>>> B The figure below shows an arm that is balancing a carton of milk in the hand. The mass of the carton of milk is 2.13 kg, and F in the figure is the gravitational force on the carton. The biceps muscle applies a force FR to the forearm directed up and to the right at an angle of 75.0 from vertical. The point where FR is applied to the forearm is 8.00 cm to the left of the FB elbow joint and 25.0 cm to the right of the center of gravity of the milk carton. (For simplicity, ignore the weight of the forearm.) g -> Milk 75.0 B -25.0 cm- 8.00 cm What is the magnitude of FB (in N)? A uniform plank of length 2.00 m and mass 33.5 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 720-N person is d = 0.500 m from the left end. magnitude of 7 1 1 1 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N magnitude of 72 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N 1 magnitude of T 3 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N +d+| 40.0 -2.00 m
