Answer number 9 only
Extracted text: 9. Determine the resultant of the parallel force system acting on the bar AB shown in the figure below. The forces and positions are given in the figure. (Answer: R = 40 b, downward at 3.25 ft from point B or 4.75 from pt A) 20 Ib LLI 10b 40 Ib 10. Two unlike parallel forces of magnitude 400 N and 100 N are acting in such a way that their lines of action are 150 mm apart. Determine the magnitude of the resultant force and the point at which it acts. 100 N B 150 mm
