What are the key principles of the NCEES Model Law?

A

Key principles focus on promoting ethical practices and safeguarding public health, safety, and welfare in engineering.

29
Q

A

Ensuring that engineering projects do not adversely affect the health of the public and comply with safety regulations.

33
Q

Define copyright in the context of intellectual property.

A

A legal right granted to the creator of original works of authorship including literary, dramatic, musical, and certain other intellectual works.

34
Q

What is a trade secret and how is it protected?

A

Information that is not generally known and is subject to reasonable steps to maintain its secrecy. Protection involves non-disclosure agreements and security measures.

A

Trademarks protect symbols, names, and slogans used to identify goods or services; significant for branding and legal protection against infringement.

37
Q

What is life-cycle analysis and its application?

A

A technique to assess environmental impacts associated with all stages of a product’s life, used for improving sustainability.

38
Q

What is the principle of financial equivalence?

A

The concept that different sums of money at different times can be equivalent in economic value when considering interest rates or inflation.

39
Q

How is present worth calculated?

A

By discounting future cash flows to the present using a discount rate, reflecting the time value of money.

40
Q

What differentiates fixed and variable costs?

A

Fixed costs do not change with production levels, whereas variable costs vary directly with the level of production.

41
Q

What is break-even analysis?

A

A calculation to determine the point at which revenue received equals the costs associated with producing the revenue.

42
Q

What is the significance of overhead considerations in project costing?

A

Overhead costs, which are not directly tied to production levels, need to be accurately allocated to understand the total cost of a project.

43
Q

A

Charge is a property of matter that causes it to experience a force when near other electrically charged matter.

44
Q

How does Ohm’s law define the relationship in a circuit?

A

Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

45
Q

What is the role of capacitors in AC circuits?

A

Capacitors store electrical energy temporarily and affect the phase and amplitude of AC signals.

46
Q

What is the purpose of Kirchhoff’s laws in circuit analysis?

A

Kirchhoff’s laws address the conservation of charge and energy in electrical circuits, helping analyze complex networks.

47
Q

How do series and parallel circuits differ?

A

In series circuits, components are connected end-to-end, so the same current flows through each; in parallel circuits, components are connected across the same voltage, allowing separate current paths.

Q

What are the types of annuities in financial calculations?

A

Includes ordinary (payments at end of periods) and annuities due (payments at beginning of periods).

49
Q

50
Q

Explain the concept of incremental cost.

A

The additional cost associated with producing one additional unit of output.

51
Q

How are sunk costs relevant in economic decision-making?

A

Sunk costs are costs that have already been incurred and should not be considered in making future economic decisions.

52
Q

Define the economic and environmental perspectives of life cycle analysis.

A

Economic perspective focuses on cost over a product’s lifespan, while environmental perspective assesses the ecological impact during the same period.

53
Q

What are DC motors and how do they differ from AC motors?

A

DC motors allow for variable speed control and have a simpler design, whereas AC motors are powered by alternating current and are typically used for constant speed operations.

54
