PAE Fall Final Review - 12/16/24

What defines an open system in engineering?

• A system that exchanges energy and matter with its surroundings

• A system isolated from all external influences

• A system that exchanges only energy

• A system that does not interact with its environment

Why is it important to understand closed systems in engineering?

• To optimize energy flow in isolated systems

• To design systems that never lose mass but exchange energy

• To create systems that operate independently

• To avoid interactions with the environment

Which engineering innovation accelerated industrial growth during the 19th century?

• Steam engines

• Solar panels

• Internet technology

• Electric circuits

What is a key component of technological systems?

• Input, process, output, and feedback

• Design, testing, and evaluation

• Machines, energy, and money

• Software and hardware only

How does IoT (Internet of Things) enhance modern systems?

• By eliminating manual control

• By enabling communication among connected devices

• By simplifying non-automated operations

• By replacing wireless networks

What is the primary function of feedback in a system?

• To adjust and improve processes

• To identify resources required

Which of the following best describes the role of sensors in manufacturing?

• Enhancing system inefficiencies

• Detecting anomalies and triggering adjustments

• Storing energy for future use

• Replacing all human oversight

Why is PPE (Personal Protective Equipment) critical in the workplace?

• To improve work aesthetics

• To protect individuals from workplace hazards

• To eliminate safety training

• To reduce costs of materials

What is the first step in the engineering design process?

• Defining the problem

• Building a prototype

• Selecting materials

• Testing final outputs

What happens during the evaluation phase of design?

• The prototype undergoes rigorous testing for improvements

• The process skips adjustment steps

• Solutions are finalized without testing

• New solutions are avoided to save time
