3 cards from this section. Quick, good the night before a test.
Define axial force and provide an example.
Think of forces that are directed along the same line as the beam.
What do we measure when determining support reactions?
These forces ensure equilibrium on the structure.
What is the first step in analyzing a beam?
Think about the order of operations in beam analysis.
True or False: The shear force at a point is affected by the load distribution along the beam.
Recall how loads influence internal forces.
A cantilever beam of length 5m is carrying a uniform distributed load of 800 N/m. Calculate the maximum bending moment at the fixed support and plot shear and bending moment diagrams.
Understand how the uniform load influences the beam throughout its length.
Given a simply supported beam with a length of 6m, a centralized load of 12kN, and an additional 3kN at 1m from the left support, calculate the shear force just left of the 12kN load and then right of it.
Use equilibrium equations to find reactions before analyzing shear.
