In the gure shown below. the fulcrum (pivot) is at the 0.40-m mark. The masses are placed at the following locations: m1 = 0.10 kg at 0.05 m; m; = 0.20 kg at 0.20 m: m3 = 0.5 kg at 0.?0 m; and m; = 0.30 kg at an unknown position. With the meter stick supportecl at the 0.40-m mark. what is the position at which mass m4 balances the meter stick? The mass of the meter stick ma = 0.150 kg. Take the center of gravity to he at the 0.50-m mark. What is the torque of a 74 N force that acts perpendicularly at a point that is r = 3 m from the fixed point (pivot) of a long horizontal stick? Give your answer as whole number (integer). The SI unit of torque is N.m
