Material Fatigue Quiz #2 - Fastest Finger First

The material with the highest ultimate tensile strength is:

• Cast Iron

• Bone

• Aluminium

• Human Hair

The correct engineering definition of 'fatigue' is:

• Weariness or exhaustion from labour, exertion, or stress

• Transient, Cumulative, and Circadian

• The weakening of a material caused by cyclic loading

• Physical or mental weariness resulting from effort or activity

Measured material property data can have scatter within the results. Tick all of the reasons below that you think can cause scatter.

• Material Structure

• Production or Manufacture

• Loading and Stresses

• Environmental Conditions

What do you think the term 'endurance limit' means in Engineering?

• The stress below which a material can endure an infinite number of repeated load cycles

• The ability to resist, withstand, recover from, and have immunity to trauma, wounds, or fatigue.

• The capacity of something to last or to withstand wear and tear.

• Denoting or relating to a race or other sporting event that takes place over a long distance or otherwise demands great physical stamina.
