Resultant Location of Parallel Forces
Easyresultantsmoments
Two parallel downward forces act along a horizontal beam: 10 kN at x = 0 and 20 kN at x = 3 m. Where does their resultant act, measured from x = 0?
- A1 m
- B1.5 m
- C2 m
- D3 m
Show solutionHide solution
Answer: C. 2 m
The resultant is 10 + 20 = 30 kN downward. Match moments about x = 0: 30xR = 10(0) + 20(3) = 60, so xR = 2 m.
