What is the first step in analyzing a beam?
Think about forces acting on the beam.
Define shear force.
Consider its effect on the beams layers.
What is the first step in analyzing internal forces on a beam?
Think about equilibrium.
True or False: The bending moment can be found by summing moments about a section from external forces.
Consider how moments work.
A simply supported beam carries a uniform load of 10 kN/m over a length of 8 meters. Calculate the support reactions and verify by decomposing the beam.
Total load can be used to find reaction at supports.
For a cantilever beam of length 5m with a point load of 15kN at the free end, determine the internal shear and bending moment at 2m from the fixed end.
Draw a free body diagram to visualize forces.
