Engineering 1 Sem 2 Final

A biomedical engineering company makes replacement body parts and organs. The company wants to redesign an organ so that it can be reused in more than one place in the human body.

After the company thinks of ideas, what is the next step in the design process?

• Build a prototype

• Define the problem

• Decide on the best solution

Which of the following materials was commonly used to construct the frame of a medieval trebuchet?

• Wood

• Brick

• Stone

• Iron

What is the principle of conservation of momentum?

• The total velocity of a closed system remains constant unless acted upon by an external force.

• The total mass of a closed system remains constant unless acted upon by an external force.

• The total energy of a closed system remains constant unless acted upon by an external force.

• The total momentum of a closed system remains constant unless acted upon by an external force.

Why is it important for engineers to maintain an engineering notebook?

• It is important for engineers to maintain an engineering notebook to keep track of their favorite recipes.

• It is important for engineers to maintain an engineering notebook to document their travel experiences.

• It is important for engineers to maintain an engineering notebook to record their design process, observations, experiments, and innovative ideas, ensuring intellectual property protection and efficient project management.

• It is important for engineers to maintain an engineering notebook to write down their daily schedule and appointments.

In a design review meeting, Noah, Sophia, and Mia are discussing various engineering drawing techniques. Noah proposes the use of isometric projections. What could be the potential advantages of Noah's suggestion?

• Isometric projections provide a simple and effective way to represent three-dimensional objects in two dimensions, making it easier for engineers to visualize and understand the design.

• Isometric projections are more complex than other types of engineering drawings and require specialized software to create.

• Isometric projections do not accurately represent an object's dimensions and shape, making it difficult for engineers to analyze and interpret.

• Isometric projections only provide a two-dimensional view of an object, making it challenging to visualize the design in three dimensions.

Convert 3 liters to gallons.

• 0.792516

• 1.792516

• 2.792516

• 3.792516

If the resistance in a circuit is doubled while the voltage remains constant, what happens to the current according to Ohm's Law?

• The current is halved.

• The current doubles.

• The current remains the same.

• The current becomes zero.

Which word best describes a constraint?

• option
• opportunity
• limitation
• goal

An engineer suggests using a robotic system to manufacture a particular chemical. Which of the following is most likely the engineer’s reason for making the suggestion?

• reducing the cost of materials

• reducing workers' exposure to chemicals

• increasing the cost of production

What is the primary advantage of using 3D printing in manufacturing?

• It reduces the need for skilled labor in the production process.

• It allows for mass production of identical items.

• It is the fastest method for producing large quantities of products.

• It enables the creation of complex and customized designs with minimal waste.
