Bending occurring at the middle of the beam
is the maximum value of stress that a material can resist
τ = Tc/J
also known as second polar moment of area
the change in length along the x-axis divided by the original length
cross section of a beam or shaft along which there are no longitudinal stresses or strains.
It is the slope of initial linear part of the stress-strain curve
Orientation (θp)
σ = E* ε
Is the ratio of the stress that causes failure to the applied stress.
The ability to deform before rupture, normally characterized by a large plastic region.
Deformation
The inability to deform before rupture
Helps determine the values of moments
is a measure of the axial force acting on a beam quantitatively measuring the internal forces acting within in the beam.
Also known as 2nd moment of area
σ=P/A
Go over 2% in stress vs strain graph
commonly known as strength
For a shaft under torsional loading, the angle through which fixed end of a shaft rotates with respect to the free end
the ratio of the proportional decrease in a lateral measurement to the proportional increase in length in a sample of material that is elastically stretched.
Helps determine the value of shear force
is the elasticity coefficient for shearing or torsion force.
horizontal shear force in the middle of beam
