Why do engineers filter water through several different layers instead of just one?

ADifferent layers catch different sizes and types of contaminants — no single material catches everythingBExtra layers make the water flow faster through the filterCOne layer would make the water taste too cleanDFilters need to be a certain height to fit standard housings

What is FMEA?1 / 10

Failure Mode and Effects Analysis — a systematic method engineers use to find and rank the ways a product or process could fail, before it ships, so the highest-risk problems get fixed first instead of being discovered by customers.

What is a scale drawing?1 / 8

A scale drawing shows something smaller or bigger than it really is, but keeps all the proportions the same, so the shape still looks correct.

In the bracket case study, what was wrong with the original design's part count?1 / 9

It was made of 5 separate pieces — a bracket, two spacers, and two fasteners — that all had to be sourced and assembled by hand, when the same job could be done by far fewer parts.

What is friction?1 / 9

Friction is a force that resists the relative motion between two surfaces that are touching. It always acts opposite to the direction of motion, or attempted motion.

Define engineering stress σ and engineering strain ε.1 / 13

σ = F/A₀ (force over original cross-sectional area, Pa or MPa). ε = ΔL/L₀ (change in length over original length, dimensionless). These are 'engineering' values; true stress/strain use instantaneous area/length. For small deformations they are approximately equal.
