Q/1 Determine the magnitude FSof the tensile spring force in order that the resultant of FSand F is a vertical force. Determine the magnitude R of this vertical resultant force. Ams: FS= 60 Ib R= 103.9 Ib Q/2 Determine the magnitude of the resultant force and its direction, measured counterclockwise from the positive x-axis. Ans: R= 997.75 N θ= 134.8ᴼQ/3 Determine the angle θfor connecting member A to the plate so that the resultant force of FAand FBis directed horizontally to the right. Also, what is the magnitude of the resultant force? Ans: θ = 54.9ᴼ, R = 10.4 kN
