2 cards from this section. Quick, good the night before a test.
Define non-uniform bending.
Think about what happens to the bending moment.
What is the relationship between bending moment and curvature?
Recall the formula we discussed.
What happens to shear force when the bending moment is non-constant?
Think about what varying moments imply.
True or False: An I-beam experiences the same shear stresses throughout its length.
Consider how loads affect different points along the beam.
Given a cantilever beam with a point load of 100 N at the free end and length 2 m, calculate the shear stress at a section 0.5 m from the fixed end.
Use the bending moment equation first to derive V.
Analyze a simply supported beam with a varying distributed load. Derive the equations for stress distribution at various sections.
Remember to balance forces and moments at each section.
