What is meant by the term 'tensile'?
Tensile refers to a force that pulls on an object to elongate or stretch it.
The opposite of tensile is compressive (squashing).

What is the formula linking tensile stress, tensile force (F), and area (A)?
tensile stress (Nm-2)
F = tensile force (N)
A = cross-sectional area (m2)

What is the formula linking tensile stress (σ), tensile force (F), and area (A)?
σ = tensile stress (Nm-2)
F = tensile force (N)
A = cross-sectional area (m2)

What is 'ultimate tensile strength'?
The maximum stress a material can experience before breaking.
Answer in your head, out loud, or on paper, then tap the card to flip.
What does a higher Young's modulus mean?
The material is stiffer as it requires more stress to produce a given strain.
