Challenge Problems
Push your limits with advanced challenges
A simply supported beam with a length of 20 ft is subjected to a uniformly distributed load of 3 k/ft. Calculate the maximum moment and shear at midspan.
💡 Hint: Use the moment equation and consider the location of maximum values.
For a beam with a triangular load distribution peaking at 4 k/ft over a length of 10 ft, derive the expressions for the shear and moment.
💡 Hint: Consider how load changes shape and the effect on internal forces.
