Which engineering ethics principle requires engineers to hold paramount the safety, health, and welfare of the public?
Answer: Public safety priority
The NSPE Code of Ethics mandates that engineers hold paramount the safety, health, and welfare of the public above all other obligations.
What is the purpose of a Wheatstone bridge circuit in measurement systems?
Answer: Measure unknown resistance with high precision
A Wheatstone bridge uses four resistors in a bridge configuration to measure an unknown resistance by balancing the bridge to achieve zero galvanometer deflection.
In computer-aided design (CAD), what does a Boolean subtraction operation produce?
Answer: One solid with material removed where another solid intersects
Boolean subtraction removes the volume of one solid from another, useful for creating holes, slots, and cutouts in 3D models.
Which soil property is defined as the ratio of void volume to total soil volume?
Answer: Porosity
Porosity (n) is the ratio of void volume to total volume (n = Vv/V), while void ratio (e) relates void volume to solid volume.
In a pressure vessel, hoop (circumferential) stress for a thin-walled cylinder under internal pressure p with radius r and wall thickness t is:
Answer: pr/t
Hoop stress in a thin-walled cylinder is σ_θ = pr/t, which is twice the longitudinal stress and governs the design against bursting.
Which algorithm is commonly used in network analysis for finding the shortest path between two nodes?
Answer: Dijkstra's algorithm
Dijkstra's algorithm finds the minimum-cost path in a weighted graph by iteratively selecting the unvisited node with the smallest known distance.
In engineering project management, the critical path is defined as:
Answer: The longest duration path through the project network
The critical path is the longest sequence of dependent tasks in the project network, and any delay on it directly extends the project completion time.
