Elements: Beams and Bending
Beams and Bending
What could be simpler?
- All beams involve bending: tension and compression stresses
working on opposite edges of the beam to form a couple.
- This action deforms each small rectangular slice of a beam into a wedge
shape that is narrower on the compression side and wider on the tension
- By studying this deformation and relating it to mechanics of materials,
we can establish a relationship between the internal moment, the
stress in the beam, and the cross section properties.
- This relationship is critical to understanding the proper form and proportioning
