1. REVIEW OF STRESSES
IN BEAMS

2. STRESSES IN BEAMS

3. STRESSES IN BEAMS

11. Example:
1. Determine the maximum tensile and compressive
bending stress in the beam if it is subjected to a moment
of M = 4 kip-ft.

12. 2. For the beam shown, calculate (a) the maximum
bending stress; and (b) the bending stress at a point 0.5
in. from the top of the beam on section D.

13. 3. Determine the maximum tensile and
compressive bending stress in the beam
shown.

14. SHEAR STRESS IN
BEAMS

15. Shear stress occurs when a force tends
to cause deformation to a material by
slippage along a plane or planes parallel
to the imposed stress.

SHEAR STRESS IN BEAMS

16. For equilibrium of this element, the shearing
stress on the bottom face requires an equal
balancing shearing stress on the top face. The
forces causing these shearing stresses form a
counterclockwise couple, which requires a
clockwise couple to ensure balance.
Therefore, the shearing stress acting on one
face of an element is always accompanied by
a numerically equal shearing stress acting on a
perpendicular face.

19. Examples:
1. The overhang beam is subjected to the uniform
distributed load having an intensity of w = 50 kN/m.
Determine the maximum shear stress developed
in the beam.

20. 2. Determine the maximum shear stress in the T-beam at:
(a) the critical section where the internal shear force is
maximum.
(b) at section C
