A beam of length 5 m has a shear force variation given by V(x) = 10 - 2x2 kN at a distance x from one end. It is observed that the bending moment at x = 1 m is 6 kN-m. What is the location of the point of contraflexure in the beam from that end? (Neglect the sign/direction of the bending moment.)
- 19.35 m
- 20.325 m
- 31.5 m✓
- 40.65 m
Correct answer
1.5 m
