FE Industrial and Systems Human Factors, Ergonomics, and Safety Practice Problems

The current FE Industrial and Systems specification assigns 8-12 of the 110 exam questions to Human Factors, Ergonomics, and Safety. Form A contains 8 original problems in this area. The sample below is published in full, with the same worked-solution format used throughout the book.

Free sample problem

A worker lifts a 160 N load with horizontal moment arm 0.35 m about the lower back. Load moment is most nearly:

  1. (A)14 N m
  2. (B)28 N m
  3. (C)42 N m
  4. (D)56 N m
Show worked solution

Answer: (D)

Force times perpendicular distance gives 56 N m.

Exposure, force, or human-performance quantities are kept on a common basis.

Substitution and unit reduction give the reported value.

Why the other choices appear

  • (A)This introduces an extra factor of 0.25 that is not present in the governing relation.
  • (B)This value is 50% below the verified result; no stated conversion creates that change.
  • (C)The units are retained, but an unsupported 0.75 multiplier changes the requested magnitude.

The complete FE Industrial and Systems practice exam contains 8 problems in this area and 110 problems overall, with an answer key, full solutions, and a score sheet by knowledge area.
