Material Testing
This test applies a uniaxial tension force to a dog-bone shaped sample until failure.
What is a tensile test?
This recycling symbol identifies the resin content of plastic products.
What is the recycling resin code?
This process forms parts by pouring molten material into a mold and allowing it to solidify.
What is casting?
This type of quantity has magnitude only, such as mass or temperature.
What is a scalar quantity?
This structural element is commonly supported with one pin support and one roller support.
What is a simply supported beam?
This quantity is calculated by dividing applied force by the original cross-sectional area of a specimen.
What is stress?
These material categories include metals, polymers, ceramics, organics, and composites.
What are material classes / categories?
This machining process creates cylindrical parts by rotating the workpiece against a cutting tool.
What is turning?
This vector quantity describes a push or pull with magnitude, direction, and point of application.
What is a force?
This condition determines whether a truss can be solved using equilibrium equations alone.
What is static determinacy?
This term describes the amount of stretch per unit length in a material under load.
What is strain?
This type of material is composed of more than one material to achieve desirable combined properties.
What are composite materials?
This plastic manufacturing method forces molten material into a closed mold under pressure.
What is injection molding?
This condition occurs when the sum of all forces acting on a body equals zero.
What is translational equilibrium?
This property measures how a cross-sectional area resists bending and depends on geometry.
What is moment of inertia?
This region of the stress–strain curve represents recoverable deformation where stress and strain are proportional.
What is the elastic range?
These materials are mostly carbon-based, renewable, and were once living organisms.
What are organic materials?
This additive manufacturing process produces parts directly from CAD models layer by layer.
What is rapid prototyping (3D printing)?
This principle states that for every action force, there is an equal and opposite reaction force.
What is Newton’s Third Law?
This material property describes resistance to elastic deformation and is a material constant.
What is modulus of elasticity?
This material property represents the total area under the stress–strain curve up to fracture and includes strength and ductility.
What is toughness?
This polymer subgroup can be repeatedly heated and remolded without changing chemical structure.
What is a thermoplastic?
This controlled heating and cooling process alters material properties without changing shape.
What is heat treating?
This diagram isolates an object and shows all external forces acting upon it.
What is a free body diagram?
This point represents the center of gravity of an object and is used in statics calculations.
What is the centroid?
