3 cards from this section. Quick, good the night before a test.
Define bending energy in your own words.
Think about how beams store energy under loads.
What formula relates stress to bending moment?
Focus on the relationships between forces and geometry.
What is the primary factor affecting bending energy in a beam?
Think about what causes beams to store energy in bending.
True or False: The curvature of a beam increases with higher bending moments.
Consider how loads affect the geometry of beams.
A simply supported beam with a point load at its center stores how much energy when it bends? Calculate using appropriate bending moment and curvature relations.
Use the load to determine the maximum moment and apply it to the energy equation.
Given a beam with varying cross-section, derive the general expression for bending energy considering the moment of inertia's variation.
Reflect on how integration over varying cross-sections influences overall energy.
