5 cards from this section. Quick, good the night before a test.
Define axial force.
Think about forces related to stretching or compressing a beam.
What is the first step in calculating support reactions?
Consider the conditions for balance in structures.
What do you need to analyze first when studying internal forces in beams?
Think about beginning your calculations with equilibrium in mind.
True or False: A bending moment increases the angle of deflection of a beam.
Visualize how a beam behaves under load.
A beam is subjected to two point loads at different distances from the support. Calculate the shear, moment, and axial force at the midpoint.
Analyze the forces acting up to the midpoint carefully.
Given a cantilever beam with a distributed load, find the maximum bending moment and where it occurs.
Remember, the maximum bending moment usually occurs where the load effects are greatest.
