SHEAR STRESS IN BEAM
Shear Stress in Beams
• Shear stress refers to the stress distribution across the cross section of a
beam due to applied loads. It can be influenced by factors such as the load
distribution, beam material, and support conditions.
• Various factors such as the material of the beam, support conditions, load
distribution, and the shape and size of the beam influence the magnitude
and distribution of shear stress.
• Shear stress in the beams is widely applied in sectors like construction,
automotive and aerospace engineering, material science, architecture, and
transportation systems.
• Bending and shear stresses experienced by beams under load, but they
differ in generation and impact. Bending stresses is developed due to the
applied bending moment, while shear stress results from load distribution
across a beam’s cross-section.
SHEAR STRESS
FORMULA (HORIZONTAL SHEAR)
The distance e is defined as the distance from the neutral axis to
the point of maximum shear stress. The shear force V is normal
to the NA and it acts along the vertical axis of symmetry, hence
through the shear center. The maximum shear stress is given in
terms of the ratio V/A.
