Shear Force Next to a Midspan Load
Easyshearpoint load
A simply supported beam carries a single 20 kN downward point load at midspan. Neglect self-weight. What is the shear force magnitude immediately to the left of the load?
- A0 kN
- B5 kN
- C10 kN
- D20 kN
Show solutionHide solution
Answer: C. 10 kN
Each support reaction is 20/2 = 10 kN upward. There are no other loads between the left support and midspan, so the shear magnitude just left of the point load is 10 kN.
