For the meter stick shown in the gure below. the force F1 is unknown and it acts at the 10- cm mark. F1 is balanced by another force. F2 = 31 N that acts at the ?U-cm mark. What is the magnitude F1 .in Newtons. about an axis through the point B? Please round your answer to one decimal place. In the gure shown below, mass m1 = 100 grams, m2 = 300 grams, and m3 = 100 grams. What is the absolute percent difference between the clockwise and counterclockwise torques if the system is in equilibrium? Assume that the meter stick is uniform and symmetric
