Testing the prototype
Defining the problem
Building a model
Evaluating solutions
What is a key characteristic of the iterative design process?
It is a linear process with no feedback loops
It involves repeating steps to refine and improve the design
It requires only one prototype
It is completed in a single phase
Which of the following is a method to evaluate design solutions?
Brainstorming
Prototyping and testing
Sketching ideas
Conducting interviews
How does identifying design constraints influence the design process?
It limits creativity and innovation
It helps focus the design efforts on feasible solutions
It increases the complexity of the project
It eliminates the need for testing
Which step in the engineering design process involves generating multiple ideas to solve a problem?
Mind mapping

The earliest bridges were made of stone.
True
False
What was the most significant innovation in bridge engineering in the late 18th century?
The use of iron
The development of the truss bridge
The use of pneumatic caissons
The development of the cantilever bridge
What type of bridge is used extensively for railroad bridges?
What are the two types of loads that engineers consider when designing a bridge?
Live load
Compression load
Dead load
Tension Load
What are some environmental factors that can affect a bridge?
The efficiency of a model truss bridge is determined by the:
Failure mass divided by the mass of the structure.
The weight of the load divided by the number of supports.
The length of the bridge divided by the number of members.
The total cost of materials divided by the number of members.
Match the definition with the type of bridge
A type bridge having a curved structure. The design provides strength by exerting force downwards and sideways against the abutments.
arch bridge
A type of bridge in which the deck hangs from wires attached to thick cables. The cables themselves pass over towers and are securely anchored in concrete anchorages
suspension bridge
A type of beam bridge, reinforced by a framework of girders that form triangular shapes.
truss bridge
A type of bridge that connects the crossbeam or bridge deck directly to pillars or towers
cable-stayed bridge
A type of bridge uses a pillar anchored vertically into the ground to support a horizontal deck extending out from one or both sides across the span.
cantilever bridge
The stone arch bridge design is among the strongest and most durable. In stone arch bridges, the stones are in ________ (pressing against each other).
A) tension
B) compression
C) suspension
D) expansion
Suspension bridges are supported by steel cables under tension, which hold up the _______.
Roadbed
Towers
Deck
Piers
A characteristic of a simple truss bridge is (a)
What is the span of a bridge?
A truss is designed to be much stronger than a four-sided figure. Which shape is commonly used in truss design?
Square
Rectangle
Triangle
Circle

There's something you spent time studying that wasn't on the exam. What is it and how does it work? Explain.
You are designing a robotic gripper for a manufacturing assembly line. The gripper must be able to handle a variety of delicate electronic components without damaging them.
Explain how the iterative design process would be crucial in refining the gripper's design to ensure it meets the requirements for handling delicate components.
