Concept of Stress and Strain –cont.
• Last class
– Definition of stress
• Normal stress
• Shearing stress
• Bearing stress
– Always useful to draw FBD (statics)
Stress in Two Force Members
Axial forces on a two force member
result in only
normal stresses
on a
plane cut
perpendicular
to the
member axis.
Transverse forces on bolts and pins >
only shear stresses on the plane
perpendicular to bolt or pin axis.
either axial or transverse forces
may produce
both normal and shear
stresses
with respect to a plane other than one cut perpendicular to the
member axis.
