(a) Explanation Given info: The distance between the two scales is 2.50 m , the value of the force at the left side of the scale is 435 N and the value of the force at the right side of the scale is 183 N . The two forces acting upwards and the weight of the body is acting downward. The net vertical force is, F 1 + F 2 − m g = 0 Here, F 1 is the force at the left side of the scale. F 2 is the force at the right side of the scale. m is the mass of the student. g is the acceleration due to gravity. Substitute 435 N for F 1 , 183 N for F 2 and 9 (b) To determine The distance from student's head to her center of mass.

Calculate the anti-clockwise torque and the clockwise torque of the system with the ruler and the washers. Record these values in Data Table 5. Ruler = 11.56 g, small washer = 1.85 g, large washer = 24.30 g. Calculate the % Difference in the Torques and record the values in Data Table 5. Is ΣAnticlockwise torque and Anticlockwise torque the same thing, are they solved in the same way?

A window washer stands on a uniform plank of mass M = 142 kg and length l = 2.80 m supported by 2 ropes attached at the ends of the plank. The window washer has a mass m = 68.0 kg. What is the tension in each of the ropes, T1 and T2, if the window washer's displacement from the center of mass of the plank is x = 0.930 m as shown in Figure 1: Window Washer Problem?
