimensional value. 3. a line that represents the contour of an object and the parts of the object that are visible to viewers.

1. leader line 2. dimension line 3. object line

1. Three-dimensional, solid geometric objects with multiple polygonal sides or faces. 2.The study of the outward appearance or beauty of an object. 3.A depiction of an engineering design that allows others to see the engineer's idea.

1. polyhedra 2. aesthetics 3. model

1. A machinist is unable to create a prototype using the technical sketches he was given by the engineer. The pieces are not matching up correctly. 2. Zachary needs to create a model for his design in the early phases of his design creation. He knows there will be many changes as the project progresses. 3. Beth needs to calculate the dimensions of her model. It will need to be much smaller than the final product.

1. proportion 2. sketch 3. ratio

1. the ratio between the dimensions of an object and the dimensions of the model or drawing of the object. 2. an object's length, width, measurement, and location in space. 3.an engineering drawing that provides details of an object's design.

1. scale 2. dimension 3. sketch

1. As an engineer designs a new truck, he creates a model that has its sides unfolded so the client is able to see the front view through the center of the drawing. 2. Kelly has just completed a drawing of a model that allows the client to see the product in three dimensions with every axial view visible. This allows the client to envision the entire product. 3. John has been working on the design for a new video recorder. At this point he just needs to show the client a sketch of the recorder from the front so that all the functional buttons are visible.

1. third-angle projection 2. isometric projection 3. orthographic projection

Which option best defines aesthetics?

Aesthetics refers to the study of the outward appearance or beauty of an object.

Which of the following explains why modeling the unpredictable is so important?

Engineers must be able to determine appropriate changes that could lead to the survival of thousands of people.

________ engineers design and improve the production process by identifying sources of waste and inefficiency.

Industrial

Which of the following explains why it may be difficult to test a larger system?

Only new design components can be replicated, which makes reliable testing an issue.

Which of the following represents how engineers are helping to reduce the risk of human injuries with their designs?

Remote-controlled robots are sent into fires with mechanized cannons that can shoot water to distances of one hundred fifty feet.

In no less than one hundred fifty words, explain three reasons why an engineer would choose to use a prototype as his or her model on a design project.

The first reason why an engineer would choose to use a prototype as his or her model on a design project is that prototypes help engineers can test out their product mobility and if it functions as described. The second reason why an engineer would choose to use a prototype as his or her model on a design project is that prototypes can show the employer and the engineer how aesthetically pleasing the prototype will be. The third reason why an engineer would choose to use a prototype as his or her model on a design project is that prototypes allow the engineers to test their product against certain weather conditions or any circumstances that may affect it. Those are the best reasons as to why an engineer would choose to use a prototype as his or her model on a design project versus any other models that could be used by the engineer.

Which option explains why a prototype is necessary before committing to a purchase in the following scenario? Tyler is developing a robot that can be sent into war zones to ensure that any mines have been detonated before soldiers are sent into the area. The government is requiring a full-scale model of this robot before it is willing to purchase one.

The vehicle might be very expensive.

Which of the following explains how students access basic sketch translation programs?

They can download many software programs for free.

Which option identifies what Sean should choose to assist in his design in the following scenario? Sean is an aerospace engineer who has just been hired to design a cooling system for a large jet airplane. The design will require multiple prototypes, but the client is not willing to fund them.

a computer program to simulate the cooling system

Which type of engineer would lead a team in trying to mine valuable metals from a passing asteroid?

Which of the following degrees is needed to become a geological engineer?

bachelor's degree in mining engineering

While ________ simulations will not be able to demonstrate the weight and feel of a final product, they still provide valuable information by breaking it down into components clients can see.

computer

Which of the following fields allows individuals to explore their creativity and ingenuity by devising new ways to think about everyday objects?

Which of the following is described as a way engineers can test and investigate how things should be under certain circumstances?

prescription

In order for an engineer to diagram a model to the correct __________ , use of a straightedge is essential to assist with measurement and drawing straight lines.

Which option identifies the type of model to develop in the next stage of the process in the following scenario? Christopher needs to deliver a model of his new solar-powered cell phone charger to his client. He is still working on the design and is not ready to create a prototype since that would require too much time and money.
