M1 Flashcards
Forces that act in a single plane; thus, the forces are parallel to the plane and their points of application are in
the plane.
Coplanar
The ratio of strain to the original
length.
Strain
The frictional forces depend on the
coefficient of friction and this______.
Normal Force
A type of stress that acts coplanar
with a cross section of material.
Shearing stress
What is the derivative of the shear
equation of a beam?
Load
The ability of the material to resist deformation under stress.
Stiffness
The ratio of unit lateral deformation
to unit longitudinal deformation.
Poisson’s ratio
The maximum load that a material
can support without fracture when being stretched, divided by the original cross-sectional area of the
material.
Tensile strength
A mechanical property of metal that
is the degree to which a material may be bent, stretched, or compressed before it ruptures.
Elongation
The ratio of stress to strain within the
elastic limit.
Modulus of elasticity
The ability of a material to resist
being crushed.
Compressive strength
The total resistance that a material
offers an applied load.
Stress
The ratio of the ultimate stress with
the allowable stress.
Factor of safety
A simple term for force.
Push or Pull
The greatest unit pressure the soil can continuously withstand.
Bearing strength
