3 cards from this section. Quick, good the night before a test.
Define eccentric loading.
Think about what happens when the load isn't centered.
What is the formula for total stress under eccentric loading?
What are the main components of the stress formula?
What causes bending stresses in a column?
Remember the definition of eccentric loading.
True or False: Total stress in a column under eccentric loading is solely due to axial load.
Think about the different stress components involved.
A column has an effective length of 4 m and is subject to an axial load of 30 kN applied 0.3 m off-center. Calculate the total stress at the top and bottom surfaces, with a moment of inertia of 0.0015 m^4.
Ensure you correctly apply the formula for calculating stress considering eccentricity.
If a column is designed to support loading of 100 kN at an eccentricity of 0.2 m, evaluate how this loading condition affects its design considerations and explain why correct material choice and geometry are crucial.
Consider the importance of balancing both axial and bending stresses in your reasoning.
