Question 1

In engineering risk analysis, risk is typically defined as:

Accepted Answer

The product of probability of occurrence and consequence severity

Answer

Risk = Probability × Consequence; this formulation allows quantitative comparison of hazards with different likelihoods and impacts.

Question 2

Noise pollution is typically measured in decibels (dB), which is a:

Accepted Answer

Logarithmic scale of sound pressure level relative to a reference

Answer

SPL (dB) = 20 log₁₀(p/p_ref), where p_ref = 20 μPa; the logarithmic scale reflects the ear's response to sound across many orders of magnitude.

Question 3

ISO 14001 is an international standard for:

Accepted Answer

Environmental management systems

Answer

ISO 14001 specifies requirements for an Environmental Management System (EMS) to help organizations minimize environmental impact and comply with regulations.

Question 4

The concept of 'carrying capacity' in environmental systems engineering refers to:

Accepted Answer

Maximum population or load an ecosystem can sustainably support

Answer

Carrying capacity is the maximum population size (or resource use level) that an environment can sustain indefinitely without degradation.

Question 5

Design for Disassembly (DfD) in sustainable engineering focuses on:

Accepted Answer

Enabling easy separation of components for recycling or reuse at end of life

Answer

DfD principles facilitate efficient disassembly at end-of-life, allowing materials recovery and reuse, supporting circular economy goals.
