Step 1
Given forces: - 140 lb at 30° - 125 lb at 45° - 180 lb at 0° Resolve the forces: - 140 lb at 30°: Fx = 140 * cos(30°) = 121.24 lb Fy = 140 * sin(30°) = 70 lb - 125 lb at 45°: Fx = 125 * cos(45°) = 88.39 lb Fy = 125 * sin(45°) = 88.39 lb - 180 lb Show more…

Exercise 24: Express each of the three forces acting on the bracket in Cartesian vector form with respect to the x and y axes. Determine the magnitude and direction of F, so that the resultant force is directed along the positive x-axis and has a magnitude of FR = 600 N. Fig 2-37 Ans: F = 434.5 N θ = 67°

Exercise 24 Express each of the three forces acting on the bracket in Cartesian vector form with respect to the x and y axes. Determine the magnitude and direction θ of F, so that the resultant force is directed along the positive x' axis and has a magnitude of FR = 600 N. Fig 2-37 Ans: F = 434.5N θ = 67.9°
