Engineering Concepts Quiz

Which term refers to the study of the motion of air and how it interacts with solid objects such as an airplane wing or a car?

• Balancing

• Aerodynamics

• Analysis

• Energy Efficiency

What is the term for the point where the distribution of weight is equal so that the car remains stable?

• Center of Mass

• Compliance

• Data Collection

• Material Selection

Which term describes the concept of reducing the force that resists the movement of a car?

• Friction Reduction

• Energy Efficiency

• Power-to-Weight Ratio

• Material Selection

What is the term for the set of fundamental concepts or assumptions that guide engineering design and practice?

• Rules

• Principles

• Regulations

• Testing

Name the law that explains how CO2 dragsters are propelled.

• Law of Conservation of Energy

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

Explain what happens when you puncture a CO2 canister?

• The canister will implode

• The gas will remain inside the canister

• The gas will escape rapidly, propelling the canister

• The canister will expand

Define the term Inertia.

• The force that keeps an object at rest or in uniform motion in a straight line

• The resistance of any physical object to a change in its state of motion

• The tendency of objects to keep moving in a straight line at constant velocity

• The force required to move an object from rest

What is Newton's Third Law of Motion? And how is the propulsion of CO2 cars explained?

• For every action, there is an equal and opposite reaction; the gas escaping the canister pushes the car forward

• The acceleration of an object is directly proportional to the net force acting on it; the gas provides the force to move the car

• An object at rest stays at rest and an object in motion stays in motion; the car moves due to the initial force of the gas

• The rate of change of momentum of an object is proportional to the applied force; the gas escaping causes a change in momentum

Explain what is the difference between skin and fluid friction?

• Skin friction is due to air resistance, while fluid friction is due to water resistance

• Skin friction is due to contact with solid surfaces, while fluid friction occurs in liquids and gases

• Skin friction is a type of static friction, while fluid friction is a type of kinetic friction

• Skin friction and fluid friction are the same

How do you determine the speed of the CO2 dragster?

• By measuring the time it takes to travel a certain distance

• By calculating the force exerted by the CO2 gas

• By the weight of the CO2 canister

• By the size of the CO2 canister
