Max Moment, Simple Beam with Uniform Load
Easybending momentuniform load
A simply supported beam carries a uniformly distributed load w = 10 kN/m over its full span L = 4 m. What is the maximum bending moment magnitude?
- A10 kN·m
- B20 kN·m
- C40 kN·m
- D80 kN·m
Show solutionHide solution
Answer: B. 20 kN·m
For a full-span uniform load, maximum bending moment occurs at midspan: Mmax = wL²/8 = 10(4²)/8 = 20 kN·m.
