3 cards from this section. Quick, good the night before a test.
What does P represent in the total stress equation?
It is the force acting along the length of the column.
Define eccentric loading in terms of structural columns.
Think about where the load is applied in relation to the center of the column.
What does the total stress equation account for?
Recall the components of the stress equation.
True or False: Eccentric loading only influences axial stress.
Consider what eccentricity adds to the analysis.
A column that is 3m tall has a moment of inertia of 0.0003 m⁴ and an applied load of 15,000 N with a 0.2 m eccentricity. Calculate the total stress in the column.
Remember to find A using the total height and assume a circular cross-section.
Discuss the implications of not considering eccentric loading in a column design. What could happen?
Consider real-life structural failures and their causes.
