A horizontal plate OAB of a triangular shape is pivoted at point O. Three forces act c the plate as shown in the figure. Fl = 6.O N, F2 = 8.0 N, and F3 = 7.0 N. F2 is perpendicular to OB. Find the net torque (in N.m) about the vertical axis passing through point o (Consider the counterclockwise sense as positive). 30° A 1.00 m 0.60 m B . 45°/0 0.80 m
