(6%) Problem 8: Four forces (1, 2, 3, and 4) are in the x-y plane and act on an irregularly shaped object, as shown. Force 1 has a magnitude of F₁ = 2.66 N and a point of application on the y axis a distance r₁ = 2.55 m from the origin. Force 1 makes an angle of a = 25.4 degrees with the dashed line that is parallel to the x axis, as shown. Force 2 has a magnitude of F₂ = 4.13 N and a point of application that is a distance r2 = 3.87 m from the origin. Force 2 is perpendicular to a line connecting its point of application to the origin. Force 3 has a magnitude of F3 = 4.13 N and a point of application on the x axis a distance r3 = 2.55 m from the origin.
