Mechanics of Materials Final Exam Review, 2026 – Engineering Study
and Review Material
What is Definable? - ANS✔✔ Behavior and characteristic of the materials in different conditions
and situations to be known before design begins. Also know as mechanical properties of
material.
What is Reliable material? - ANS✔✔ A reliable material must have consistent properties and be
durable enough to last its intended lifetime of application.
What is a Workable material? - ANS✔✔ A workable material must be easily shaped, handled,
fastened, connected, and so on to enable construction of various components and structures.
What is an Efficient material? - ANS✔✔ Efficiency in engineering materials can mean having
balance among requirements for criteria, for example having a balance between strength as
well as self-weight. Efficiency can also imply durability, ease of construction, and curing times.
What is Available material? - ANS✔✔ An available material is simply the convenience and ease
of acquiring.
What is Economics in material? - ANS✔✔ Factors that should be considered in the economics
include: Availability and cost of raw materials, manufacturing costs, transportation, placing, and
maintenance.
What is a Sustainable material? - ANS✔✔ Sustainable design is the philosophy of designing
physical objects, the built environment to comply with the principles of economic, social, and
ecological sustainability.
, What is strength? - ANS✔✔ Strength of a material is its ability to withstand an applied load
without failure or plastic deformation. It considers the relationship between the external loads
applied and the resulting deformation.
What is Deformation? - ANS✔✔ Deformation refers to changes of the shape or size of an object
due to applied forces or change in temperature.
What is an Elastic Behavior? - ANS✔✔ An elastic material is one that deforms immediately upon
loading, maintains constant deformation if load is held constant, and return immediately to its
original undeformed shape when load is removed.
What is Stress? - ANS✔✔ Stress is a measure of the internal resistance in a material to an
externally applied load (F/A).
What is Strain? - ANS✔✔ Strain is a measure of the deformation produced by the influence of
stress (Deformation/Original Length).
What is Poisson's Ratio? - ANS✔✔ Posson's Ratio is a measure of the amount by which a solid
"spreads out sideways" under the action of a load from above (Lateral Strain/Strain in Direction
of Load)
What is Linear Elasticity? - ANS✔✔ Linear elasticity where the relationship between stress and
strain is proportional, or linear.
What is Proportional Limit? - ANS✔✔ The max stress up to which s-e ratio is constant (linear)
What is Elastic Limit? - ANS✔✔ The max stress that can be applied to a material and still get all
strain recovered. The material returns to its original shape and/or dimensions when load is
released.
