What is the definition of shear?
Think about forces that slide one layer of material over another.
What does a moment diagram represent?
Consider how bending works in beams.
What does a positive moment cause in a beam's fibers?
Remember the basic effect of bending.
True or False: The slope of a shear diagram at a point is equal to the load intensity at that point.
Think about how forces influence shear.
A uniform load of 500 N/m is applied on a simply supported beam of 6m span. Calculate the shear and moment at 2m from the left support.
Use equilibrium to find reactions before applying them to the shear and moment calculations.
For a cantilever beam of length 5m with a point load of 2000N at the free end, draw the shear and moment diagrams.
Consider how the point load impacts the beam.
