Question 1

The study of the laws of nature is&#10;A) science&#10;B) engineering&#10;C) forensics&#10;D) crime analysis

Accepted Answer

The study of the laws of nature falls under the branch of knowledge called science. Engineering is the application of scientific principles to design and build structures, machines, and other devices. Forensics is the application of scientific methods to solve crimes, while crime analysis involves using data to identify patterns and trends related to criminal behavior.

Question 2

A person who uses the laws of nature to design devices to improve mankind is called a (an)&#10;A) scientist&#10;B) engineer&#10;C) crime scene investigator&#10;D) designer

Accepted Answer

An engineer is someone who uses the laws of nature to design devices and systems that improve society, such as bridges, airplanes, and communication networks. Scientists may conduct research to understand the laws of nature, but engineers use this knowledge to create practical solutions to real-world problems. Crime scene investigators and designers may have skills that overlap with engineering, but they do not specifically use the laws of nature to design devices for the betterment of society.

Question 3

The study of matter and energy and how they interplay in the universe is called&#10;A) engineering&#10;B) science&#10;C) physics&#10;D) forensics

Accepted Answer

The study of matter and energy is the primary focus of physics, making option C the correct answer. Engineering may involve physics concepts, but it is primarily focused on designing and building practical systems. Science is a broad term that encompasses many different fields, including physics, but it is not specific enough to be the correct answer in this context. Forensics is the application of scientific techniques to criminal investigations, but it is not a primary focus of the study of matter and energy.

Question 4

Engineering of amazing structures has had roots dating back as far as&#10;A) 1900's&#10;B) 1000 A. D.&#10;C) 1800's&#10;D) 2600 B. C.

Accepted Answer

Some of the earliest structures, such as the ancient pyramids in Egypt, were engineered as far back as 2600 B.C.

Question 5

Forensic engineering differs from other engineering in that it deals with&#10;A) the aftermath of design&#10;B) the aftermath of failure&#10;C) the design of forensic devices&#10;D) the design of crime scenes

Accepted Answer

Forensic engineering deals with investigating and analyzing failures in structures, systems, or components. It involves determining the cause of failure and providing recommendations to prevent similar failures from occurring in the future. It is not related to the design of forensic devices or crime scenes, nor does it primarily deal with the aftermath of design.

Question 6

Devices that fail due to design or manufacturing flaws have defects that are called&#10;A) primary defects&#10;B) secondary defects&#10;C) tertiary defects&#10;D) engineering defects

Accepted Answer

primary defects refer to defects that occur due to design or manufacturing flaws. They are the initial defects that cause the product to fail. Secondary defects are defects that occur as a result of primary defects, while tertiary defects occur due to wear and tear or external factors. Engineering defects is not a commonly used term in this context.

Question 7

Devices that fail after use by the consumer have defects that are called&#10;A) primary defects&#10;B) secondary defects&#10;C) tertiary defects&#10;D) engineering defects

Accepted Answer

Devices that fail after use by the consumer have defects that are called secondary defects. Primary defects are those that are present at the point of sale, while tertiary defects are those that do not affect the safety or function of the device. Engineering defects refer to flaws in the design or construction of the device.

Question 8

The two types of individuals who investigate vehicle collisions are&#10;A) forensic engineer, crime scene technician&#10;B) engineer, accident reconstructionist&#10;C) accident reconstructionist, forensic engineer&#10;D) engineer, police officer

Accepted Answer

The two types of individuals who investigate vehicle collisions are accident reconstructionists and forensic engineers. A forensic engineer may be involved in the investigation to assess the condition of the vehicle or the road at the time of the collision, while an accident reconstructionist uses physical evidence and data to recreate the scene and determine the cause of the collision. Therefore, choice C is the correct answer.

Question 9

Some of the concepts of physics used in accident investigation are&#10;A) Newton's Laws and light&#10;B) Newton's Laws and electricity&#10;C) Light and electricity&#10;D) Newton's Laws and momentum conservation

Accepted Answer

Newton's Laws and momentum conservation are the most important concepts in accident investigation as they can provide valuable insights into the cause and nature of the accident. Newton's Laws explain the motion of objects before, during, and after an accident, and momentum conservation explains how the forces acting on objects in an accident affect their movement and direction.

Question 10

A car headlight that exhibits hot shock tells the investigator&#10;A) the headlight was broken&#10;B) the headlight was on during the accident&#10;C) the headlight was off during the accident&#10;D) the headlight was defective

Accepted Answer

Hot shock occurs when a headlight is on during an accident and then suddenly impacted. The hot bulb's filament creates a distinctive pattern on the surrounding glass, indicating it was on before the crash.
