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 = 2.74 N and a point of application on the y axis a distance r¡ = 1.76 m from the origin. Force 1 makes an angle of a = 29.2 degrees with the dashed line that is parallel to the x axis, as shown. Force 2 has a magnitude of F2 = 3.04 N and a point of application that is a distance r2 = 4.17 m from the origin. Force 2 is F, perpendicular to a line connecting its point of application to the origin. Force 3 has a magnitude of F3 = 3.04 N and a point of application on the x axis a distance r3 = 1.76 m from the origin. Force 3 makes an angle of ß = 19.9 degrees with the dashed line that is parallel to the y axis, as shown. Force 4 has a magnitude of F4 = 2.74 N and its point of application is the origin. F, F B P A What is the magnitude of the net torque about the z axis (which is directed out of the screen at the origin) in units of N·m? N-m
